My grandfather had a lake house. On the wall was a panoramic photograph of the lake. That image is burned in to my memory (haven't seen the photograph in over 35 years).
Saw an article in View Camera and thought it would be cool to shoot a panoramic format. Decided on 7x17 because film/lenses/holders seemed more available/affordable than some of the larger sizes. I just love the format. Now all I need is for MAS to deliver a boatload of 8x20 Lodima :-)
