I think Louis Markoya said that it made no *sense* to combine maps other than with altitude. (or something close, anyway) I remember disagreeing with that when I read it too. I see his point, that usign a filter will dilute a color map, or using other combinations will dilute each one's effect. But I can still see a lot of use for it. I haven't experimented with it yet, though (combining other than with altitude). Maybe they do something funny to one another, cancelling or crudding up the image? Don't know. Let me know if you experiement first and find out, ok? Re your 'frosted glass' problem. What color is the object that you have the filter map on? It should be bright white, right? (so that the opaque sections of the filter map show white). I wouldn't think you would need any color map in addition…. –jp–seattle–
