The Power of ETTL
What makes flash photography so easy is the power of ETTL. (iTTL on Nikons) This function of your flash and camera working together can in most cases, provide you perfectly ‘flashed’ pictures. You simply set the flash to ETTL and choose the shooting mode you want to use on the camera. No matter what shooting mode you choose, your flash will output the necessary amount of flash for a correct flash exposure. No matter whether you choose P mode, AP, SP, or M modes, the flash is in automatic and sends out the correct flash to your subject because its job is to output light based on the chosen f-stop. It does not care what shooting mode you are in because shooting modes only control background exposure.
In this lesson we are going to look at a few more options available on many of today’s state-of-the-art flashes including some fun shooting techniques such as Flash Key, Flash Fill, and Bounce Flash.
