This is a test shot using a lens from a Holga 120s camera that was taped to the back of a lens board for my Toyo 45A camera. The lens is a fixed f/8 and it has no shutter of its own.
Here is what I did for this picture, shot two days ago at the Gettysburg Battlefield:
I removed the lens from the Holga, and to get it close enough to the film plane of my Toyo... seeing that I only had a flat lens board available instead of a recessed board... I had to attach it to the back of the board in order to enable focus.
I end up with a 60mm f/8 fixed- aperture lens with no shutter.
I used a 6X7 CM Horseman roll film back and Fuji Acros 100-speed black and white film.
For the shutter, I brought along a dark slide from a 4x5 sheet film holder, and laid it across the front of the lens. I then removed the dark slide from the roll film holder and made an exposure by simply lifting away the 4x5 dark slide and then replacing it in front of the lens after the exposure.
The exposure ended up being about 2 seconds at f/8......it was an extremely rainy and dreary day when I shot this and I was in open shade to boot...I don't think my technique would have worked very well in the direct sun.
I am much more pleased with the result than I thought I would be...the subject was fairly flat, but the image still ended up with decent contrast......albeit, shadow detail is lacking....so more scientific experimentation is in order with proper exposure and development combinations.
I am pleased with the fall-off at the corners and the lack of focus at the edges, which are the primary features I was looking for.
