If anyone is wondering about the comment on the border, the picture is here: http://www.apug.org/gallery/showphot...0&ppuser=12229
My enlarger (LPL 6700) only came with 35mm negative holder. I am too much of a cheapskate to buy new holders for the three 120 formats I use but I do have a CNC router at work so I used this to make some new holders. Unlike the 'proper' holder though, My holders have a thick base (about 3/8") and this thickness under the negative seems to cause a little bit of diffusion and/or reflection around the edges. Usually it is cropped out and causes no problems but sometimes it seems right to leave it in. Especially on square images for some reason.
