Unable to Save as JPG

Software Siril
1

Hello there. Brand new user.
I have watched several tutorials and have attempted to do some learning before using. I am working with a Vespera Pro TIFF image and using Siril 1.40 on Windows.

I followed the workflow as outlined on the tutorial video and came out with a reasonable first attempt at a stretched image. Not great but it looked OK for a first attempt.
Saved the final TIFF file as well as in JPG format.
Opened up the JPG to find an all black image.
Saved the final result as a BMP file and it displays and looks fine.

Yes, I was in linear display.
Yes, I APPLIED stretches after opening the tools and using them.
Yes, the slider on top was far right, bottom slider was far left.
I tried the same workflow again to be sure and made doubly sure to apply the stretches. Same result. Tried a different file. Same result (all black JPG, reasonably good looking BMP file).
I’d like to be able to export the final Siril-processed image as a JPG. I’m hopeful there is some setting that I missed in setting up the tool at the beginning but I cannot find it. Any help would be welcomed.

Same problem here, and it seems that it happens to more people. Also followed all the indications on the FAQ and manual of Siril but no way.

Hello,

We’re not magicians. If you don’t share your FITS image, we can’t reproduce it. Because, no, this affects very, very few people. Otherwise, we would have already received dozens of messages.

So please share your FITS and I will try to reproduce the bug.

We rarely work with TIFF, so possibly they have something special that siril doesn’t read, please share one image

Hi.

Nobody said you are magicians nor said that this is affecting a great number of users, I said this is happening to other users, no more, as anybody can see searching in the web, and perhaps some user with the same problem could have find some workaround.

I share a FITS file with which I have this problem:

Actually it happens with every FITS I’ve been working til now (not many, I’m really new in this) so it’s probably something in my system.

So this is not TIFF but FITS. Thanks for sharing the image.

I opened the image in siril 1.4, saved it as jpg and it’s not black. Am I missing something? Or perhaps it’s a problem only happening with windows?

I did the same on Win11, and the jpg was not black.

Thanks for the feedback. As I said, I suspect of something in my system, perhaps related to Siril installation itself. I have no problem with other astronomical-analysis imaging tools nor image processing software that I use. Could perhaps be related with python? I don’t know. Anyway, I can perfectly live with this. Oh, I tried to save in every other format offered by Siril and all (BMP, JXL, PNG, PPM) worked without problem.
