flash is also artificial light
the major purpose of the flash is to illuminate a dark scene
earlier flashes contained a mixture of magnesium powder and potassium chlorate
the earliest flashes were powered by hand
the flash lamps were replaced by flash bulbs
flashbulbs took longer to reach full brightness
a multi flash camera implements multiple flashes
flash can be used as a main light source
fill flash is used to supplement ambient light to illuminate something close to the camera
bounce flash is a similar technique when flash is directed to a reflective surface
flash can also be a bad thing as it will give off a harsh light
flash also causes red eye effect
flash can irritate most people
flash may also noy be allowed in museums until given the right permit
every flash photo is 2 exposures in 1; ambient light exposure and flash exposure
flash exposure is not affected by the shutter speed
flash illumination is greatly affected by the distance
cameras measure ambient light and flash illumination separately
bounce flash is also diffused light flash photography
when using bounce flash you are re directing the light away from the subject
direct flash will give you harsh shadows
