Photo techniques to simulate late afternoon sunlight

• I used a single 90W halogen flood light shining directly on the train at a very low angle for the sun. I kept this light as far from the train as was practical in my train room (about 12') to make the shadows sharper. Fuzzy shadows are often a giveaway that it's not real sunlight.
• I used a single 250W photo flood bulb with a reflector to simulate the sky light. I aimed this bulb at the ceiling so it would 'bounce' into the scene. I was careful to avoid letting this light shine directly on the scene (to avoid dreaded multiple shadows problem).
• The halogen 'sun' has a color temperature of around 2800K. The photo flood bulb has a color temperature of 3200K (photo flood lamps were made for use with special 'Tungsten' color balanced slide film. This makes the direct sunlight warmer and the indirect (sky) lighting a bit 'bluer'. A good combination for simulating real light.
• By 'bouncing' the sky lighting off the ceiling it was greatly reduced in intensity making shadows very dense. Lots of contrast!
• I set the white balance manually on my digital camera to 2900K.
• I tried to position the camera to take the best advantage of the dramatic lighting and shadows resulting from the very low angle of the sun.

Presto, instant fake late after-noon sunlight!
