Hummingbird Multiple HS Flash questions
Greetings:
I am looking forward to Linda's guide for hummingbird photography, but in the meantime I have a few questions someone may be able to answer regarding setting up a high speed flash system with multiple flashes. Assuming a 4-6 flash set-up with one or two of the flashes used to light up the BG...
1. Assuming you set them manually at 1/30th or 1/64th power, and triggering them wireless (in my case using Canon master/slave), how fast can the flashes recycle? Put another way, can they keep up with 8-10 fps?
2. If using an xsync at say a 200th, the flashes at fractional power will be what freezes the hummers wings. Is there any reason why you cannot set the flash(s) aimed at the BG on full power, thus maybe getting by with only one flash at the BG?
3. In a similar vein, while I suspect it is a bad idea to try and incorporate 3rd party or older flashes using an optical slave as one of the main subject flashes (because of a possible delay in firing), is there any reason why you can't use a flash with an optical slave for the BG lighting? It would be great to be able to make use of one or two of my older flashes in this set up.
Thanks!
