Hi Dave,
Great series of Dove shots and a nice story.
I got some of those 3" square LED panel lights for this kind of thing but find that for insects (e.g. moths) at least, having
that much light so close tends to 'wake them up'.
Also, the amount of light, given the lamp to subject distance when mounted way back on bracket alongside tripod bush, is insufficient to get that much improvement in exposure and it doesn't have the 'freezing movement' benefit of flash. Still, they weren't very expensive and they make great torches.
A ring LED would possibly solve the distance problem, but not the other one.
Have others found this with LED lights?
I'd (quite strongly) suggest going for a flash solution.
Cheers,
