I'm doing some research. What do you think the size of the market is (in North America) for advanced amateur and fine art large format 4x5 photographers? The type of people who can afford to buy $1000 plus 4x5 field cameras like Technikas, Toyos, Canhams, Arcas and Ebonies. Let's not include the overlap from commercial photographers using studio cameras like Sinar Xs and P2s; hardcore ULF users; or all the fine people who get by cheaply with Graphics and such. In other words, how many people have the money and desire to buy a nice 4x5 field camera? Thank you.
