As part of a scene I have a white diffuse surface with some black icons on it. Right below it I have the same icons in white on a black surface.
The difference between the white and the black A's becomes even greater the smaller it is on the rendered image. Top is rensered at a higher resolution and scaled down, bottom is rendered at low resolution:
Currently the only way I can think of working around this issue is rendering at a higher resolution and scaling down the final image. This is fine for this example, but for the scene I'm working on render times are already high and I really don't want to increase the resolution.
Is there any way I can fix this and have both render at an equal thickness? Is it just a product of how the Cycles works? Is there a setting that can compensate for it? Or am I doing something completely wrong? The only possibly related question I found was this unanswered one here.
