Colour depth determination

How to determine the colour depth of a Affinity photo file?

Create a file with 8 bit colour then add a 16 bit asset, does that convert the 16 bit asset to 8 bit or upscale the 8 bit to 16 bit. If I knew where to look within the app I could determine this myself. I suppose could save it and look at properties but preferring to look in the app itself.

Also what happens if drop 16 bit asset onto 8 bit file….colour loss.?

• use the menu "document->convert", and click cancel instead of apply when done.

• yes: convert the 16 bit asset to 8 bites
• to be clear: only the actual instance/copy of the asset in the document. the asset in asset library stays 16 bit

yes, immediately after dropping, the lower 8 bit gets truncated. If you would place a file the file will keep its own color depth. When you convert the parent file from 8 to 16 bit you would be able to utilize the placed file with 16 bit color depth
