E-TTL vs E-TTL Optical Wireless (multiple flashes) vs E-TTL with radio triggers yn-622c
2 months ago

hello,

i was wondering if is there any difference if i'm shooting with

1. one flash on top of the cam in ettl,

or

2. multiple flashes with one on the cam connected optically with the other flashes

or

3. using a triggers to fire slave flashes example: yn622

what i know : that the flash will do a preflash and the cam will calculate the diff between the ambient light and exp with the flash in different zones....

but what if i'm using lets say 3 flashes!

ok.. lets say no ratio difference were set, or fc, will all flashes fires the same level (amount/power) based on the calculated exposure ?

else how the camera will tell which flash is causing which light in the scene?

best
