Drag RAW results in JPG.
I'm trying to keep my Photos app synced with my Aperture libraries. Basically I open the album in Aperture, select all and drag them into a new Photos album. This works, sort of, but all my RAW images show as JPGs. Going to Edit in Photos shows the "Use RAW as original" is grayed out.
