I've addressed similar issue not so long ago, so here is what I've got as reply: Am Dienstag, 1.

No idea what Adobe does to the DNG files, but at least camera raw files have (in general) some black borders and otherwise broken areas at the edges that we cut off. Therefore the exported image size doesn't match the raw file size 1:1. Camera JPEGs are a little smaller as they try to adhere to the advertised aspect ratio and probably cut off more to err on the safe side (and make the in-camera processing easier). > Did I miss something? > > Thanks for explanation in advance, > > Timur.
