A critical piece of information would be what camera model the RAW images you're trying to open are from.
Each model camera must be supported specifically in Camera RAW. If your camera is newer than the latest ACR version available for your Photoshop version then you'll be unable to open the RAW files in ACR.
Three solutions are:
Use the latest version of the free DNG Converter from Adobe Updates < http://www.adobe.com/downloads/updates > to convert each RAW file to a DNG and then that DNG will be openable in the older ACR version. You may need to change the ACR-version compatibility setting in the DNG Converter. This solution is free but doubles your storage space if you keep your original RAW plus the DNGs.
Buy Lightroom (which is less than half the price of Photoshop) and continue to use your older Photoshop with it. The adjustments you do in LR are the same as you'd be able to do in ACR (actually more because the newest version of LR and ACR have more adjustments)
Upgrade to or buy the latest version of Photoshop, depending on your upgrade availability.
I personally have both Lightroom and Photoshop and use LR 90% of the time.
My camera is the Nikon D300.
I have Camera Raw 4.0 and I downloaded the DNG Converter as suggested and it
worked - hooray. I'm able to open my images in raw again.
I will be researching the Lightroom purchase as it seems the best way to go.
Thanks again...much appreciated.
…I have Camera Raw 4.0…
You need to update that to 4.6 ASAP.
Besides support for newer cameras, each and every ACR update contains unannounced bug fixes and enhancements, so you should always update to the latest ACR version that will run with your version of Photoshop, which in your case is 4.6.
As a matter of fact, there were substantial improvements between 4.0 and 4.6.
I did update to 4.6 but what do I need to do to activate/install it? I am
just not sure how to replace the 4.0 with the 4.6. Thank you.
Follow the instructions on the download site to the letter. They're different for Macintosh and for Windows.
Essentially, you must replace the 4.0 file in file same location with the new 4.6 file.
To check what version you have, inside PS, use Help / About Plug-in... / Camera RAW and it should tell you the version. It should also tell you the version on the title-bar when you have a DNG or older RAW file open.
I found that - I have 4.0. I downloaded 4.6 and installed it, and it's in a
folder and I extracted the file - re-started the computer but I must be
missing something. I'm just not sure how to replace 4.0 with this new one.
I'll go back online and see if I missed a step. Again, thank you. At least
with the DNG download I can at least convert the files.
O.K. I finally found it - I just didn't read that little document titled
"read me" after the download. You have to go to your C drive to find the
Program Files folder and then navigate through there until you locate the
Plug Ins folder and then there it was...replaced the original Camera Raw
with the new one. And guess what? I can now open images in Camera Raw.
Many thanks to both of you for your help today!
I've seen this confuse people in the past. The installer is just for the Camera Profiles; the plug-in itself must be installed manually.
