Caterpillar Face (First attempt with a DIY Macro Rail)
Lens: DFA100mm Camera: k5iis Photo Location: Living Room ISO: 80 Shutter Speed: 1/125s Aperture: F5.6 
Posted By: BrianR, 02-04-2019, 03:41 PM

This is the head capsule of a 4th instar Polyphemus moth. They shed their skin as they grow and the face usually pops off intact. So naturally I have a bunch of wee containers with wee caterpillar faces waiting to be photographed. Why? I don't know, they look pretty cool and there's a decent variety once you start looking.

It's about 4.5mm wide and photographed using a dfa100mm at minimum focus distance plus a raynox dcr250 for about 2x magnification. Same face left and right, it is a composite, plus a focus stacking test of my diy rail, more info in the link for the interested:





And the rail I put together, it's crude but astonishingly works. I've a few more bits and bobs coming in the mail to refine things, I'll probably make a dedicated post when I have more time.

Well done! I have a similar design I haven't had time to make yet.

I'm always looking for excuses to use a Nano

I have many more faces, figured I might as well have some fun with them.

My macro rail was used for focus, but this was a much more forgiving magnification (about half life size) so no stacking required.

Thanks! This is my first go with an Arduino and actually anything electronic. There are so many examples and tutorials, basic functionality was pretty straightforward. My basic programming and electronics courses from many moons ago finally came in handy.
