Mostly the aperture range varies. I tend to stay between F11 and F22. I would say that most of them are sitting between F16-F22.
External flash with cheap fotodiox softbox attachment was used.
The male mosquito shot is the second stacked shot by the way which I manually blended in photoshop using three hand held shots. I remember also hand holding the the leaf the subject was on as well.
I tried to post some of these shots to that forum post btw and I got upload errors saying I have already posted those shots in a different forum. Will look around because I am sure I could just link them. Thanks all.
