a flash on your camera can be very useful. Most compact cameras though
have a quite unsubtle flash, which does not change its behavior depending
on the lighting conditions. With SLR cameras, things get better.
give an idea of the way the flash changes the photograph you take, I've
taken 3 shots of the same scene, only using different flashing setups.
The images were shot using a Canon EOS350D
digital SLR camera using the built-in flash and the Canon 430EX flash
unit. Just click on the images to get a bigger image.
||No flash used.
||Although perhaps the lighting here is
quite natural, not many details can be seen from the dark objects
(the plant and the candle).
||The internal flash clearly gives highlights on the
front of objects, and also gives a rather ugly harsh shadow against
the background (look at the shadow of the plant for example).
||430EX flash bounce (completely up).
Although using the 430EX flash unit pointing straight
at the scene gives about the same image as the previous example
using the built-in flash, the pivoting 430EX enables you to rotate
the flash to the ceiling.
The indirect lighting gives apparently the same amount of light
as with the built-in flash, but notice how the highlights no longer
point directly back to the camera. Also, the shadows are much softer
now; you can barely see the shadow of the plant for example.
Overall, the lighting becomes softer.

you may want to look into external flash unit, slave flash lights and
