Here is my latest attempt at a photo.
The main light in the living room was left on as the other half was watching tele and sewing at the same time. By the time it was switched off I was in bed!
Never the less a lesson learnt, and you can see me on the watch!!
Yeh I know well out of advert material, but I like it as first attempt under exceptional lighting circumstances, like no proper lighting, no proper background eg and no understanding. At least it is not at the normal angle!
I have included this as we did not have our planned day out today as a substitute for anything that may have gone on today. Sorry Steve, but it was a good laugh.
Here are the final images that were chosen by Kate for her portfolio and web site. There are also a set of prints for her portfolio.
I learnt so much in a short time with this project, from guidance re lighting from Mr Steve and his constructive comments, to how to place the camera, to understanding the reality of the difficulty of "on-site" photography, balanced against the studio place settings and room sets. The combination of comments from Adrian and Steve have made me realise the differences, and how to go forward in the future.

the curtain in it's location

Yes, the room set is a brilliant idea, but there maybe a place for in situ as well. I look forward to the next project/s.
Well what can I say. The visit just reinforced my feelings about the whole business of photographic studios. A very workmanlike place, just as I had expected,. and the images produced were at best excellent from what we were shown.
I cannot express my pleasure at seeing a master in his own environment. Adrian was like a breath of fresh air, and very easy with his comments. I would imagine he is a joy to work with, once you really got to know how he works. The little nuggets of information passed over could easily have been missed. As he described it was a jobbing studio, but I am sure he was being very modest about his talents.
I realise that there is 40+ years of experience going into the studio, and I would not have a hope in hell of getting anywhere near to the quality that Adrian can achieve.
The earlier group who went on Wednesday had a longer and more informative visit, which unfortunately for those of us who have to work for a living have missed out on. It would have been nice to see some action, even a demonstration of the lighting techniques. I am sure that may have been possible to see the effect of this when we were there, perhaps I should have asked!
I personally got a lot out of the visit, but unfortunately, and sadly, it only reinforced my belief that with my current abilities and time commitments and experience and cost and age and expense and contacts and lack of structure on the current course is preventing me from pursuing my passion to create the images I feel I can do.
But I did hear the mantra yet again of if the work does not suit or you have an awkward client or you can't cover you costs then do not do the work, in addition to clients always wanting to get more for less! This I have heard from many quarters in this profession, and I think you have to be very strong to exist, and Adrian has achieved this, even if in quiet periods he has done other things.
But this is a business first, and photography second (but the quality counts beyond the ordinary), and that is the biggest disappointment for the current course, and to be introduced to environment we were in, is that the importance of business has not been placed at a higher importance level, bearing in mind the expertise available.
It is with much regret that I will have pull out of the current course, as I received no assurance on the day that the structure of the course would improve in that direction. Having worked in private companies on a very business like environment then I am disappointed that progress has been so slow in this direction, only highlighted by the visit today.
But please keep in touch as I will continue to update this blog.
Hi folks, back from my travels. A few pics that what I tooked whence I was there.
LONDON
One sunny and misty morning, new architecture arising into the sky. going to be the tallest building in London, for a short while anyway.
Architectural symmetry
PARIS
the butt end of France
Not what you expected ! BUTT they are everywhere, butt everywhere, this is neat!!
In no particular order
After the fire back to base
Alternate forms of wheeled transport
you know where these steps are
Well I had to didn't I
My after dinner coffee

Now for the non-holiday stuff

Of course the whole purpose of going to Paris was to carry out this fashion shoot which I had been asked to do, mainly handbags, but the by product was the clothing as well. This is Sami and she was getting a bit chilly at this stage although the sun was still out, and it was mid afternoon.
Here are a few of the images from the day, love the bag.
This was her first outfit, looking very glamorous. those shoes.
Ha Ha If you believe this then I have lead you astray. But I did take advantage of the situation at the Sacre Coeur, until they politely asked me not to. But I was standing next to the photographer!!!!!
I went to see Southampton FC play Coventry FC, and the match was good with the first away win this season for Saints, but I was also watching how the pro photographers were operating. Hey, not only do they seem to get to the right end for the action (depending on the client) they are very well versed in the action and manner in which the game is played. Knowledge is vital of the subject that you are photographing, be it football or interiors for example.
