Hello! I am currently re-designing by photo-workflow and my plan so far is to convert the RAW-files from my Sony camera (which produces Sony's RAW, ARW) to DNG-format (which is Adobe's RAW). I use Adobe's "Digital Negative Converter" tool for that.
I am now testing my new workflow, using Darktable as the tool to generate the JPGs out from the RAWs. While testing, I found one distinction between the original RAW-files from my Sony and the DNG-files which surprised me a lot and keeps confusing me - I couldn't find a proper explanation for it. --> It seems that all my pictures I generate from the converted DNG-files are slightly cropped. Just slightly, but visible. To test and verify that, I exported JPGs from the different RAW formats with darktable. I did not apply any modules to them (so not cropping, changing parameters etc, just exporting JPGs from the RAW data). The JPGs from DNG are slightly cropped. >From what I read, the original RAW-data should be untouched by the conversion tool. It's just the format of the file itself, storage of metadata etc which changes. Testfiles: https://web.fp.ong.at/FPS08962.ARW https://web.fp.ong.at/FPS08962.DNG Further investigation shows that darktable reports the ARW file with dimensions 6048/4024, while it "should" have 6000/4000. Are the extra pixels in the ARW-file kind of a buffer for in-body-stabilization? Where do they come from, and why do they disappear in the converted DNG-file?
