Thanks but I already have GIMP. I use it for the lens distortion corrections for JPG pictures taken with my Phantom 2 Vision Plus. But for the version I have (GIMP 2) I know it won't import RAW pictures, although I don't know if this is true for the latest version...if there is a later version.GIMP is an open source application that's a Photoshop copy. Not as good as Photoshop but free and plenty good enough. Not sure about the Raw thing but easy enough to find out. Search for GIMP and check it out.
The reason why I want something to open RAW files is that, so far, all pictures I've taken have been .jpg but I expect to be doing work for a client in October that will want RAW pictures but I will need to be able to see what I'm providing.
