    Using a 580 for a master and 550 for a slave.

    I'm considering using a flip-it on my on-camera light and shooting the 550 into a 32" umbrella (bouncing the light), with both set on ettl. The slave would be next to me and about 8ft. high.

    My question is ... if I did this would I actually be getting the benefit of more light OR would I get the same amount of light (since it's ettl) just distributed a bit differently.

    Thanks -

    The exposure levels should be roughly the same, because it's E-TTL...but the light should be softer because of the diffuser accesories.

    That being said, it's sometimes hard to predict what E-TTL will do so be prepared to use FEC or adjust your slave / master ratio.

    When your strobe is off camera, It's usually best to shoot in manual, you achieve greater control and consistency that way.

    You can forgo the TTL function all together and shoot manual with Canon's wireless system, right?
