I concur, a lot of great photos. The dragonfly was my last choice and I almost didn’t use it. I really like the high speed flash photos and would like to work on those. Might I ask what is the trigger used for these type of photos? Sound?
Also I really like the style of sleeping’s photos.
On my water drop pictures I used the cameras built in flash and a wired remote shutter button I made when I first learned about those things shortly after I got my dslr. That and a lot of luck with timing the drop hitting the water.
I use a trigger that I built from a kit, then modified to my needs. I can trigger on sound, electrical contact, laser break-beam, infra-red, or any sharp rise or drop in ambient light level. It also has a variable delay from 3-15 mS.
