CR2 is Canon's in-camera RAW
CR2 is the raw sensor data a Canon camera writes at the moment of capture. It's produced by the camera's own hardware and firmware — software can read it, but nothing can manufacture a genuine CR2 from a finished PSD.
Looking to turn a PSD into a CR2 file? Here's the honest answer — and what actually works instead.
You can't convert PSD to CR2. CR2 is a camera's own RAW format — it only ever comes out of the camera.
CR2 is the raw sensor data a Canon camera writes at the moment of capture. It's produced by the camera's own hardware and firmware — software can read it, but nothing can manufacture a genuine CR2 from a finished PSD.
Your PSD is a developed, final image. The extra sensor information a CR2 carries — wider dynamic range, full color depth, untouched highlights — was discarded when the photo was first saved, and can't be put back.
CR2 is proprietary to Canon. Even other RAW formats (NEF, ARW, RAF…) aren't interchangeable with it — there is no universal "save as RAW" that produces a real CR2.
Every real RAW file is one of these camera-maker-specific formats, written by the camera itself:
PSD is Photoshop’s native format, preserving layers, masks and effects for non-destructive editing.
