5x7 Ektachrome, Epson 4990 scanner -vs- Wild M420 microscope

[Bernice Loui]

Lots of discussion about scanning film to digital files and all related to digitizing film into digital files. Out of curiosity put a sheet of 5x7 Ektachrome made decades ago as part of checking out a Goerz 14" f9 APO artar before taking ownership. Put the 5x7 color transparancy into the 4990 scanner converted it into a digital file.

Did a crop section of this area of the image.

Further crop to the STOP sign. No attention paid to optimizing scanner focus and ...

Same STOP sign imaged with the Wild M420 macroscope. Stop sign measures 0.026" across with the image length about 6.8" or about 260x.

I would say that the high praise for Goerz Lenses is well deserved. I have a Red Dot Artar that was rescued from a Robertson process camera. I had a Packard shutter, it's setup for my 11x14 studio camera, it's on my list. I shot a bunch of 5x7 Ektachrome in the mid 80's, beautiful stuff.
