Evaluative-Through The Lens (E-TTL) is a Canon EOS flash exposure system that uses a brief pre-flash before the main flash in order to obtain a more correct exposure.

Magic Lantern was originally written for the Canon EOS 5D Mark II [3] by Trammell Hudson in 2009 after he reverse engineered its firmware. [1]
This system is also used on Canon's new EOS system, making the T90 the only non-EOS Canon body compatible with TTL Canon flashes. [5] The T90's X-sync speed of 1/250 second was the fastest Canon had achieved and is better than most other cameras available at the time it was in production.
This is being done in a significantly different way than non-flash 'through the lens' metering. The actual metering itself happens in two different ways, depending on the medium.
