Re: Photographic primers?

Roger:
Here's what can be done using modern digital autofocus equipment for steam locomotives and vintage rolling stock:

The thing to remember is, it's all photography. He'll get good exposures 95% of the time using aperture priority, plus intelligent selection of small lens openings for depth of field, versus large lens openings to freeze action.
The other thing to remember is exposure overrides. If the subject has important shadow areas, it's time to overexpose by 1/3 to a full stop. If there's a locomotive against a huge, bright sky, 1/3 to 2/3 stop overexposure would help out. The ability to 'chimp', preview shots in the camera's LCD or using the camera's histogram if it has one, will let you correct on the spot for another picture of stationary subjects, or for the next shot of tomorrow's train.
All ISO settings should be as low as possible to keep digital noise low, yet high enough to give fast enough shutter speeds to hand-hold without a tripod. Most small-sensor cameras provide noise-free results at ISO 50 or 100. They're usually OK at ISO 200, and really deteriorate for ISO 400 or higher. A tripod is a way around this problem if shutter speeds are fast enough to freeze the action if that's what you want.
Any camera will require him to dig in the manual to discover how to set these modes. It's sometimes very helpful to go to the manufacturer's web site and download a PDF version you can search for specific words and topics. 

Hope some of this helps.

Thanks, Jim. I'm sending these suggestions and links to me mate.
