I am trying to wrap my head around using gels.
I know that gels can be used to
- To match the colour cast of the flash to that of ambient lighting. An example would be to use a CTO (change to orange) or a CTS (change to straw) gel to match the flash to tungsten lighting in a room. I would need to set the WB on the camera to Tungsten.
- To enhance the colour of ambient light. An example would be to use a CTO again during a sunset to enhance the sky. The camera's WB would be set to Tungsten. A Caucasian subject would be rendered with natural looking skin tones.
- To give colour effects to a scene. Arts stuff.
What I want to know how the other camera WB presets change the colour cast. I tried playing around with them but Tungsten is by far the most obvious. The others are so subtle, they are hard to make out.
What other gets would be used and to what effect?
Any pointers or links would be appreciated.
