My $0.02 -- 

As a part of my job, I take a lot of photos, both indoor and outdoor 
using both digital and flash.

My guess is that some of you are getting poor quality on closeups 
with your flash due to "blow-out." First, don't use any digital zoom 
as a previous poster correctly suggested. If your camera has 
a "macro" setting for sharp focus on close-ups, use it. Using a 
digital zoom only forces you to blow up the pixels, which destroys 
sharpness and detail. Then, back off your distance to the subject. 
Most camera flashes operate off a sensing unit -- some are on the 
front of the camera (a little red window or circle) or inside the 
camera through the lens (depends on camera).

I won't go into great mechanical detail because it works differently 
in digital vs. film cameras, but the principle here is the same. In 
taking a flash picture, when you press the button, the shutter 
opens. The flash sensor holds the exposure (holds the shutter open) 
and keeps the flash lit until it senses that enough light has hit 
the subject to get a proper exposure. This happens in a fraction of 
a second. (That's why people in the foreground of a two-row group 
snapshot are often better illuminated than those to the rear. The 
sensor takes its reading off the front row. Or the subjects are too 
far from the camera. Most flash units on non-professional cameras 
have a range from only 4 to 14 feet -- check your owner's manual. 
Cameras, like computers, are stupid, but very wonderful if told how 
to do things.) And if someone is very close to the camera or a 
subject is wearing white, it may shut down the shutter prematurely 
and result in an underexposed (dark) photograph.

The background lightness/darkness and color will also impact your 
exposures. Since it costs nothing to burn digital film, do some 
experimenting. Or manually shut off the flash and use properly 
positioned room or spot lighting. Best results come with the camera 
locked into a tripod and either set to trip off a timer or with an 
extension trip. Locking into a tripod keeps the camera from moving 
and blurring the photo as the exposure will most likely be longer 
than with a flash and it is very hard to hand-hold a camera still 
for slow exposures. If you have Photoshop or a similar photo editing 
program, you can use incandescent or florescent lighting and adjust 
the colors with Photoshop. Incandescent (light bulb) lighting has a 
yellowish cast that our brain changes to white. Most florescent 
bulbs also add a tingle of color, usually blue. The color of the 
lights will also change the color of your trains -- a teeny bit.  
Film or digital captures what it sees, including yellow or blue 
light. But using Photoshop to alter the yellow or blue back to white 
will also (this is MAGIC) return your trains to their proper color!

Or if you have to have perfectly true colors, you can spend a few 
bucks and buy special photography bulbs that screw into a regular 
lamp socket. But make sure to diffuse the lighting by bouncing it 
off a white posterboard to soften the shadows.

If you are a scaler and want the photo to look realistic, use only 
one slightly diffused overhead light source positioned as "The Sun." 
And by playing with your camera's depth of field (if so equipped), 
you can really have some fun.

Good luck
