Re: Stacking shiney plastic
RE> blurred backgrounds I still have a lot to learn. Much of what I think I know may well be wrong. I do a lot with blurred backgrounds in Post Processing. Most users ply Adobe softwares. I use Darktable and Gimp mostly. Occasionally others. If I make studio macros with a blue or green background it...

Re: Stacking shiney plastic
No I always use DMap, last few years anyway.
I'm not sure why the first attempts were so bad. The light tent made a huge difference, although I also shot that last one at F-16
I need to stick with one photo and work it all day. Until see from worst to best in all possible scenarios.

Re: Stacking shiney plastic
Yes indeed. I got my old light tent out of a drawer and it helped a lot. I don't have a photo of my tent but it's basically synthetic curtain material from a sewing store, stretched over 1" inch diameter transparent plastic tubing (which makes a frame without casting shadows). Yours is an interestin...

Re: Stacking shiney plastic
This was the lowest light setting on my strobes, bouncing off the ceiling. F-16 1/8 second ISO 6400 The high ISO makes it grainy but the narrow aperture seems to have reduced the fuzzy glare, which comes from the frames with least focus in the shiny parts. I tried editing the frames before the stack...

Stacking shiney plastic
I photograph insects and fishing flies. I use umbrella strobes, speed light flash and LCD accent lights. Insects I bring into the studio and then knock them out with ethyl acetate, so they don't move during a stack session. I use entangle, ZereneStacker, Darktable and Gimp on linux for all stacking ...

Re: Weird purple glare on black metal
On a hunch.....the halo-like background shadows above all appeared on the right side of the subject, as if a left side strobe was too bright. So I turned the left strobe down a bit and the right one up to a bit brighter. The halos were completely eliminated. The black jaws of the hook vise still had...

Re: Weird purple glare on black metal
Ok. I tried F5 instead of F8, made the stepping increment 1mm instead of 2 (so 32 exposures instead of 16) and moved the slave speedlight that was illuminating the semi-transparent background from behind so it illuminated the plastic background from the front. I still get some of the halo static aro...

Weird purple glare on black metal
I've been away from photomacography for a year and a half. My synapses are gradually coming back into synchrony after a year and half bout with long Covid. I set up a shot this morning I've done a thousand times in the past but suddenly I'm not getting satisfactory results. This is a fishing fly in ...

Re: Strange ZereneStacker behavior darktable-cli output
Perhaps I found it. In the script loop above the business line ended with 2>/dev/null which suppresses error messages. When I take that away the loop produces an error message for each iteration of the loop: beignet-opencl-icd: no supported GPU found, this is probably the wrong opencl-icd package fo...

Strange ZereneStacker behavior darktable-cli output
I've been using ZereneStacker for quite a few years now. I stack (mostly) photos of fishing flies and the real insects the flies imitate. I might shoot a dozen or more exposures with a Cognisys Rail, using Nikon or Sony (NEF or ARW suffix) I convert the raws to *.tif in a bash loop. Bash scripting w...

Re: Stacking plus exposure blending -- seemed like a good idea
Good answer. I'll work with all of that. Bracketed at each step might be a better direction for me. With big magnification on insects I might use 20 exposures, all the same lighting and exposure. This morning I was thinking about dabbling in commercial real estate photography--where indoor lighting ...

Stacking plus exposure blending -- seemed like a good idea
An experiment occurred to me this morning, which did not work out well. But perhaps it might have If I had only known.........something. I set up what would have been a simple manual focus stack in my office, on a small tripod. I shot 4 focus resets for an object up close, for two intermediate dista...

ZereneStacker default save format
Is this the right forum for software hassles? I'm a ZereneStacker user and fan. I've had it running for many years. Suddenly my installation insists on reverting to "jpeg normal" for a save file format. It used to remember RAW. This could be a file permissions issue but everything I can find, like /...

Trout flies
We don't see many trout fly images here. They are one of my hobbies. Ephemerella Infrequens, known to fly fishermen as the Pale Morning Dun. Real and artificial--with the artificial as a dry fly that floats. The real ones are about 5/16" inch long (not counting tail fibers) or 8mm. Hend held with 10...
