Hi @michaelezra, if possible, can you upload them to https://raw.pixls.us. When uploading you agree that you own the flies and are granting a specific license to them.
I’m not sure if we need another sample, as we already have a DNG file from the 645z (but @LebedevRI can answer for sure). Do you have .PEF files for the 645z that you can share? We’re currently missing those.
Are you sure you’re not trying to get color in RawTherapee or Darktable and posted to the wrong thread (seeing as they’re color checker shots)?
