...and here's a closer look at one of the images
on this occasion I didn't have time to wait around until the damselfly's colours had fully developed (it can take several hours) but here's a different, mature, individual for comparison.
and, again, a closer view
Finally, a view of my rough and ready 'field studio' (if that isn't too grand a term for it)! I'm using white Perspex with a flash positioned behind it and a macro flash attached to the lens. I found the trickiest aspect is keeping the Perspex held vertically but settled on a combination of a Plamp and a couple of bamboo canes which seemed to do the job nicely.
All images were taken handheld using a Canon 60mm macro lens.
