This is a big Robber Fly, asilidae, catched an orange winged ant, is possible to see the digestive enzimes it injected in victim body.

This is a big Robber, the photo is with Canon MP-E 65mm f/2.8 macro at about 1.5 magnification (or less) The flash is the 580 EX II bracket mounted.

Crop of the above shoot, it's possible to see the enzimes of the Robber turning the inner parts of ant body in liquid form, noticeable by the bubbles, feeding it almost digested.

Very good study.

A technical question regarding lighting:

What is the reason to use a hot shoe style flash in this instance over a ring flash? Are there instances in which a ring flash is not appropriate, or are they both equally useful for the same shots?

gmazza, with your equipment, how far from your lens are the subjects?
PS. your pictures should be somewhere like National Geographic, they are just absolutely INCREDIBLE!

I simply prefer the bracket mounted flash (not in hot shoe but with a cable mounted in a ball head) I think this is easier to diffuse, allow some directionality in light and I want to keep the frontal part of the lens free as is easier to focus in the subject.

My personal choice :wink: There are many ways to light macro shoots.

Sven

tha working distance for this is about 8cm
