I am on a quest to learn more about lighting, how to manipulate it, use it to my advantage, etc. To that end I would like to know the benefits of using an external flash. How has it helped you?
Thanks for your input :-) |

It adds light.

The great thing with an external flash is the ability to bounce light off the ceiling or walls to avoid harsh lighting and shadows.
this is an example

| Spazmo, that is way too technical for most of us. Break it down and keep it to words of no more than two syllables. With 10 years of commercial photography education you can do it. |

Darn engineers. Using those big words like "light" and "it"

| It does a lot more then just adding light. In the simplest of cases you can do a ceiling bound, this will both remove red eye effects as well as giving you a much more natural looking photo. I use a flash that I can remotely sync to my cameras flash allowing me to place the flash anywhere I want it, this gives me a great deal of control over the lighting of my photos. |

Thanks Spazmo! I would have NEVER figured that out on my own! ;-)
What about with specific types of photography like macro or nature/lanscape shots? I read somewhere that an external flash can help bring out color and details. Is that true? |

External flash is the best thing to use on a bright, sunny day.

Since you asked:
It emits light, synchronized with the opening of the camera shutter at a predetermined intensity, by rapidly discharging a capacitor across a xenon flashtube. The flashtube is contained in a pseudo parabolic reflector that is plated with metal and polished to give a high surface reflectance. The open side of the reflector is typically covered with fresnel-like lens. The parabolic reflector and the lens work to focus and direct the light emitted by the flashtube.
Some flash units allow the lens and the reflector to be moved independently along the axis of the light beam to concentrate or dilute the light beam to provide coverage that roughly approximates the image circle on lenses with different angles of view.
The lens also serves as a protective barrier, shielding the consumer from the potential burn hazard presented by the flashtube and also to protecting the flashtube from damage.
In a typical flash unit, since the amount of light output from the tube is not sensitive to variation in discharge voltage above the threshold required to illuminate the gas in the flashtube, the light output is varied by increasing or decreasing the duration of the voltage discharge across the flashtube. Thus, a brighter flash pulse has a longer duration than a less powerful one.
Ummm, I can go on if someone really wants.

Big time ... helps reduce harsh shadows. And it makes your camera look badasser. Badassest with a battery grip too.
