SceneCaptureComponent2D too dark, or too light

I’m using a SceneCaptureComponent2D into a RenderTarget2D for a rifle scope sight picture. The problem I’m facing is that the result is either too dark or too washed out if I add processing. I’ve tried Target Gamma in the RenderTarget, Indirect Lighting and Gamma in the CaptureComponent processing, but what looks right for some areas in the game looks too dark or washed out in others.

It seems like I need some sort of auto-correct or dynamic processing. Any tips would be appreciated.

Turning on AutoExposure with a MinBrightness of 0.03 and MaxBrightness of 2 has done the trick.

Now I’m trying to sort out how to match the temperature of the capture to the temperature of the scene.
