What camera raw plugin for Photoshop CS2 + Canon Rebel T21

I still have the excellent Photoshop CS2 and bought a Canon EOS Rebel T2i. However, the raw files come up in Bridge without picture preview. The file is a CR2 file. When double-clicked, Photoshop 2 opens and gives error dialog:

"Could not complete request because not right kind of document."

  I see that version 5.7 and 6.1 of Adobe Camera Raw Plug in are compatible with this camera. Can I use either plug in with Photoshop 2?

Jim, thanks for the education. I've learned more from you and Noel about what goes on under the hook in Bridge and PS than from all the books I've seen.

"Depending on how you have set your preferences, Camera Raw can be called  by first opening Photoshop and then opening Camera Raw."

Then why not do as Noel does and skip Bridge altogether? I wonder how how Noel does that.

  Still, what format file does PS use when I start editing in PS?


If you mentioned it, I have overlooked what operating system you are working under.  I use Windows.  It's possible to see the files in Windows Explorer.  And if you want to work that way, all you have to do is double click on a file (if you have your raw/DNG files associated with Photoshop) and Photoshop will start but as soon as it is loaded and realizes you have chosen a raw file it will start Camera Raw.  And that is where you make your adjustments to your raw images.

I think the reason you have thought you were editing in Bridge is because if you have configured Camera Raw for full screen there is nothing to indicate that you are in Camera Raw.  But there is the little icon just to the left of the histogram that will toggle full screen on/off.  And if you go out of the full screen mode you will see at the top in the window bar that you are using Camera Raw.

Personally, when I use Bridge/Photoshop, I like using Bridge because (in my opinion) it offers more viewing options than are available in Windows Explorer.  But then that is just my own personal preference.

When a file has been transferred from Camera Raw to Photoshop it isn't in any file format.  The pixels have been converted and loaded into Photoshop memory.  When you go to save the file Photoshop will give you some choices, but I believe it defaults to PSD which is a Photoshop document.

No.

Only one major release of Camera Raw is supported in each version of Photoshop:

CS2 - Camera Raw 3.x

CS3 - Camera Raw 4.x

CS4 - Camera Raw 5.x

CS5 - Camera Raw 6.x

Adobe stops adding new cameras to the older Camera Raw when they release a new version of Photoshop (with a new version of Camera Raw), so without upgrading Photoshop you will not be able to just "open" your files.

They, of course, want some of your money too, and clearly you have some since you bought a new camera.

Adobe does provide, as a workaround, a free tool called the DNG Converter, which you can use to convert your CR2 files to DNG, then Photoshop CS2 should be able to open them.

Noel, thanks for the answer and the link. If I understand you  correctly, I should download Adobe DNG Converter and Camera Raw 3.7  update; then uninstall Adobe Camera Raw 3.7 (how do I do that?), and then  install Adobe DNG Converter and Camera Raw 3.7.

But once I've done that, will Bridge recognize the files and how  will I edit the RAW files or will I have to edit the DNG files in  Photoshop?

                                       Thanks, CMA

Actually, there is no need for you to uninstall Camera Raw 3.7.  All you need is the latest version of the DNG converter.  Make sure you look at the options and choose the appropriate compatibility option so that it will be compatible with your version of Camera Raw.  The DNG file still contains the raw image data, so it cannot be edited in Photoshop.  Once you have converted your images to DNG files you will be able to open them in Camera Raw 3.7, and you will have every feature that version has to offer.  3.7 is really outdated now, and you aren't going to get the full benefit of what you can do with your raw images.  But at least you will be able to edit them as DNG files, and will be able to do as much as that version was/is able to do.
