Has anyone had experience with using Affinity Photo?
Here is info I copied from the Affinity website on non-destructive vs. destructive workflow. Hopefully it will answer your questions regarding Affinity software.
begin quote "Hi Pete, here's a quick breakdown, hope it helps:
The Develop persona is non-destructive. All tonal operations are done in an unbounded colour space (so no tonal information is clipped). When you click Develop, you then process the image destructively.
However, if you open the develop assistant (that little suit/tuxedo icon at the top), you can change from 16-bit to 32-bit output. This still "destructively" develops the image, but tonal ranges aren't clipped, so you can alter the exposure at any point without losing shadow or highlight information.
Yes, adjustment layers are non-destructive unless you merge them down.
Yes. live filter layers are non-destructive.
Any filters applied from the top Filter menu are destructive. I would suggest duplicating any pixel layers you want to apply those filters to if you want a non-destructive way of using them.
You can create "snapshots" of your work that are stored in the saved document. This allows you to jump between a series of edits and store your progress if you want. See this video on Snapshots for more information.
Regarding the .afphoto document format: You have the option of saving a full undo history (File>Save History with Document). This allows you to re-open a document at any time and step back through all the operations you've performed.
The format saves uncompressed raster information, so yes, it's definitely not a sidecar file ;) . It's worth noting that Photo develops raw images to 16-bit by default, which can produce big file sizes with uncompressed image data. For example, a typical 16MP 16-bit image can be around 120MB in size.
When you first develop a raw image, Photo also stores an initial snapshot so you have a clean copy of your image (again, see the video linked above for more information). This also increase file size. You can delete this before you save your document if you don't need it.
Hope that helps, James" end quote
