My Professor discuss about using flash in photography. They watch a video about the discussion about the different lights such as:
= Photoflood- It is very hot. (2900k)
= Halogen
= LED- Expensive but durable.
= Fluorescent
= Speed light
= Studio strobe
Meaning of TTL and ETTL:
TTL (through-the-lens)- metering is a feature of cameras whereby light levels are measured through the lens that captures the picture, as opposed to a separate metering window.
E-TTL (evaluate through-the-lens)- for CANON users only.
I know the different angle of light (Direction of light) such as:
= Front Light
= Back Light
= Top Light
= Side Light
= Rim Light
Modeling Light- mix of light to the model.
I know some basic tools for flash in Photography:
Hot shoe
Soft Box
Light stand
Light Bouncer
Reflector
Flash Trigger
I know how to clean CAMERA :)
