403Dann Posted July 21, 2015 Share Posted July 21, 2015 Just purchased AP, and have been going thru the video tutorials (which are helpful so far.) When opening a RAW file Making adjustments is fairly intuitive. ( )My question is when I'm done editing the RAW file to end the session to I click on the DEVELOP button (top right corner)? If yes, are the adjustments permanent (destructive) to the original RAW file? If yes, please advise how to make non permanent edits to the original RAW file. Do you see a RESET button in your future (ala LR)? Quote Link to comment Share on other sites More sharing options...
totoff Posted July 21, 2015 Share Posted July 21, 2015 As far as I understand you will be prompted to save your developed file as a new file - so it's kind of non-destructive. Quote Link to comment Share on other sites More sharing options...
coranda Posted July 21, 2015 Share Posted July 21, 2015 I'm sure it's non-destructive to the original raw file as it makes no sense to actually edit the photo site data in a raw file. Clicking Develop, I expect, creates a pixel image from the raw file. Raw files don't contain RGB pixels so it would be difficult and unnecessary to apply edits to the raw data in the original file.

403Dann Posted July 21, 2015 Author Share Posted July 21, 2015 Thanks totoff & coranda. I'll drill a little deeper. I did a save, which gave me a file with an Affinity Photo file extension name that was 6 times the RAW file size. So obviously I need to learn a bit more.

JimGoshorn Posted July 21, 2015 Share Posted July 21, 2015 It increases in file size because it goes from basically a black and white image and gets converted through a demosaicing process to a color image with 3 channels. Quote Link to comment Share on other sites More sharing options...
403Dann Posted July 21, 2015 Author Share Posted July 21, 2015 Thanks Jim. I won't even to pretend to understand what you said. :huh: At the end of the day, if all AP files sizes are multiple times the size of the RAW file, it eventually becomes a storage issue/concern.

JimGoshorn Posted July 22, 2015 Share Posted July 22, 2015 The image is recorded in the camera as something resembling a black and white image (think single channel). The demosiacing process converts the image by splitting up the original data into 3 separate color channels (R,G,B) which when combined create the color image. So in basic terms, you multiple the amount of data in the RAW by 3 (it's not exactly 3 but that explains the concept) since it's being split up. totoff 1 Quote Link to comment Share on other sites More sharing options...
