"Amateur medical imaging" Sat 15-Sep-12 12:38 AM by kenuck
Using a V1 for macro: A friend wanted pictures of her kidney stone before sending it in for analysis. I mounted the V1 + FT-1 to my old bellows + 50mm f/1.4 D lens. I had to put an extension tube in front of the bellows so that the "foot" on the FT-1 didn't hit the rails on the bellows. I found I couldn't just use extension tubes as the V1 gave an FEE error, even though the lens was set at f/16. Another option would be to use extension tubes and reverse the lens, but I couldn't find my reversing ring.
Depth of field is always a problem in cases like this...f/4 1/3 sec electronic shutter, remote trigger, un-cropped. Focus on nearest side, Levels and moderate sharpening
So I took 5 images focused across the depth of the kidney stone, then merged them in Helicon Focus. The stone was about 4 mm across and apparently very painful - it looks like cut glass!
