Copy EXIF data from one image to another

Problem

You have one image with EXIF data and you would like another image to have exactly the same EXIF header. One such situation arises when you create jpg images based on raw images, but the software (for example, Adobe Photoshop CS) does not copy the EXIF data into the jpg.

Keywords

EXIF, data, information, copy, header, between.

Solution

Use ExifTool by Phil Harvey. (Windows users may get lucky by first installing the Perl interpreter from ActivePerl.)

Say you want to copy the EXIF header from file a.crw to a.jpg:

exiftool -TagsFromFile a.crw a.jpg

If you don't want to copy the Orientation field, then run:

exiftool -TagsFromFile a.crw --Orientation a.jpg
