Canon 7D problem with RAW format

Nima Koochek Shooshtari , Nov 20, 2009; 08:14 a.m.

Recently I have upgraded from Canon 350D to 7D.
First of all I have to say its an amazing camera , but I have a problem with RAW format files.
I took some RAW shots and when I upload them into my computer and wanted to open them in photoshop CS3, the answer was " could not complete your requestbeacuase it is not the right kind of document."
Can anyone inform me what is the problem please? is it for the photoshop CS3 or what?

Thanks in advance

I know they will open in CS4.. What version of camera raw are you using?

Ed Hurst , Nov 20, 2009; 08:25 a.m.

The Adobe Camera Raw (ACR) plug-in to Photoshop CS3 is not directly compatible with 7D raw files. The version of ACR that comes with CS4, if updated to the latest version, will handle these files. Also Canon's own DPP software will process the files. Another option is to use Adobe's free DNG converter to turn your 7D raws into the universal DNG raw format; your version of ACR will handle these DNGs without problem.

You can download the DNG converter here:

Why don't you just download the DNG converter from Adobe - it's free and will convert your CR2 files into DNGs, which you can open and edit with your CS3 program - no need to spend money on CS4 - might as well wait until CS5 comes out!

at present the Canon's DPP software works best on the 7D, I have CS4 and use the Canon software, Adobe should be coming up with an upgrade, use DPP do the adjustments and then go to tools in DPP open in photoshop, will work just like bridge

Adobe have just released updates (beta) for Camera RAW and Lightroom which support the 7D. Check the Adobe website.

The new Adobe Camera Raw Release Candidate 5.6 has the new updated conversion for 7D files. You don't want to use 5.5. Also the equivalent release candidate for the DNG converter and Lightroom should be available as well. There is quite a difference between 5.5 and 5.6 when it comes to 7D raw conversion.

I would advise using the latest DNG release candidate converter with CS3, and not updating to CS4 right now. CS5 should be out soon enough. DNG Converter is free, and I know that upgrading to CS4 now for its marginal gains for a few months would not be worthwhile for me.

I agree with the suggestion to wait to upgrade Photoshop until CS5. Until then do as Ed and others say.
I have found over the years that every other upgrade is usually all you need to do in the Creative Suite/Photoshop programs unless there is some mission critical new feature for what you are doing.
