Re: Lens test wafer (RobertOToole)

but my comments seem more appropriate here. I agree -- no problems at all posting here. By the way, all credit to Pau for initially suggesting Robert for this month. The choice might seem obvious in retrospect. But the timing was only a day after we first heard of Robert's passing, and I for one wa...

Re: Chrysoperla carnea (common Green Lacewing)

This is in fact a dead lacewing, I picked it up on its wings with big flat tweezers, put it on a piece of paper and slightly pushed it against the rough surface until the legs grabbed onto it and positioned themselves somewhat naturally. Aha! So, a dead but fresh specimen being held in midair by tw...

Re: Chrysoperla carnea (common Green Lacewing)

Very nice! I'm curious how this was shot. Aside from the palp stuck to its eye, the subject appears to be in typical live position clinging to a glass sheet that it was photographed through. But I'm having trouble imagining a green lacewing holding still enough to shoot so many frames manually. So, ...

Re: Diatoms - Coscinodiscus marginatus and Eupyxidicula sp.

Really nice!

Am I correct in thinking that only the diatoms are SEM images, while the base, back, and shadows are synthetic?

Re: Zerene and hand-held focus stacking "manually"

Hi, I'm the fellow who wrote Zerene Stacker. I apologize for having overlooked this thread earlier. I load them into Zerene and sort the input files by size, which I take it will also sort them by focus depth. I assume that you're referring to File > "Re-order input files" > "Sort by Scale". With mo...

Re: No sharpness when using mitutoyo 10x (also halo, low contrast)

Mitutoyo 5x (notice that here there are more details on the spider's hairs than on the 10x) I downloaded the full resolution pictures from Flickr and did some study. What I see depends on the scale that I look. Here is a screen capture of Photoshop, showing corresponding areas from the 10X HR at 20...

Re: Diatoms: macro style

A very pleasing image indeed!

I look forward to hearing the story of the modding of your macro setup.

I also note "tilted back 35-40 degrees", so of course I would love to see stereo. <insert begging puppy emoticon here>

Re: Fun with the AstrHori 25mm

I am mystified by the software used here and can not figure out how to move the appropriate 6x image here. If any moderator would care to fix it for me, I would appreciate it. I'll be happy to help, if the problem has not already been solved. At the bottom of the thread I see a "6x adding 26mm tube...