It is the understanding and knowledge of the the environment that counts so as to enable you to get the correct image. Several of the photographers were editing the images as they took them, while the action was elsewhere. I have seen the resulting image on the Southampton web site and can relate them to what I saw them doing.
For instance they were editing the images whilst the players were returning to the centre circle after a goal was scored. Making best use of the time available whilst on the job. This cuts down post editing time.
Therefore the lessons learnt from these 90 minutes were :-
Know your subject in depth
Know the enviroment that you are taking your images in
Assess the lighting difficulties that you are going to encounter
Be prepared to adjust to the conditions
Make the best use of the time you are on the job
Edit where necessary as you can going along, where possible
Save time on post production where possible by pre editing
Taking the best shot you can at the time
Keeping up with the action
For photographers who enjoy travel, meeting creative people and solving visual challenges, a career in Advertising is highly attractive. Advertising photographs are used to help describe and sell a product or idea or service, and are usually accompanied by a short phrase or strap line.
The work is varied and very exciting and very challenging, both visually and keeping the client happy in presenting the product in the way he sees it. If you can develop an ability to interpret ideas and stories through original and emotive photographic images then you maybe able to enjoy a good career.
The job involves creating seductive images that are used to support a marketing idea in answer to a photographic brief given by the client, a designer or an advertisement agency. The images are usually used in local and national advertising promotions. Subject matter is important but is often categorised into still life, portraiture or landscape. The job involves also “pack” or “pack shots”, and these are generally produced by salaried studio employees. There are many parameters within these field, and definitions can be blurred. A lot of the work for these categories is done in the studio, with suitable lighting, but some is done on location. All images must be well lit, either naturally or artificially, or both, and are used on packaging, point of sale and in catalogues.
With this kind of photography, you generally have to have a high profile, work out of a studio, and be based in large cities, and secure work on past campaigns, so you need to be very creative and imaginative with your photography, within the confines of the client brief. You either are commissioned, or work through an agency. Generally the photographer is a specialist in his field, for items such as food, cars, furniture, financial services. Assistants will be also be employed due to the magnitude of the work, as it is not possible for one person to carry out this work. There are many elements to this type of work, not least constructing studio details, sets etc where necessary.
Advertising photographers are commissioned to take photographs that are original and set the product apart from the competition. Occasionally the photographer has license to produce the images. But the photographer must have extensive knowledge of the history of advertising and the many techniques of image manipulation to achieve the final outcome that suits the client and the product. He also has to have expert knowledge of lighting, set construction and innovative use of the new digital techniques.
The use of agencies will entail a percentage commission, but often an assistant, or 2 etc, will be employed who are often well paid, on a day-to-day basis plus expenses. This will all have to build into the costs for the client at the end of the day.
There are no set qualifications for this type of work but the general introduction to this field is by working with a photographer as an assistant and learning on the job, until you gain enough experience to either go freelance or work on your own reputation.
Membership of various organisations can be beneficial, such as BIPP and AOP.
Health and Safety is also an issue and is subject to a separate issue with regard to this blog. not only is the consideration for studio and location, but also for the photographer who may have to carry a heavy load.
There is a very interesting article on the Skillset web site regarding the Labour market for photographers/photo imagers and it is entitled ;-
Photo Imaging – Labour Market Intelligence Profile
This shows how the market is at 2010 and how amateurs are affecting the pricing in the market.
This also shows the distribution of current skills and distribution within the skillset that you might be looking for and in the various parts of the country.
When I can work out how to add a PDF doc I will add it here.
The world of Architecture is very varied, and can reach that rarified atmosphere of imagination, beyond the everyday and normal. Various competitions are organised, of which I have come across one, and list the link below. It is surprising with some of the results, some made, some still on the drawing board.
We had a discussion about business cards this evening.
I feel that this is possibly the first contact that a prospect has, along with the web site if passed on by word of mouth, therefore the design of the card should be simple, and clear, as to what you do and photograph. In my case the speciality is interiors and jewellery, so my card needs to reflect this.

I was talking to an acquaintance earlier who deals throughout Europe with business grants. He could not help in this instance but he has put me onto this web site which is of interest as it sets out the different areas that loans can be obtained from.
