Thank you, Richard, for raising this. In looking at these file formats, it looks like crw is based on ciff, cr2 is based on tiff and cr3 is based on quicktime.
For some file formats we do, application/x-this-app; version=1.0, application/x-thisapp; version=2.0. For others, we create separate main mimes as you've done: image/x-raw-canon image/x-raw-canon2 image/x-raw-canon3 I think we want to keep cr2 as subtype of TIFF and cr3 as subtype of mpeg/quicktime so that those parsers automatically correctly pick them up. Another option would be to subtype cr2 to crw and cr3 to crw, but then add cr2 to a supported format in our TIFFParser and cr3 to our mpeg/quicktime parser. Perhaps Nick might chime in on how we want to handle this. I think we should improve our detection of these at the very least. I found some examples for cr2, if we can get examples for crw and cr3, that'd be helpful. The dropfiles link isn't working for me at the moment. :( Some useful links (I want to document these for me. You probably already know them!)
