CPEXIF is a project tool that transfers EXIF data from a Nikon RAW file or a JPEG file to a JPEG file. The software allows for easy transfer and preservation of metadata for photographers and professionals.
CPEXIF is a command line utility, and the usage may vary depending on your needs. For instance, in NEF to JPEG copy mode, you can use the syntax: cpexif [options] source.nef destination.jpg. The available options include --nomakernote and --noisofix which allow you to strip the MakerNote field from the EXIF data and fix the non-standard ISO Speed value respectively. It's important to note that using the --nomakernote option may cause you to lose some information about the equipment and the picture.
In the JPEG to JPEG copy mode, the process is straightforward, and you can use the syntax: cpexif source.jpg destination.jpg. The program copies the whole file segment containing the EXIF data without examining it. This means that data modification cannot be performed, and no options are available in this mode. However, this approach ensures that JPEGs from any digital camera can be processed by CPEXIF.
One of the new features in this release is that it fixes JPEG file corruption with EXIF data larger than 64K. Additionally, an automatic fix for the missing standard ISO Speed field has been added in the NEF to JPEG copy mode. Overall, if you need a handy tool for copying EXIF data between files, CPEXIF is worth considering.
