Lovely shot David good and crisp. I have a few in my back garden pond currently, I have the same problem as you but I have managed a few decent shots.
The lighting looks good, though not over exposed, I may be tempted to reduce the highlights just a tad.
Very nice! That's a great dragonfly rig! Works well with the 1.4X too, if they are posed. Excellent pose and BG. Lovely sharpness and detail. Probably nothing to do about specular highlights except turn them gray.
Thanks for the all the very encouraging comments. It is a great
Dragonfly and Butterfly rig Diana, I have been using a 32mm extension tube rather than the 1.4extender because you are not limited to just the centre spot for a/f. I ususly a/f first and then manually adjust if needed.
