ETTL-II Data
« on: December 14, 2015, 07:44:51 AM »
Has anyone been able to figure out what is actually sent over the hotshoe for ETTL for a while, and havnt really been able to find much. Ive got a bit of a lighting project i've been working on.

I just googled "canon e-ttl protocol" and found several promising results.

The last time I looked around, the best source was bill grundmanns blog, and he last updated anything in 09, just today, I found this http://staff.www.ltu.se/~joborg/ettl/ how ever that is looking like ettl 1 as apposed to 2.
