It has occured to me in the course of learning this photography thing, that merely peering through the camera lense lends a perspective to your modeling that you just can't get with the naked eye. Whether you're framing up an entire scene, or just a piece of rolling stock, or a structure, you see things (good & bad) through the camera that you wouldn't otherwise. I'm sure this isn't any eye-popping revelation to Shamus, & the other old pros on this board, but I would highly recommend this to any newbies, or anyone like myself, who hasn't tried the camera before. You don't need anything fancy, just get a 35mm (SLR) camera, & take a look at some things on your layout. You might be surprised by what you see - or maybe by what you don't!
