Photoshop cannot open a raw photo: match the camera to Camera Raw support

Protect the original and narrow the symptom

Keep the untouched camera files and make a separate working copy. Record the full error, camera model, file extension, and Photoshop version. Try a second photograph from the same shoot and, if available, a file from a camera that previously worked.

If only one file fails, investigate that individual file or transfer before changing the entire application. If every photo from a new camera fails while older files work, compatibility becomes a more useful lead. Neither observation proves corruption or rules it out.

Do not rename a raw file to another extension as a compatibility fix. The extension is a label, not a conversion of its contents.

Compare the required plug-in version

Search Adobe's supported-camera table for the complete model name, including its suffix. Read the minimum Camera Raw plug-in column; the Lightroom columns refer to other applications.

Check any model-specific notes. Adobe documents exceptions for some raw modes and compressed variants, so a matching brand name or broadly matching file type is not sufficient. The table is updated as support changes. Adobe's supported-camera list

Find the installed Camera Raw version through the application's About Plug-In information, following Adobe's platform-specific troubleshooting guidance. Then check for compatible application and Camera Raw updates. Keep your editing project saved before updating or restarting.

If the older application cannot take the required update

Adobe provides a separate DNG Converter for backward compatibility with supported cameras. This is a conversion route, not a way to force any new plug-in into an old Photoshop installation.

Install the appropriate official converter for your operating system. Select a small copied sample folder and a separate destination. In Change Preferences, choose a compatibility setting appropriate for the Camera Raw version that will read the DNG.

Convert the sample, open it in the intended Photoshop installation, and check the image before processing a full shoot. Keep the proprietary originals even after the sample works. A successful conversion is not a reason to discard your source archive. Adobe's DNG workflow

If the camera or mode is not supported

The converter also depends on camera support. It is not a universal repair tool for unsupported or damaged files. Follow the camera maker's supported processing route while checking Adobe's support list for updates; do not rely on a promised support date that Adobe has not provided.

For further help, give Adobe Support the exact model and raw mode, installed Camera Raw and Photoshop versions, the error, and whether several files fail. Avoid posting a private client image publicly. This guide is based on Adobe documentation and has not been tested with physical cameras.
