I notice that a png image rendered to Mplay turns out looking much lighter and brighter than one rendered to disk.

After some testing, I discovered that it was due to the fact that when I “save frame” in Mplay, the “Convert to image format's colorspace” is selected.

Is there a way to automatically convert the image to the png colorspace when I render to disk?

on the mantra rop Images/Output tab, set the Gamma parameter to 2.2

this will write the disk with the gamma applied…however, if you open the file in mplay, it may get the gamma applied again and make it look too bright…if this happens, set the gamma on mplay from 2.2 to 1

Thanks, I will try it.
