Here is one of my strobist shots. This diorama had a hand painted foam core backdrop that was lit with a CTO gelled Speedlight. Two additional Speedlights, one to light the "sunset" on the rails (gelled) and another for fill light (hotshoe) were required. A ceiling reflector completed the setup. The headlight intensity was brought out during a long exposure. Except for the momentary blast of flash this image was shot in near dark conditions.
The models are 1:87 scale on a 20x30 inch diorama.
Very nice! Makes me want to bring out my N scale and take some more shots.