Also see the link in the links list opposite which gives an idea of how to produce a business plan, and provides some samples, but not for photography, still relevant though.
There is also the Business link web site which is of extremely good practice and also gives excellent guides and can also enable you to work your way through a business set ups, ask's relevant questions and provides a list from how to start and how to see your way through.
There is also the HMC web site regarding all tax affairs.
Looking to learn about tilt shift lens I came across this article on Photonet By Frank Sheeran, who I hope will not mind me copying for reference purposes. Here is an image of the Canon 24mm lens, average price £1700
The college have one to borrow so I am looking to have a trail run prior to purchase. I will do my own research when I have had use of this lens, so in the the meantime I have to read this article.
How Shift Lenses Change your life
by Frank Sheeran
How to Take Bad Pictures
Simple formula for poor pictures: put a building in the shot, then don't aim level. You end up with what is called "converging lines." The left and right side of the building seem to meet somewhere above the picture. If that's what you wanted, fine. If not, get it under control.
The Band-Aid
Level off. You need to have the lens (and film plane) parallel to the edges that you don't want converging. (You don't actually have to be parallel to a side of the building, just an edge.) For most buildings this means vertical. You probably have zero height compared to a building, so for practical purposes this means aiming at the base of the building. But, when you do this, you are probably cutting off the top. So, you will back up quite a ways to get it to fit in. This makes it small.
You'll notice now that the building is only using the top half of the film. My example image shows beautiful green meadow, but you've got parking lots and hot dog stands. At the very least, you will have to crop half the shot away, and enlarge your grain twice as much as needed. Is there a better way?
Film Geometry
Before looking at the real answer to this stumper, look at the numbers in image 2. "35mm" film has images 36mm wide by 24mm tall. The "centerline" of each shot is exactly half that: 12mm down for horizontal compositions and 18mm down for vertical compositions.
Shift Lenses
Shift lenses do a few tricks but perhaps the main professional gimmick is letting you control that centerline. Within limits, you can put it where you want it, without changing the angle of your camera (and screwing up the perspective).
Shift lens documentation should tell you how much they shift. Let's look at the Canon TS-E 24mm/3.5L. Like the other TS-E lenses, it shifts up to 11mm. This is the distance the lens elements move up, but that also means the image moves exactly that much on the film. Since film images are upside-down, moving the lens up moves the image down. This means... fewer parking lots and hot dog stands. And you can go back to your original vantage point and get a bigger image.
How Close?
How far from your target do you need to be to get the desired shot without twisting the perspective? Believe it or not, no trigonometry is needed. It depends on the height of the target above your eye level, the height of the film above the centerline (red, above), and the lens' focal length.
Using that, solve for anything if you know the other three. In practice, you know the focal length and height-above-centerline numbers exactly, or can dial in the height-above-centerline you need with a shift lens. Distance may be harder to estimate, and height can be tricky. With buildings, you can usually guess 5 meters or 15 feet per story for commercial structures.
For now, this can help you picture what shots a given shift lens lets you take. For instance, since the height-above-centerline is 12mm for a normal lens and twice that (well, 23mm) for the TS-E lenses with maximum shift... we can get twice as close to our target. Or, shoot a target twice as tall. Or use twice the focal length (say, the TS-E 45mm instead of a normal EF 24mm).
Later, on a shoot, this can avoid a certain amount of trial-and-error. For instance, say you have a 24mm lens with 11mm of shift, and a four story building on a city street. You can back up to 65 feet away from your 60 foot target. The formula says 65/60 = 24/X. X is about 22mm. You know that's right at the limit of your shifting and the corners may darken somewhat. On the other hand, you not to even bother getting your 1.4x TC out unless a vertical composition would work (vertically, 65/60 = 36/X, X would be 33.3mm, and a you could get a maximum height-above-centerline of 18mm + 11mm x 1.4, or 33.4mm).
Drawbacks
When maximum shift is employed, shift lenses (with their unnaturally wide field of view) can show some light falloff in the corners, due to basic optical properties. In addition, even the widest filters may be visible in the corners of the shot. Smaller apertures typically fix the first problem but accentuate the second. Hopefully you have the option of backing away from your target and reducing shift slightly. If not, consider using an auxiliary filter holder instead of screw-on filters.
