Grading DPX vs TIFF pros and cons for still photography?

Discussion in 'Digital Darkroom' started by sethbaldwin, Jan 9, 2021.

  1. I like to shoot and process 65mm vision3 stocks like 500t and 250d for still photography, and prefer to work with flat log scans so I have more control in grading.

    As DPX is the standard file format for grading film scans in the motion picture industry, and most still photography labs seem to only offer TIFFs (through my experience). I'm wondering if there are grading limitations with TIFF compared to DPX. I'm trying to stick as close to the motion picture process as I can, but for still photography. I heard something about DPX having better color space for log scans.

    This is an old spec, there isn't anything inherent in TIFF that limits color space, bit depth etc. If your software supports DPX spec, fine. Otherwise I see no issues with TIFF if your software supports that as you desire.
