Exporting as jpeg - colourspace and bit depth


Recommended Posts

I always edit my photos in ProPhoto 16 colour space inside Affinity.  When I export to jpeg, does the colourspace revert to sRGB, or Adobe RGB? does it change to 8 bit? How about rendering intent? I am unclear if this is something I can control.

It will do what you tell it to do in the Export Dialog settings, specifically Pixel Format and ICC Profile for your questions, I think.

Interesting, I never used the export persona, normally I just export from the menu.  It does have a lot of options but it is still not clear to me how the rendering intent is specified.  Normally when going from large colour space to smaller you can specify relative colormetric, perceptual etc. I do not see thiis option in either the persona or the dialog.

I did not mean the Export Persona, but File > Export.
