I'm trying to open a CR2 file shoot by a Canon EOS 5D Mark II, but it doesn't show up on Mac OS X 10.6

When I go to file info, it shows me the Device make, Device Model, focal length, ecc. but Dimensions are 0x0 and the photos doesn't show up.

What is happening? You can give a try on this image file

Do you see them in Photoloader? Or what program do you try to use? – bert Nov 25 at 8:00

The file is not corrupted. I downloaded it and it opens fine.

The 5D Mk II has two sRAW formats, which allows a smaller RAW file than the 22 megapixel native size. The sample photo you have linked is a larger of the two sRAW types the 5D Mk II supports, 9.9 megapixel.

Different raw processing software has problems converting the sRAW files though. If you have Photoshop CS4 and a relatively new Camera Raw software. Camera Raw 5.5 mac/win is current, although there is a prerelease Camera Raw 5.6 version on Adobe Labs, you'll be able to open them.

EDIT: If you have an earlier version of Photoshop, you can use the DNG Converter (mac/win) to convert the RAW file into something you can open in an earlier version of Photoshop. However, I think you'll find if you shoot with the full resolution RAW format, it's more compatible than the sRAW formats.

EDIT2: Screenshot of the converted image: http://twitpic.com/qtzyy

I have CS4 and all the updates and it still doesn't open. – NSD Nov 25 at 3:32

Did you rename the file .CR2 after you downloaded it? After I downloaded it, it was named .TIFF – emgee Nov 25 at 3:39
FWIW, this worked fine in Lightroom for myself. Apple's own built-in RAW converter does not seem able to handle these specific RAW files. – Chealion Nov 25 at 6:27
Lightroom and Photoshop both use Adobe Camera Raw to process raw file — which processes sRAW files fine. – emgee Nov 25 at 17:20

Photoshop can't open it either, so I'd say you have a bad file.

I checked it, it isn't corrupt. – emgee Nov 25 at 3:18

Yup, I agree, I couldn't open in preview or the OS or photoshop elements... file is corrupt.

I have a 5D2 and have no problem in 10.5 or 10.6 with raw files from the 5D2 on my macs
