Saving JPG with EXIF Information

Postby RayCx » Fri Jun 13, 2003 11:17 am

This may have been covered, but I cannot find it in the history.

I wish to edit my DSC JPEG files in Photosop, then save them whilst retaining the EXIF details. This is in order that my camera will accept them back again, so that I can tote them around.

The Photoshop 9 manual does not give any details, do I require a pug-in?

Any assistance welcome.

Photoshop 6 and 7 let you open and save JPG files while retaining their EXIF data. So simply open your JPG files, edit them and save them again as JPGs.

The only problem is to choose the sufficient JPG compression ratio. Usually using the Maximum setting is best. But you can try saving them at different compression settings and see which setting produces the same file size as the original image.

Saving JPG with EXIF Information

Postby RayCx » Fri Jun 13, 2003 7:30 pm

Thanks Harald,

First, it is Photoshop 7 of course.

I tried this and reloaded the results back into my camera but it would not read them. hence the query.

Looking at the file headers with a programming tool, I see that the original file started 'Exif MM ...' while the saved file starts 'JFIF..HH..UExcif MM'.

The EXIF information is still there in the file, but the camera software possibly reads the altered header info and rejects it.

I shall experiment some more, maybe with an alternate editing program.


Any other info always welcome.

You could try different options in Photoshop's Compression dialog e.g. Basline or Progressive etc. Maybe one of the option creates a file that is accepted by your camera.

Paint Shop Pro 8 also saves the EXIF data now. You could try it.
