Lightroom is not required for Color Correction customers, but we recommend Lightroom Classic (from the Creative Cloud suite) and the Smart Previews workflow for the best experience. We currently support Lightroom CC Classic (versions 7 & 8).
If you prefer not to use Lightroom, we can always send you JPG files instead, for an additional $.05 an image. You'll need to upload full-resolution JPEG or RAW files for this option.
Lightroom is not necessary for Retouching services.
We no longer support Apple's Aperture software.
