Pentax K-5 DNG files not supported anymore

[Hombre]

Hello @agriggio , my first issue on your repo because I’d really like to use ART, however my Pentax files are not fully supported anymore.

Load the file from here ( for development use only ) into the Editor, black points seem to be off. Problem also happens (but less visible) on my Pentax K-1 DNG files, a more recent camera.

thanks for the report, I'll look into it asap!
