I am a very new photographer with a D90. So far I really like it but it is clearly smarter than me. I have the Mastering the Nikon D90 book (which hooked me up with Nikonians.or ). I am also in a beginner photography class at fife photography where the husband/wife team teach the various classes (http://www.fifephotography.com/lessons/) in Oklahoma City. I am reading the book and trying to absorb at least one or two salient points (my brain is mush at the end of the workday). I cannot figure out how to keep the LCD display on my camera "lit" or "on" for longer than a few seconds. As a newby, I need/want to have my LCD "on" for longer so I can read, understand, and absorb the displayed data. Can't find it in the book. Any help on how to extend my "light-up" time would be appreciated.
