Portrait of tiny moth

Post by Charles Krebs »

This (unidentified) moth was only about 8mm long, and was photographed at about 10X. So the total field width in these shots is about 2-2.3mm.

Impressed by Riks Fritillary butterfly egg results, I wanted to try a Nikon 10X microscope objective on bellows instead of the macro lens I would otherwise use for this magnification. A year or two ago I had tried a different 10X but was plagued by serious chromatic aberration, and gave up on it. This objective is much better for this use, and I was pleased with the results.

You get great resolution due to the large aperture, but it sure does take a pile of images combined to get any depth of field! (The top image is from a stack of 95 images and the lower from a stack of 102).


Nikon CF N 10/0.30 objective on Nikon bellows. Camera was a Nikon D200. Images stacked with Helicon Focus.

Very nice, Charlie.

BTW, when I started serious stacking, I've realized that I needed to invent a new unit of equipment life: specimens per camera.

You compute it by taking the expected shutter life, dividing by the average number of images per stack, and dividing again by stacks per subject.

The final number turns out to be surprisingly small -- maybe a few hundred for my Canon Digital Rebel.

This would be depressing, except for one thing. Although the camera is thoroughly obsolete at over 3 years old, it hasn't actually worn out yet.

Maybe, just maybe, if I shoot a few more deep stacks, I'll have an excuse to upgrade! :wink: :D

Strange how the top eye in the lower picture seems to have some adventitious hairs growing out of it but the lower one does not?

Incedible photos Charles. Lots of details to look at over and over again.
