How can I open a .CR2 file on my MAC OS X 10.5.8 using Photoshop CS4?

[Guest]

Hi all, I'm not overly technical and still learning, I have about 300 x .CR2 files from my wedding which I need to open as we had our uncle do the photography on his Canon camera, I don't know the model. I have Adobe CS4 so ideally need to open them in Photoshop, after searching online there's doesn't seem to be a suitable download for me to use that works so any help would be appreciated instead of sending the files to a professional to open for me. I'm working on a powermac G5 with 7GB RAM, not sure how to search for free space but I've been using CS4 and it's all working fine. Many thanks, look forward to hearing back with any advice

oh and I've troed the DNG converter and it doesn't work, once i've downloaded it it says 'you cannot open this 'dng converter' because it's not the right architecture. '

Which Canon camera model?

Supported cameras and which versions of Camera Raw and Photoshop support them are listed here

I'm not sure what make it was that he used unfortunately, we are no longer in contact with the uncle that took the photos as hes moved away :S

You may be able to figure out what camera it is using this online EXIF viewer:

Try the DNG Converter 6.7 from this page, and see if it works with your older G5 architecture:

Without knowing what camera the raw files are from, you can't tell whether it'll work without just trying it.

i would suggest downloading the Photoshop demo and opening it in trial mode, that will give you the latest camera raw plugin and the ability to work on and save your images out in .psd, .tif, .jpg (i think the trial works for 30 days)

Hopefully the OP has a more up-to-date computer to try that.

OP has OS X 10.5.8.

Photoshop CC requires OS X 10.7+.

Photoshop CS6 requires OS X 10.6.8+

Which is why I suggested the CS5-vintage DNG Converter 6.7 as a possibility.

Understood.

I was responding to the post #5 suggestion of downloading the demo version.
