I have Photoshop CS2, 9.0.2 and I'm still getting 'can't open file because it uses an unsupported color space' error when I try to edit a graphic object from Acrobat. Is there any way around this problem?

The problem is that supposedly this is a bug in the Photoshop program, that is it's not supposed to be happening most of the time. I can copy the photo out of Acrobat and paste it into Photoshop just fine; however this doesn't let me make changes and save the altered picture back into the Acrobat file.
Now if I can copy and paste the picture, why can't I use the Edit Object tool in Acrobat and cause the image to open in Photoshop that way? Wouldn't the photo opening in Photoshop through cut n paste seem to indicate that Photoshop DOES support that colorspace? Maybe I'm missing something...
Ann, if You open a pixel-image in a pdf by alt-doubleclicking it with the Object Touch Up-Tool, then change and save it in Photoshop the image will get updated in the pdf.
But if the image is in an unsupported colorspace that wont work ... its an old problem and I dont know a good solution for it.
One could convert the image in Acrobat into another colorspace (Advanced Print Production Convert Colors) I guess.
I converted the colors in Acrobat and now the image opens in Photoshop without a hitch. :-) Thanks for the tip Christof! I'd change the image in the original program but we usually just get the PDF file to work with.
On second thought it might be better not to convert all the images but only the affected ones by selecting Properties in the PopUp-menu that appears on ctrl-clicking the image with the Object Touch Up-Tool, and converting individually under the Color-rider.
Edit: Though now that Im trying that myself it seems the Rendering Intents arent honored ... maybe Im doing something wrong there.
Any image that contains and unexpected channel name is flagged as an unsupported color space = hence the dialog.
Photoshop is expecting to see for example CMYK, RGB, LAB, Index and Bitmap. If the person who created the PDF placed a Greyscale file or Spot color image, the dialog will come up. Duotones are also affected except Quadtones that have the supported naming convention of Cyan, Magenta, Yellow and Black. Also, CMYK with SPOTS and DCS 2 files are affected with additional channels as well as channels of expected CMYK are missing.
If I had Photoshops source code to change the naming of channels to allow a user to input names with no color values in Quadtones, I could confirm this naming issue on the Photoshop end.
So in conclusion it's most probably a filter problem in Acrobat that is making Photoshop barf.
PS-CS-3 extended and Acrobat 8
...and it gets really fun when a client converts the images upon PDF export and they have placed all kinds of flavors in the doument. yea right.
When I try to edit an object or image in a pdf file I get the "unsupported color space" error using Photoshop Elements 6. If I use Elements 2, I do not get the error. I can open the same pdf file in Elements 6 with no problem. I am using Acrobat 7.0.9. I have tried converting to every possible format to no avail. Anyone here have an idea what is wrong?
