I am new to the photography world, and I have a canon 40d camera. I recently purchased a canon 430ex flash. I am considering buying an alien bee B400 as well, but my question is whether or not these two lights could work together. I have no idea how to sync the lights so that they flash at the same time if they are both off camera. I know I may need a transmitter and a receiver, but I have no idea what type to buy! If somebody could please give me specifics on what to buy and how to sync the lights to my camera, that would be great! Also, eventually I would like to move to the high key bright white backgrounds. Do you think the 400b would be powerful enough to produce that bright white background? Thanks!
