Description

I recently bought this point and shoot camera that had RAW output and I'd like to help get it fully supported in DT. I just uploaded an image to https://raw.pixls.us/ and I'm happy to take as many more pictures as needed.

What other pictures do I need to take to get everything else supported (WB, noise profiles, lens distortion corrections, TCA, etc)?

Thank you!

However for darktable, i will need one slightly overexposed raw per each ISO level that can be set in camera, including any sub-ISO steps, and high-iso expansions if any. Please try to take such a pictures so that all the 4 edges of the images (the whole perimeter) is well-exposed, it really helps to find the proper crop.

What other pictures do I need to take to get everything else supported (WB,

For wb, actually that one raw already contains all the presets.
The problem is, at least for the Canon EOS M5, those are not presets, but they are somehow different each time, so i don't know if it makes sense to have them.

noise profiles

but that article is somewhat outdated. please put that into separate issue

lens distortion corrections, TCA, etc)?

These are lensfun problem, i'm not really familiar with that.

I've attached a picture at every ISO level that the camera would let me select. I used program mode, so it automatically changed the aperature and shutter speed to maintain my +1 exposure compensation. I'll re-take photos of something else if it would be better.

It'll take a few posts to upload all of the photos here (10 files/post limit and I can't put them into a single .tar.gz since the maximum permitted size is 48.8 MB). Is it preferred to upload them like this or do you prefer having the sets uploaded to another website?

Uh, oh, please don't upload them here, put them in one(!!!) archive, upload it somewhere, and just add a link.
I should have stated that in the first place.
