JPG on monochrome; unlike my GX-7, the GM-1 does not have a customizable curves setting so I am not able to get the higher contrast black and white JPEGs i prefer. So, bit of PP on both LR5 and SIlver Efex Pro 2. The GM-1 is a great, portable camera, with a very sharp kit lens and a great sensor. I highly recommend it.Yes sooc? I am so close to pulling the trigger on this cam.
