I just purchased a Canon EOS 7D. I filled 2 Sandisk 4GB CF cards and went to download them. I tried opening them on 2 separate computers and got the same message in both Photoshop CS2 and CS4: Cannot open this file because it is not the right file type. It is a CR2 file so I'm confused as to why it wont open.
I received a disk with my camera for installation of the following: EOS disk utility, Picture Editor and Digital Photo Professional. I installed all the programs and now can only open my images with those editing software. Even in those programs I can edit the images, but i cannot save them in any file type that I could also open them in Photoshop; it will only let me save in PSF files.
Any suggestions?

Update your RAW converter file from Adobe. Your computers are not recognizing because the camera and RAW files are newer than your software.
Go here if running windows - http://www.adobe.com …duct=106&platfo​rm=Windows (external link)

CS2 does not support your 7D. I believe CS4 does but you might have to update your ACR TAW converter. In PS, look under "Help" and click on check for updates.

I'm not sure if CS4 supports the 7D Raw files or not, but as was said, it's easy to check for an update -- start Bridge and go to Help/Updates and the utility will check for you.

A couple of brief points:

First, you are mistaken about Digital Photo Professional (DPP) -- it has two ways of producing a "Photoshop-friendly" image. After you are done with whatever processing you want to use DPP for, you can use the Tools/Transfer to Photoshop function and it will open the image in Photoshop as a "tiff" although a file won't be saved unless and until you Save it in Photoshop.

Or, you can use the DPP File/Convert and Save function and DPP will give you a few choices for jpeg and or tiff file type.

What you need to understand about DPP is that it was designed to process/develop Raw files, and as such does not "write over" your Raw images, so that doing a "Save" does not work the way it does with normal image editors. The way of getting images converted into usable image files is either through Convert and Save, Batch processing, or Transfer to Photoshop.

One other method of bringing a Raw image into CS4 is to use the Adobe DNG converter and convert your Raw CR2 files to DNG (digital negative) files. The DNG format was designed by Adobe to be a "universal" Raw file format. There are only a few Raw apps out there that support the DNG format (DPP does not, for example) but the Adobe Camera Raw plugins as well as Lightroom will support it.

So, if the CR4 ACR update doesn't work with your 7D files (and it certainly won't work with the newest cameras) what you will want to do is find the Adobe DNG converter for your CS4 version of Camera Raw -- I believe it's 5.x. So you will convert to a file that is CS4/ACR5.x-compatible.

Know, though, that a 5.x-compatible will not work with your CS2 ACR...

CS2 can not handle the 7D RAW files, but CS4 can as long as you update ACR to 5.7. click for PC (external link) or click for Mac (external link). Also, you can do as Tony suggested - Bridge/Help/Updates.
