Description

Hi,
please find attached the noise profile of my Canon EOS 750D. It seems to work quite well with some shots I tried it on.

To make the gen-profile script work on my Mac using the homebrew environment I had to change two things. Please tell me if you like an extra ticket for it.
- removing the 'sort V' in one loops of the as the standard 'sort' of macOS doesn't support "version number sorting". I think this is no problem, as the script already created the ISO profiles in order of magnitude, even if the files are not ordered to ISO.
replacing 'pdftk' with 'pdfunite' (from the poppler tools) not really necessary, but I read that pdftk tends to mess up the access rights on a lot of files and has been removed from hombrew, but one could download it manually.

The results don't look good.
Please try another setup. The image should be as much as possible out of focus und should contain small parts of over- and underexposed areas.

Hi, I not at home for another two weeks. Will do a new set as soon as I'm reunited with my camera ;-)

#4 Updated by Simon Erpenbeck 3 months ago

Okay took a bit longer, but now I've got some updated profiles. Tried to shoot outside on a sunny day. Regarding the script behaviour I mentioned above, someone fixed the issues on a recent branch. ghostscript is now an alternative for pdftk and the sort -v is also fixed.

Your presets.json is empty. I don't know how this can happen. Did you manipulate the zip file?
Please upload the correct presets.json

#7 Updated by Simon Erpenbeck 3 months ago

Hello,
sorry no. I discarded my changes to gen_profile.sh when I pulled the new git version. On Line 337 (long awk statement) of the gen_profile.sh there is still the "sort -V". This fails on MacOS and leads to an empty json (don't know why this is crossed out above in my initial text). I attach both files now (the json and the original txt which I kept after removing the rm)
