Thanks a ton guys! I certainly am not much of a model railroader... but I can use a camera (a little...LOL)....
I actually run a photography business on the side along with the job that actually pays me...LOL
As far as technique... one thing I have learned is to use a little more of a telephoto when shooting these shots... it compresses the depth of field a bit and gives a much more realistic effect when you are dealing with lower than 1:1 scales... also with shooting so close (minimum distances on telephoto lenses) you have to deal with using as small of an aperture (large depth) as possible...especially in dealing with night shoots... so what I did is shoot bulb.... and had a person paint the scene with a light and then also paint the areas that a headlight would normally show while dim... it takes a little trial and error but you can really work into a decent shot...
