Flash Fact and Skills

PART 1:

Flash fact #1: Every flash photograph is two exposures in one

Flash fact #2: Flash exposure is not affected by shutter speed.

Flash fact #3: Flash illumination is dramatically affected by distance.

Flash fact #4: Your camera measures ambient light and flash illumination separately.

Flash fact #5: With automatic flash metering, the flash illumination is measured after the shutter button is pressed, and the flash output is adjusted accordingly.

Flash fact #6: Every SLR camera with a mechanical shutter has a maximum flash sync shutter speed

Flash fact #7: (Applicable to modern electronic cameras only) If you set your shutter speed faster than flash sync, or use Av mode with an aperture setting that requires a shutter speed faster than flash sync for proper exposure, the camera will automatically revert to flash sync speed when the shot is taken if a built-in or hotshoe-mounted flash is turned on.

PART 2:

1. Finish this sentence: The further your subject, the more powerful flash you need.

2. No, ambient light would be increased in a long exposure.

3. You can't expect your flash to work out of it's range.

4. 1/200

5. The guide number for a flash is a way of quantifying its maximum output in terms that a photographer can relate to aperture and distance.

6. The lighting is too harsh and flat. You can bounce the flash off of something, like a wall, to fix the problem.

7. It completely eliminates the chance of red eyes and it gives you more pleasing shadows.