There are not yet any auto-focus shift lenses, even the Canon TS-E lenses with the auto-focus mount. Some shift lenses are a bit more primitive, making you stop down manually before shooting. This will be true for any "old" mount with manual aperture control, because it would take Rube Goldberg hardware to translate the mechanical movement at the mount to movement at the aperture, when half the lens moves up and down.
You will be paying quite a bit extra, both for the optics that make a larger, shift-able image, and the hardware on the lens that let you move the glass up and down. Even then, the lens will probably have a smaller maximum aperture than you'd expect. For instance, a Canon 24mm/2.8 is about $500 while the shifting 24mm/3.5 is more like $1200 on the street. If its any consolation, the makers are probably losing money on every one they make due to the low volume of production. You'll see all three Canon TS-E lenses for the same price, even with their vastly different optics, because Canon is offering them to complete its lineup, and not attempting to price them to recoup their cost.
Tele-Converters
A tele-converter (TC) is a lens group that attaches between your objective lens and camera body. They typically magnify the image size by a factor of 1.4x, 1.5x, 2x, or 3x. TC's also (sadly) increase your f-stop by the same factor. Generally any older TC or 2x TC with less than seven elements will be crap.
On shift lenses, a TC will also (for practical purposes) increase the amount of your shift. The Canon TS-E lenses go from 11mm shift to 15.4mm (1.4x) or 22mm shift (2x). Looking at image #3, guess where you can now place your ground level. The horizontal format can suddenly lose the bottom third of your building, when the centerline moves to 10mm below the bottom of the frame with a 2x. The vertical format can move the centerline to 4mm below too. (Just as lens specs are not exact, teleconverter specs can be pretty loose. A nominally 2x converter may be 1.8x or 1.9x. Never seem to be better than advertised, even for Leitz and Zeiss.)
Now, compare the Canon TS-E 45mm/2.8 vs. the TS-E 90mm/2.8. With a 2x TC, the 45mm/2.8 turns into a 90mm/5.6... but with 22mm shift possible instead of 11mm. Which sounds like more fun?
Since TC's in effect take their picture from the center of the objective lens' image, they avoid problems that tend to arise in the corners of the objective.
But Wait! That's not All!
Any Shot with Lines!
The example buildings can be replaced with trees. Show those forest canopies while avoiding the "acid trip trees" look. Or any other shot where there are two parallel lines... and if that sounds like "most shots" you get the picture. Back before rolls of film were invented, there was a time when all camera lenses shifted, and truing perspective was considered as important as focus and selecting shutter speed and aperture. (Back then, they also used a variety of terms for shift: rise was shift up, etc. Archaic people still do so today 8-)
With the first professional-use "box" cameras (as opposed to bellows cameras), a generation of photographers - and photograph viewers - grew up not having this advantage.
As time went on, all the serious 35mm camera marques issued "perspective correction" lenses. Or perhaps I should say, lens, usually with a focal length of 35mm. Zeiss does a 35mm for Contax, Leitz does a 35mm for Leica. Olympus and Pentax have one too. Minolta made a 35mm for the old manual lens mount, but doesn't have one for the auto-focus cameras. Nikon made (and makes) the 28mm and 35mm. Canon had the TS 24mm and 35mm for the manual mount, and the TS-E 24mm, 45mm, and 90mm for the current electronic mount.
Distortion!
Besides fixing perspective, you can use the same feature to screw up normal perspective. I took a band's CD cover picture, where the guitars are the size of battleships and the guitarists' heads are the size of gnats. Art is Truth.
Panoramas!
Look at the example vertical image #3. Assuming your shift lens shifts left and right (Canon TS-E's do), you can take the left half and right half of a panorama on separate frames, and combine the images in the darkroom or a photo touch-up program. There will be some overlap to help you assemble the halves into the final image. This overlap can be nominal if you use a TC.
You can end up with a scene that uses about 70mm width and 24mm height. This will give you strictly higher imagequality that you'd get with a 6x6 medium format camera and cropping to get a panoramic slice - merely 55mm x 20mm. If anyone cares, that’s 1.5x larger negative... advantage 35mm.
