Originally posted by GeoJerry I've been using Photomatix and Topaz a lot lately, but have noticed that the EXIF data is not passed back to Aperture after editing has been completed. Is there a way to fix this problem? For example software to stuff the middle exposure EXIF from Photomatix into the output?
I think that it is likely stored in a separate file which are called xmp files if you use photoshop or lightroom. if they get erased or the program you use can't find it, then all the original settings in raw are lost, and likely the exif information will be gone as well.
not sure what type of file they are in photomatix, but google will likely help
good luck
