About uploading RAW files to My Photo Stream

RAW files imported into Aperture can be uploaded to My Photo Stream and viewed on your iOS devices. The way the RAW file’s image is uploaded depends on how the RAW file was imported into Aperture and whether any adjustments have been applied.

Note: When you upload a RAW photo via My Photo Stream, an optimized JPEG copy is created and added to the photo stream. For more information, see My Photo Stream overview.