The Canon TS-E lenses will shift in any direction, and have clicks every 30 degrees. You can thus also get a shift somewhat up or down at the same time you shift hard left to get one half, and reproduce the exact shift amount and angle to take the second half.
Unsightly Blemishes!
Normally you can change your viewing angle to select the foreground and background that surround your actual subject. You may have artistic conflict, however, if there is a strong rectangular element in the subject that you want to render squarely. Examples are mirrors, railings, and windows.
If you face a mirror head on, you will be in the shot. If you move to the side, it turns into a parallelogram. With a shift lens mounted, move the camera to the side, turn the film and lens parallel to the mirror, then use shift to get the original composition back (more or less).
Sometimes you have limited access to a fixed display, especially in tight interiors. There might be a ceiling support exactly where you'd like to stand. Set up to one side and shift horizontally to reframe.
Depth of Field!
Besides shifting in any direction, the Canon TS-E lenses also tilt. Actually, this has nothing to do with the above shift stuff, except that the only lenses that tilt are the Canon TS-E's. What does tilt do for you?
Normally, everything in a plane a set distance from, and perpendicular to your lens will be in focus. When you use lens tilt, you forego the "perpendicular" constraint. You can tilt that plane quite severely if desired. The plane of the back element of the lens, the film plane, and the focus plane will all intersect.
The classic example is for landscapes. You have wildflowers at your feet and Alps at infinity. f/22 won't give you the depth of field you need (well, it would at 24mm but at the sacrifice of sharpness). As its just after sunset there's not much light, and there is also a wind moving the flowers so a long exposure won't work. Fast shutter dictates big aperture, which means lousy depth-of-field... normally.
As you tilt the lens, you make the focus plane tilt. However, a small tilt of the lens creates a huge tilt in the focus plane. Just 10 degrees of lens tilt can rotate the focus plane to the point that wild flowers a meter away, at the bottom of the frame, are perfectly focused as are distant alps.
There are very mathematical explanations to calculate all the exact effect, but I don't know how you could use them accurately in the field. It would be nice if there was a focusing screen with a half-prism focusing aid at both the top and bottom of the frame. But there's not. The camera could also calculate this information for you and display it.
The other tilt trick is just the opposite. Say you want everything out of focus except for the subject. Say there is a row of columns ahead of you, running left to right. Tilt like mad, focus one column, and the equally distant neighbors to the left and right will be fuzzy.
Why You Can't Get a Good Exposure
Wide angle lenses get darker the further from center you get. This is called "cos^4 vignetting" and is due to the light hitting the film at an angle. This is a problem when the lens->film distance is small compared to the image width.
On SLR's, wide angle cameras use a "reverse telephoto" group at the back, so the rear of the lens is far enough away to leave room for the mirror. This extra glass hurts quality, but means that even a EF14mm/2.8L is about 40mm from the film, which is 36mm wide... which means "cos^4" is NOT visible on SLR wide-angles. Rangefinders like Leica M and Contax G and Mamiya 7 have no telephoto group, so their images are sharper - but the back of the lens is VERY close to the film, and the corners are much darker.
So what does this have to do with your shift lens? Everything! Shift lenses make a picture much wider than a normal lens, but the distance from lens to film is still about 40mm. Your lens shifts 11mm, so the image is 36mm (film) + 11mm * 2 = 58mm or so. Unshifted, only the center 24mmx36mm of the image hits the film, and has no more cos^4 vignetting than a normal 35mm. However, as you shift, the darker part of the total image hits the film.
If you externally meter, then a meter reading good for a centered shot will be too short an exposure for a shifted shot. How much too short? Who knows, bracket! 8-) On the other hand, the camera meter depends on taking readings of light off of partial reflections, and depend on the angle the light hits the sensors. When you shift, the light comes from a different direction and the sensors may see none of it (or too much), so they will suggest a bad exposure.
How to Get a Good Exposure
If you don't want to bracket, you need to build up some base-line cos^4 data for your lens. Perhaps the following might be agreeable:
Build comparison series: on slide film, photograph a grey card metered with 0 shift and no exposure compensation, then -1/3, -2/3, -1, -1 1/3 stop. (either internal meter or external is fine)
Find worst-case dropoff: shift maximum (horizontally if you can shift sideways), and use the same shutter and aperture as the first shot of your comparison series.
