Thanks to help from several on this forum I thought I was making good progress, cruising actually, in processing many pictures and converting them to B&W. I’m using darktable 4.2 in scene-referred mode and seeing the benefit of the sigmoid module.
That said I was too premature in thinking I was able to make my way around darktable. Below I list three problems that have blocked me completely. The manual, excellent in other regards, isn’t of any help in this matter. I’ve even reinstalled darktable expecting that’d get me over the potholes but that didn’t help either.
Issue #1:
I’d process an image, go into lighttable, export, double-click on image, see the “film roll” at bottom of darktable window, click on next image to process…
After successfully doing that with several images I found facing not the next image but darktable’s gray middle panel that says there are no images in library, nothing to view/process, etc. However I had already added a library earlier and processed a subset of images and am ready to process the remaining. I can’t see the film roll at the bottom of darktable window, etc.
If I try to add the same library darktable says the images are already added. However I’m not able to see them to continue processing them.
Were I to close darktable, restart it, or reinstall it and try the same library darktable puts up the first image in the library with crazy artifacts. See screenshot.
Clicking on that image doesn’t open up the film roll at the bottom like I had when I was originally processing the images. I can’t see the other images in the library.
Per the screenshot the “Raje Set 2” had 153 pics. I’ve successfully processed about 50 already. I hit this snafu while about to process the 51st image.
Did I do something wrong? Did I click on some tab or icon that threw me into this situation? Is this a known bug? Can I go back to where I was and continue processing the remaining pics? How do I do that?
Issue #2: issue is the fact darktable no longer recognizes pics taken by my 55mm Nikkor 2.8. It used to. Now it chokes on Lens Correction on every image taken by that lens requiring me to manually pull up the list of Nikon lens and choose the 55/2.8 before proceeding with the other processing. Is this a known bug? What is the workaround, if any?
My appreciation for your comments and help.
p.s. kudos to pixls.us for maintaining drafts of the posting. I was about to send the above, the mouse and keyboard froze, I had to reboot…had given up on typing everything again but was delighted to see pixls maintained the draft intact! I believe darktable is at the root of the mouse./keyboard freeze. Earlier versions of darktable caused the same issue…I thought I might be over that with 4.0 and 4.2…but perhaps not…for what it’s worth I run Windows 10…That’s issue #3.
