First shot with 95mm Printing Nikkor lens with crop

Post by Pizzazz »

Gang

Picked up an immaculate 95mm Printing Nikkor and thought I would do a
quick stack to see how it performed.

My quick stack was 100 shots at 70 micron increments and the lens was
set to F2.8 (wide open), mounted backwards on a Nikon PB-6 bellows.

I did very minimal retouching, set the levels slightly, and did a slight
sharpening.

The shot is of a Polyphemus moth wing segment that has the "eye"
partially exposed, as the primary wing has overlapped the "eye" slightly.

Sorry for the dust and scales on the image but I did not want to do
too many corrections.

Mike

Looks good but can you give us a 100% crop? With good lenses it is not possible to judge quality from a shrunk-down image.

I'm a little confused about image size. The image now labeled "100% crop" is 1024 pixels and covers about 39.6% of the width of the first image. Working the sums (ok, the products...), that would make the width of the first frame be only 2586 pixels at 100%. That seems like a very small number for a modern camera, hence my confusion.

Can you clear up my confusion? Was the camera set in some reduced resolution mode? Is the first image also a crop?

Mike, thanks for the email conversation and for editing your post to show a true 100% crop: 1024 pixels = 13.9% of full frame width 7360 pixels.
