Raw.pixls.us questions

Yes, color checker should be fine and it’s absolutelly 100% CC0 since YOU made the photo, not the checker :wink: Just gotta make sure it’s well exposed, no black data along the edges etc.

Maybe some of that would be ok, but I do believe that the text excerpt there should be fine.

As for smartphones & action cams - as long as they can produce RAW files natively i think those might be uploaded. However most of those should be DNGs and therefore should “just work” ™ :wink:

That would IMO create unnecessary overhead for RPU maintainers so no, exif data should be enough.
