Ok, to begin with, larger cameras can mount larger flash tubes, and have
space for more battery power to keep them fla****ng. Smaller cameras
just don't have the space, or battery power to accommodate the larger
flash mechanisms.
Some cameras do control the brightness of the flash, usually in concert
with the light metering, and the focusing system. Others don't. Look
for that information in the specs.
P&S cameras aren't designed to take flash pictures in large areas, so
they don't manage well in this application. It is just a matter of
limitations of size, weight, and battery power imposed by their size.
If you routinely take pictures in such situations, then a P&S camera is
probably not for you.
Reviews usually list the flash distances with comments about the usable
range.
