I am trying to open a file that a photographer told me was a RAW file. On the CD he gave me, it said it was a cr2 file so I renamed it as RAW.
This is from a Canon dSLR and is probably an 8 Mpixel file from either the 1D Mark II or the 20D (I have the Mark II and that's the suffix for its raw files). You shouldn't rename it, it's not in the same format as the Adobe RAW format but instead it's the actual sensor capture from the digital camera and needs to be opened via a RAW converter.
When I try to open in PhotoShop 7, it says that the "specified image is larger than file".
You cannot open this file in Photoshop 7 for raw conversion ... there was a raw plugin for PS 7 but it hasn't been updated for a long time and won't open the ..cr2 files.
Please HELP!!!
If you have access to Photoshop CS then you can open it with that by double-clicking in the File Browser. I think you need the rev 2.2 or 2.3 plug-in for this file, I'm pretty sure the original plug-in won't open it since it came out prior to release of either the Mark II last spring or the 20D in September.
If the file is from the Mark II you can download for free the Phase One Capture One program demo and open it using that converter but if it's for the 20D then I don't think the current C1 program for a PC opens it, just the Mac version. The version supporting the 20D is supposed to be available "soon", like "any day now".
You might also be able to download for free the latest Canon software for raw conversion and convert with that.
If you know someone with CS or the Canon raw converter or Capture One just ask them to open it and save as a tiff and send that to you ... this might be the easiest way.
