Thanks for the kind words, Bruce.
The room is fairly well-lit, with 16 4' double tube fluorescent fixtures, and the camera makes up for any deficiencies. It also corrects for the colour temperature of the lighting, eliminating the usual fluorescent green glow. When I get the second level of the layout installed, I'll be adding another 8 to 10 similar fixtures, mostly below the new benchwork to illuminate the lower level. One of the problems with fluorescent lighting is that is doesn't give distinct shadows - with the parts of the layout where the viewer is looking south, this is a good thing, as otherwise the trains would be viewed from the shaded side. For other areas, I have used a hand-held trouble light to represent the sun, which yields more distinct shadows. However, it also confuses the camera's ability to differentiate between the fluorescent and incandescent light. Here's an example, shot by Mister Nutbar (the train is southbound, so this must be an early-morning shot - the quality of the light looks more "morning" or "evening" than "midday", to me.
I like this shot, but the light is coming from behind and slightly right of the camera - in this view, that makes it from the north-west .
The light quality here looks more "midday" to me, but again, it's from the north-west.
This one catches some sharper shadows, especially of the pole and the crossing tower, and, as the light is out of the east, I'd guess it to be sometime between 8:00AM and 10:30AM.
Of course, to simply show a well-lit picture, all of these compass directions are meaningless to a viewer - if I'm taking photos on my own, I seldom bother with the extra lighting, as it often needs to be repositioned for each shot.
