wk 6 Camera Use: Flash

Today looked at the flash - Caryline took us through the various ways to use flash.  Speedlights sync with aperture, they read the light and chose the settings which would suit the light readings.  The output will correspond to the reading of the camera.

Direct flash

    • this is when your light source in placed in front of your subject.  The result is very harsh light and photos appear quite raw.   Good to use in the daytime as you would a reflector to fill in shadows
Here is an example of a shot taken before and after using direct flash

Bounce flash

    • Can be used inside, where you can bounce light off the side of walls, ceiling or behind a subject
    • Can use a piece of white paper if you do not have a bounce attachment
Here is an example of a shot taken using a bounce attachment
f/5.6, 1/60, ISO 100 - Taken without any flash

Diffused flash using half moon

    • Used to diffuse light
Here is an example of a shot taken with a half moon over the flash one taken at 1/60th and the other at 1/200th

 Under/over exposing a background

 Here are examples of under and over exposed backgrounds
This is an example of an over exposed background, where the subject and background are in the sun.

f/18, 1/100, ISO 100 - Taken with flash and over exposed
f/13, 1/50, ISO 100
This is an example of an overexposed background taken in the shade and the background
f/5.6, 1/125, ISO 100
 This is an example of an underexposed background.  Although there are other people in the background, because the subject is lit up, they the main focus

f/5.6, 1/200, ISO 100 - flash and under exposed
This is an example of underexposed background.
f/8, 1/200, ISO 100

Flash and blur

This is done with longer shutter settingsThe flash goes off at the end of the exposure, freezing the action at the end.  This feature allows for ambient light to be recorded and is often used when shooting bands with lighting in the background.

My favourite photos are the flash and blur ones.  We had heaps of fun shooting these, i wanted to emphases the movement more, which you can see in the first photo the camera picks up Cecilia's arm and face.  We started using colour which was awesome.
