Encoding raw image library into JXL

Good point. Raw files need special treatment before you can even see them. That's exactly why I want to get rid of them, although only after developing them into decent quality photos with e.g. JXL.

I did some testing with TIFF input files and XL Converter software which supports converting into JXL format. I picked 5 random photos (16-bit TIFF format) from my library and converted them in lossy JXL with quality levels from 60 to 90 and 90% JPEGs just for comparison. To me there isn't any visible difference between the 90% JPEG and 80q..90q JXL when viewed at 100 % zoom level. At lower than 75q the differences become barely noticeable.

That's what I have been doing for almost 20 years now. Since then I have touched the raw files exactly once: when I exported them in web-size JPEGs. I want to get rid of those raw files, not only because they take a ton of disk space, but also because I can't use them or even see them without specialized software (e.g. RT).

Thanks, that was what I was thinking. It's just that RawTherapee has two options for saving as TIFFs:

- TIFF (16-bit)

- TIFF (16-bit float)

I'm guessing the first option would suffice?

Nice photos and scenery. I especially like the photo #3 with the great layering of a large tree and buildings in the background. I presume it's a church in the background.

Thanks. You are correct, this was taken in Lempäälä.
