In the past I've been using another tool (ExifUtils) for transfering GPS-data into my Canon Raw images (CR2). This seemed to work fine as all programs I am working with had no problems, but after using exiftool now I realized that this had removed the CR2 headers in the EXIF-data. Unfortunately I have no backup of the original images.

My question is: Does anyone know a way to bring back the Canon CR2 headers?

I have tried things like "exiftool -all= -tagsfromfile CorrectHeader.cr2 -all:all corrupt.cr2" and manipulations with HEX-editors, but without success.

I would be very glad to have a solution for this, cause a lot of my images have this problem.

Many thanks in advance
