Testing Barrel Lensesgreenspun.com : LUSENET : Large format photography : One Thread
I am the guy who is wanting to do macro work with 8x10 format, one to one, or even 3 to 1. I wanted to do a test using an enlarging lens on my camera ( Schnieder 150mm APO HM). In addition to the enlaging lens test; I wanted to test two other lenses that might be good for this application. I was able to pick up a couple of lenses on ebay; (2 lenses for around 200.00). Schnieder 150mm G Claron, and 4" Red Dot Artar. The Artar is not corrected for 1to1, but it is short and supposed to be a good lens. Each of these lenses are not in a shutter. I am going to do my tests with flash, and in a dark room. I will use the lens cap as my passive shutter. Can anyone recommend a chart for me to photograph? Other than a chart , can anyone recommend something else to photograph? Also any pointers on something I have over looked. I will make sure everything is square, level my front & back standards to subject matter plain, etc. I would appreciate any pointers. Thanks in advance. richard
