Chamber Photography Posted November 7, 2017 Share Posted November 7, 2017 Hello everyone. So im new to this program and loving it so far. But what im not understanding is why are saved files so large? Im working on a simply raw file edit of a portrait I took. Only 1 adjustment layer and I did frequency separation. Saved the file as both psd and afphoto, some how both files are about 400Mb. Is there a fix to this? Quote Link to comment Share on other sites More sharing options...
Staff Lee D Posted November 8, 2017 Staff Share Posted November 8, 2017 This is typically because developed raw images are processed to 16-bit - it offers more precision but increases file size exponentially. Before you save your .afphoto file, you might try the following: Go to Document > Colour Format > RGB (8 bit) to convert the image to 8-bit and save file space. Go to View > Studio > Snapshots to bring up the snapshots panel. You should see an initial "Background" snapshot. Delete this as it's essentially a backup copy of your image that takes up file size space. Quote Link to comment Share on other sites More sharing options...
R C-R Posted November 8, 2017 Share Posted November 8, 2017 Adding slightly to what @Lee D said, this article discusses how different cameras typically store RAW files using both compression & lower bit depths to save file space. Decompressing & 16 bit conversion during the development process would result in a lot larger file than the size of the RAW file suggests.
