I took two Canon CR2 files into ON1 to merge with masking to remove a flaw. I exported the result as both a TIFF and a PNG. OK, so the PNG doesn’t show in PhotoLab but the TIFF does but the Lens data is missing. All the other EXIF information is showing, focal length, aperture, exposure time, ISO, etc. Why did it get lost? Would I have to edit the EXIF data manually to get the lens data back into the image?
PS, can that be done in DxO? if not, what would be the best way?
