I made some tests using nylons behind the lens. Here are the details and I am glad to provide the full test image folder to anyone interested (3 scenes x 3 apertures x focus close/focus far x with/without nylons). Here are the findings:
Helios 44 lens sets wide open, mid and stopped down, focusing on close subject and then a far subject.
1 set of each photos with Hanes absoultely ultra sheer style 707 "Barely There" stretched across back of lens while threading on (M42) adapter and one set without the nylons.
Results:
1. Aperture makes no difference, nylons are too far out of focus range.
2. color cast is present.
3. stretch quality doesn't matter much, brickwall samples did not have an even stretch- there was some slack and bunching of fabric, barely noticeable.
Sorry, cannot get sample image to upload. _________________ Ian |
