Often when I post-processing my photos taken out of my camera through numerous softwares, the resultant photos’ EXIF data would be lost. There are many occasions whereby I myself need to study the EXIF data again. And giving the pain of losing the EXIF data, viewers can’t study the photo if they want to later.
Maintaining EXIF data would be a good idea for the above said reason. But, while we maintain the EXIF data, we should make sure that the data shown in EXIF is correct.
For example, after a photo goes through Photomatix (HDR toning software aka photography porn as labeled by some people, hahah, but that’s out of our scope here anyway :D ), EXIF data will be lost. We won’t want to have the shutter and exposure value because the resultant photo are created using multiple exposure but we are still interested on the type of camera used, ISO or the focal length, yes?
Here’s how
Yes, it’s unfortunate so many apps mess with the EXIF data. But here is a workaround:
Load one of your original (LDR) images into Photoshop. Then load your HDR/Tone mapped/edited image. Select all of the latter, then paste (as new layer) in the former. Flatten and “Save As” with file name of your choice. Image will be the the HDR/Tone mapped version but with the EXIF of the original version.

or
you can also use jhead (http://www.sentex.net/~mwandel/jhead/) to transplant the exif header with this command “jhead -te source.jpg target.jpg”. sure, the exposure info is inaccurate, but other useful info remains.

Are you using Firefox?
If you do, you can easily view a photo’s exif data by viewing the file’s properties. EXIF data will be available after you install an add-on called FXIF
