If your camera supports it, the cleanest option is to record RAW and JPEG separately, often by saving each format to a different card slot. Check your camera manual for settings like separate recording or card assignment.

If your camera saves both formats to the same folder, you can still separate them easily after import by sorting or filtering by file type in your operating system or photo app, then copying all JPEGs to a client folder and RAW files to your archive.

Another workflow is to shoot RAW only, make basic corrections after import, and export JPEGs for the client. Then, once the client chooses favorites, do further editing from the RAW files. This avoids managing duplicate out-of-camera JPEGs and keeps your delivered files consistent with your edited work.