Develop these shots.
Using the center of the series shots, determine whether the maximum shift is -2/3 darker or whatever. That maximum shift is 36mm(width)/2+11mm(shift)= 29mm from image center. If you want, measure the falloff at other distances.
Then: after metering a scene with a handheld meter or unshifted lens, set the exposure manually but with the test-result compensation. This should be perfectly accurate with one caveat: Because the darkening is progressive, the maximally-shifted side will always be somewhat darker. For arrchitecture, this is perfect - it saves you from using an actual graduated filter to bring the sky and ground brightness closer.
Since you may not be able to see this difference in the viewfinder, your probably still want to bracket, but bracket from the external/unshifted exposure to your test-result maximum compensation. Some picture in that range should be ok.
Wish List
The only return I get on writing an article like this is the right to voice my own opinions - and hopefully Canon's listening!
New Lens
More than anything in the world, I want a 35mm tilt-shift lens. The gap between the 24mm and 45mm is just too great. And, the 24mm is not sharp enough to have its images cropped 50% without pain. This lens physically works with the Extender EF 1.4x teleconverter (TC), but resolution seems to suffer somewhat. In effect, the TC creates a very expensive, 35mm f/4.9 lens with less than ideal sharpness. Instead, a one-piece TS-E 35mm F/2.8 or 3.5 lens should have much better optical quality (no TC), as well as being cheaper (no TC), lighter (no TC), and brighter (no TC).
It would be nice if the TS-E lenses became TS-EF - autofocus. I firmly believe that everyone's 24mm (and 35mm...) lens should have tilt and shift, for when they are needed, but autofocus when they aren't. Canon, with their great all-electronic mount, could easily allow this.
New Focusing Screens
We need a new focusing screen for shifted composition. Canon makes a screen with a grid, for verifying perspective. This is great, except the TS-E lenses are all manual focus, and the grid screen doesn't have a focus aid. There is a perfectly good screen with the usual split-circle, but no grid lines of any sort. So, we are left estimating ranges and looking at the distance scale on the focus ring.
For tilted composition, the situation is even worse - the distance scale only tells us what is happening at the image center. The scale might say 3 meters when the lens is actually focused at infinity on one edge and 50cm at the other. Calculating lens tilt mathematically is practically a black art. I only know a couple people that even know how, and they don't do it in their head on the scene. They guess a tilt, then squint at the viewfinder trying to guess if it is sharp enough. This is hard at f/3.5 (the Canon 24mm lens) or f/4.9 (same with 1.4x TC). I'd like a focusing screen with the normal split-circle focus aid, but instead of merely the image center, have a circle (or major portion thereof) at each corner or perhaps centered on each of four sides.
More Advanced Camera Electronics
An second alternative would be a camera that tells us what focus we're at, at the extreme edges of the camera. This would involve the camera asking the lens 1) focus distance, 2) tilt, 3) rotation of tilt, and 4) a constant or two related to focal length. The camera then calculates the focus distance extremes and displays them on the LCD. A photographer who could estimate ranges accurately could adjust the lens until the readout matches his estimates.
A third alternative would have two focusing rings for near and far focus. It would use Canon "E-M". (This means that the focusing ring is just an electronic input sensed by thecomputer, that drives a motor to change focus.) We would get a focus motor, and a second motor that tilts the lens appropriately. The focus rings would be right next to each other, so normal operation would involve grabbing both simultaneously.
If this two-ring lens had autofocus (in untilted mode), Canon wouldn't mark distances on the focus rings, making the split focus screen mandatory. If the lens was manual focus only, the rings would have full markings, and ranges would be estimated by the photographer. I don't even postulate a camera with AF sensors at the frame's extreme corners, that attempted to tilt, rotate, and focus, simultaneously 8-)
Adding electric control of the current tilt probably would be awful. Hopefully, just as many lenses are now internal or rear focus, the tilt effect could be accomplished simply by tilting one internal group.
Conclusion
I hope at this point, you are sadder but wiser. Ideally, you should be discontent with every non-shift (and non-tilt) lens you have. This consumer revolt will get back to Canon et al, who will finally start making the lenses the world really needs.
Here is a video showing the Scheimphllug principle re tilt and shift lenses.
