I know what you mean, SomethingWicked. I did a couple of pics (The Kiss and Tutoring at Xavier's) on an old monitor that had fallen out of calibration, got a new one, calibrated it, went to my gallery, and just about cried. The lighting in Xavier's I had worked so hard to get just right, thinking I was on a good monitor, was all washed out, and Rose's hair in The Kiss.. well, it had blended beautifully when I did it on the old monitor. Now, if I think of it, before posting a dark image, I add an adjustment layer that ups the brightness to get an idea of what it'll look like on a brighter monitor. Kind of a sanity check. On the "look like night" question, a lot of old movies used a blue filter. Just taped normally, but with a piece of blue cellophane over the lens. You can do the same sort of effect in postwork, or with blue lighting (or even in directly Poser, putting a semi-transparent blue plane in front of the camera). The catch is, and where a lot of MST3K movies screw up, is watch your shadows. If you have high-contrast, dark, very distinct shadows, it's obviously "day for night". Shadows should be lower contrast and fuzzy.
