BECAUSE you teach them how the lens actually works. A normal photographic lens doesn't compress space. Period it doesn't. You moving it does. The only reason you couldn't' use a wider lens has zero to do with lens compression. Its has to do with what you want the image to be in relation to a whole bunch of other stuff spatially and the ANGLE OF VIEW of the lens. That has just literally zero to do with Lenses compress space. Spatial relationships compress or expand space visually. I could teach people that Sun goes around the earth cause it looks that way, but it's still wrong. It's crazy to say don't teach something because you don't think it's used. I don't need to know circles of confusion I only need to know that f1.4 means less area is in focus and f64 means lots is in focus. I for sure didn't need to learn to disguise artist by their brush stroke styles. (yes I did have to in history of American painting)
I can think of a lot of cases where your last line is pretty use full. Lack of a macro lens, photographic survey, barriers to getting close to a subject. Shooting still plates for matte paintings that have to match Film plates but you only have the right focal length and not the right camera. (super35 vs ff or larger) Not every situation works out as an ideal situation, knowing how things actually work is kind of handy.

Randy, the question is not whether you could do all that (And indeed, technically, you could) but WOULD you do that? ... for a $300.00 jewelry shoot?And let me put it this way.... I did an on-location car shoot for Mazda in the 80s. On 10X8 Sinar with a 980mm Schneider lens (Very little DOF at f:32) (Needed 3 tripods for film, middle standard and lens) How could I have done THAT without the long lens? And still give the client the 10x8 tranny?Why teach stuff to people if they're never going to use it...

I could technically shoot with a 90mm on my 8x10 (SUPER WIDE)and crop that shot to have the same exact result if the camera is in the same exact spot as a 35mm camera with whatever lens for the most part. The only difference is angle of view. It would be the same in all other aspects. The only time it wouldn't is if there is lens distortion. It would be a total pain to shoot like that and not at all practical but the result IS the same. Once you move to compensate for the focal length then you are changing all kinds of geometric relationships which is the only reason it its different. Right? You change Focal distance, actual distance relationships and whatever. All that is true and all that is real world. That doesn't change the FACT that any rectilinear lens on a camera at the same position produces that exact same result if you crop them to show the same thing. Lenses do not compress space. Spacial relationships of camera to subject distance and focal distance do. Which is what Herschel is doing in his example. The lens isn't compressing space Herschel is by changing the relationship of the camera to the subject.On Fri, Feb 19, 2016 at 9:48 AM, Herschel Mair <herschphoto@xxxxxxxxx> wrote:TECHNICALLY it's a myth... CREATIVELY, a longer lens allows you to get further away from your subject and by so doing gives you a flatter perspective. Why over-think this? If I want to shoot a jewelry shot on a model, I use the 300mm f:2.8 because it allows me to get the flattened background and it allows me to get tiny DOF.... I don't use the 24mm and then crop it... There's no way for me to do that pic unless I have that lens... Technical perspectives are only as useful as they support the creative eye. Beyond that they are for technicians, not photographersOn Fri, Feb 19, 2016 at 4:24 AM John Gulliver <j.gulliver@xxxxxxxxxx> wrote:I agree about Feininger Snr. and his book. He wrote well. I know this picture too, for which he invented a tripod with an extra leg to support not only the camera but the long lens to reduce possible vibration.

My first purchase of a photo book was one by Andrea Feininger in which he showed the use of an extremely long telephoto lens from out in NJ looking towards Manhattan and it compresses NJ into a series of hills and sort of pasted the Empire State Building in at the back. Every time I drove to NYC I thought of his work with the Pulaski Skyway and the flattening of NJ.
