Exposure X4 can read RAW files and edit them non-destructively. Here is a list of the camera RAW formats supported in Exposure X4. If you’d like to see support for a camera that isn’t listed here, please email firstname.lastname@example.org and tell us about it.
If you use Exposure X4 as a Photoshop or Lightroom plug-in, then RAW file support does not apply. For plug-ins, Photoshop and Lightroom do all the RAW file reading.
