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...

Ok. Good. That does make sense.

I'll experiment with that. I'll add noise reduction to first darktable loop so ZereneStacker has...........better quality tifs to stack with.

Work flow question

On linux I use entangle, ZereneStacker and a Stackshot rail. I make a sequence of raw images. Then I use the Darktable command line interface to create a matching *.tif file for each raw. mkdir tifs for file in *nef do darktable-cli $file tifs/$file.tif done Then I cd into the tifs directory and use...

Pteronarcys Californica -- a large stonefly (plecoptera)

Yellowstone River, Park County Montana, June 2014 Pteronarcys Californica, locally known as the "Salmon Fly" This is actually photographed in a light tent. I brought several stoneflies home along with some willow branches and then staged the shot. This is a focus stack using Helicon Remote, which el...

On quick look, the problem is that your rawtherapee files have 32-bit floating point color. They don't produce any error messages when read by Zerene Stacker, but the results are nonsense, even in the source panel. Try forcing 16-bit color and let me know what happens. --Rik Ok that solved it. You ...

....forgot to mention. The lighting for the two Nikon nikon.NEF files above is not good. This was just a debug session so I didn't take the time to get the strobes adjusted properly, nor the ISO F-stop settings.

Very interesting! If possible, I would still like to receive samples of a couple of tif files that show this problem. It's a well known saying that TIFF actually stands for "Thousands of Incompatible File Formats", but at this moment I cannot think of what could cause the source images to look OK i...

This now has to be a rawtherapee-cli problem. RawTherapee, version 5.3-669-g478e1c0 (this was a recent upgrade) Using lensfun 0.2.8.0 ........hmm. I wonder what lensfun is. I don't remember installing it or activating it. Instead of using rawtherapee-cli -o tifs -p ./now.pp3 -t -Y -c . to make tif f...

Ok will do. First thing tomorrow morning. With fresh brain cells. FWIW before the the Zerene output I got just prior to black was the attached. This has to be ....... I just don't know what to say.

I use studio lighting for bugs and trout flies. entangle and Zerene to control a StackShot rail. Nikon D700 with 105mm macro lens and optional extension rings. I shoot a stac...

With and without light tent

Two fishing flies photographed much the same way with and without a light tent. In both shots the fly is on top of a raised 1/8" inch thick semi-translucent white plastic (Plexiglass) sheet with a slave flash underneath, pointing up, set at its lowest intensity. Two umbrella strobes left and right, ...

Hmmm. Seems to be working now.
With no apparent why.

Sorry for the hassle. I'll keep at it for few days.
