Did I do this right? Dragonfly macro

[Outdoorsman]

Yes, it's already dead. I set it on a white sheet near a window and then cranked the aperture down as far as it could go with the available light. Then I fired a few hits from my flash unit off-camera (not connected) from overhead. It was a pretty dim foggy day, so the camera wouldn't let me get any more aperture. As it was, I set it to about f/27 or so. I think I could use a little more DOF, but who knows? Having never done it before, it was an experiment. I think I did okay. Any suggestions?

I think you did okay, too. I've tried to photograph dragonflies before with disappointing results. For one thing, I can never get the detail in the eyes I want, and for another, they are so big (relative to other bugs) you end up cropping them kind of awkwardly. I think both these problems apply to your photo, but if it were mine, I'd feel like it was a very good start.

Nicely done. I think it looks good. Especially since you burst it with flash which usually adds too harsh a light in situations like this. The light here looks more diffused allowing the colors and highlights to stand out. More DOF would be nice but you have a decent amount here. My only suggestion might be, since you have absolute control of the subject, to shoot from a different angle to eliminate the blurry tail(?) in the background or to pose him/her on a more natural setting.

Hey, thanks guys! Lava Lamp, you seem to be the insect macro guru here, so I really appreciate your comments. And tuna, thanks also for the idea- I still have the little guy, so I should wait for a sunnier day and get the max DOF I can (f/32) and make it look a little more natural. I think this has a sort of clinical look to it- some greenery might just make for a winner.
I keep a diffuser on my flash at all times (see my flash diffuser post in help files), since I hate harsh flash lighting. I tried to keep it a good distance away to avoid badly overexposing. And hey, Provia is the sh!t, is it not? I went to the shop and ran it though the Agfa pro scanner, and the detail I can get out of this slide is incredible. I zoomed in VERY far in PS and found tiny little hairs and dirt that I had no idea were even on the bug. A pro lens would really make the most of this film, but who can afford a pro macro? The Sigma is designed for close focusing, but it's still not a true macro, even at 1:2.
Thanks again guys!!!
