I promote saving in PNG over JPG for several reasons yet I never gave a warning...

In PSC CC you can use the smaller 8bit option. This create a 256 color output vs the regular 24bit offered under the two other options (checked transparency or no check).

While not apparent at first glance there are significant differences.

Compare the two different save and pay attention to the chairs leaning against the wall on the right of the armchair.

Note the 24 bit file is a link as the size is 29mb so 'unfit for UHH' if reduced.

24 bit = 733,904 unique colors
8 bit = 256 colors
