The question: When I open a raw DNG file in ACR or Lightroom and apply a custom color profile created with a Color Checker and the DNG Profile Editor, will that custom profile remain applied to the file when it is opened by another user? In other words do custom profiles stay with a file?
The background: I was shooting in very weird mixed lighting so I created a custom profile with the DNG Profile Editor. The client wants DNG files. So, how do I ensure that the client gets the custom color profile along with the DNG files? Does the profile become part of the file?
If you ensure to save metadata to the DNG file then the profile will be embedded along with all other adjustments made. But you must make sure to save metadata to the file. You can either choose that option in the Lightroom preferences, or you can press Ctrl/S (Windows) or Cmd/S (Mac) on each image when you are finished or on a group of finished images. Your choice.
