tcurdt Posted July 3, 2019 Posted July 3, 2019 Hey there, I've already in a couple of forum threads about the file size behaviour of Affinity Photo. Unfortunately things still don't quite add up for me. I've got a 10MB NEF RAW file. I've reduced to RGB/8, history is turned off and I also used "Save As" trying to trigger the file streamlining. Still the Affinity Photo file is 112MB. What am I missing? cheers, Torsten Quote
Staff stokerg Posted July 4, 2019 Staff Posted July 4, 2019 Hi tcurdt and Welcome to the Forums, All i can really do is link you do this post which has comments from the Dev team who wrote the Affinity file format and explain how it works. Quote
tcurdt Posted July 4, 2019 Author Posted July 4, 2019 Thanks, @stokerg Unfortunately all the infos I found and read suggested that a "Save As" should shrink the file to a reasonable size. And that's just not the case for me. Any further suggestions? Quote
walt.farrell Posted July 4, 2019 Posted July 4, 2019 I was going to ask if you'd done anything special to the file after Developing the image, but first I decided to try it myself. My 19MB NEF file becomes a 136MB RGB-16 .afphoto file when Saved. I then converted it to RGB-8 (Document > Convert...) and did a Save As, and the saved file increased to 144MB. I then opened the Snapshots panel, and deleted the background Snapshot, and did another Save As. The file size did not decrease; the byte count remained identical. I then exported as a TIFF, without compression, and got a 46MB TIFF file. Loading that TIFF file into Photo, and doing a Save As gave my a 56MB .afphoto file (including the background snapshot). I then decided to delete the background snapshot, and I did another Save As. Deleting the snapshot did not reduce the file size of the newly saved file. The byte count remained identical. (All "Save As" operations were done using new filenames.) All files are available for upload to Serif for analysis, @stokerg, if you'd like them.

tcurdt Posted July 4, 2019 Author Posted July 4, 2019 Thanks, @walt.farrell, I am quite glad it's not just me Your tests exactly reflect my experience. Quote
tcurdt Posted July 28, 2019 Author Posted July 28, 2019 So no further comments? Ballooning files like that is a bit of a problem for the long term. Quote
