I am under the impress -- which I hope is true -- that digitizing from a large format transparency is preferred, rather than digitizing from a 35 mm transparency. Given that assumption: Large format transparencies are far more preferable than 35mm becaus ethey retain much more information should you intend to scan them. 1. Are large format cameras common? 4 x5 in view cameras are common, 8 x 10 less so and 11 x 14 in. rare.
What type of photograph studio would own such a camera? Most studios work in 4 x 5 in. format.
2. Are large format cameras movable?Yes, but requires a sturdy tripod Could one be taken on location to photograph items? Yes.
3. What is the down-side of working with large format cameras?Depends on what you are working on....the equipment is expensive ($1500.00 and up w/lens) if you are shooting flat art, then make sure you have a flat field lens to do the work. Also, there are several digital backs designed to fit onto a 4 x 5 camera to do direct digital capture (also expensive: $15,000.00 and up).
Scanning 4 x 5 in. transparencies at 5000 pixels will cost you about $28.00 per but you will get a reproduction-grade file.
