Here is an image.  This part is light gray, but you'd never know it from any of the screenshots.

The surface facing the screen, even though there is a directional light pointing right at it (I even tripled the intensity of it just to get it to show as light as it does).

Is there a way to get this shading to not be so extreme in both light and dark?  While rotating the part the surfaces flash between light and dark, just a tiny adjustment can alter the color drastically:

Top surface is white, the back surface is close to the actual color.

Part rotated just a few degrees, top surface is now black.

I've been working in "Hidden lines removed" mode just to avoid this annoyance but now I need screen shots and there's no way to rotate the assembly into a position that doesn't look terrible.  I have played with the light intensity and position for 4 hours now and just simply cannot get all the features to show clearly.

Is there a fix for this?  I searched all morning, which is how I figured out how to adjust lighting, but seems like no matter what I do I can't avoid large pure white, and large dark black areas.

Any help is appreciated.  Thanks in advance.
