General Question Lighting Effects Regarding Earth's Terminator

Oh yes it does. If you have a bad monitor, and tweak the settings so that it looks OK on that, a screengrab can look very different on other people's systems.

I think I'm about to learn something -- I had always assumed that screengrab software took the image data either from a dedicated video card's memory, or from the part of main memory that stores video or image data in the case of older systems without a separate video card -- so, could you please explain how the monitor fits into the scheme? I always thought that the monitor's picture settings had nothing to do with the image data that gets stored in memory.

Monitor has nothing to do with capturing a screenshot. It will however throw you off in the terms of the quality of the screenshot. What he is saying is, if you monitor is not set up right, or quite different from someone else, you think you are seeing something that isnt really the case. So you take a screenshot, give it to someone, it will look different.

Yes, you are quite right, and I know that a monitor's settings have nothing to do with grabbing a screenshot -- a monitor is, after all, an input device, not an output device (in terms of sending data back to your computer) -- I was just trying to keep an open mind in case there was any possibility of learning something I might not know. As for the remainder of your statement, this is why I started this post in the first place -- to compare notes with others.
