Re: Would you recommend a tripod or monopod for macro in the field?

Actually, a device like that would be rather simple to make. Just mount a Stackshot on a pistol grip :-k

Somewhere in the archives is a post by LordV showing how he uses a pole or walking stick to stabilize the camera. He also has a Flickr account showing it.

Re: Forum upgrade completed

The new format is fine with just one tiny niggling little issue. Firefox doesn't show an icon on the tab. I assume you're talking about the tab in the browser tab bar. As far as I know, nothing at photomacrography.net or photomacrography1.net has ever displayed a site-specific tab icon. If you have...

If the virus can only survive for 3 hours on cardboard and 72 hours on plastic, why would you not reuse a mask after 72 hours?

You might consider an Olympus which does in camera focus stacking. I don't know if Canon has this feature.

p.s. Renting a camera and testing various lens would be beneficial.

I'm using a Teensy 3.5 (arduino compatible) and a Nextion Enhanced 4.3" touch screen on a rose engine. Basically, it is similar to a 4 axes CNC. The touchscreen has 22 different pages. My camera setup uses a Teensy 3.2 and a bluetooth connection to an Android smart phone. There are quite a few funct...

One thing that helps when disassembling (and reassembling)linear slides is to remove the rail from carriage. In other words, have the carriage on the table not the rail. I think this should apply to stages as well. Remove the part that doesn't hold the ball bearings. Even on a towel, the little ball...

I designed it in Fusion 360, then 3d printed it in ABS. Each ring was printed separately to avoid using supports and to make it easier to clean up the inside surfaces. Acetone was used to glue the sections together. It was one of my earlier designs using Fusion 260, so it's not parametric. That woul...

When you said dental wax, I thought perhaps machinable wax would work, but the melting temperature is probably too high. Dental wax seems to be readily available at any drug store pretty economically, but I don't know if it's the same type of wax as Thomas Eisner used.

Not missing anything. I think it's fairly weak, so it might be removable. There are probably better adhesives that can released easier without harmful chemicals.
