Hi Laurie
Expensive from the point of view that Roy is using 5 standard flash guns
(around $500.00 each), but most camera manufacturer's speed-lites are capable
of such speeds as this is how the flash regulates output. Greater power (for
longer distances) results in longer flash durations and less power (for close
up work) results in shorter flash durations.
Larger species such as the Osprey featured would require longer shooting and
flashgun distances, which is convenient, since their movements are slower, and
birds such as Hummingbirds, featured below, require faster flash durations, but
are more predictable as to position, due to attraction to a feeder. this allows
close in flashguns operating at peak flash durations, because they are so
close. A cheap way out is to buy small cheaper flashguns and bank them together
to get the lighting output you require, while retaining high flash durations.
Some very notable Australian photographers have opted for this set up in the
past.
You can get away with less flash guns, but run the risk of dark shadows in some
parts of the image.
The type of set up Roy is using is shown in a similar set up utilised by Arthur
Morris in, the following url
