If in your workflow RAW -> PNG -> JPEG, the fianl JPEG file include
Exif, this must mean than Exif are in PNG (:=)))
try exiftool foo.png for ex in a console.
But, i'm suprized... You canot see Exif in digiKam ?
Note : i always use PNG in my RAW workflow everyday. Exif is visible in digiKam.
Note2 : I have implemented PNG metadata writting mode on the fly in
current Exiv2 library (next 0.18). This is want mean than you will be
able to record/update all digiKam metadata as it's done with JPEG
(using Caption and Tags for ex.)
