I marvel at the simplicity of an icicle, slowing dripping in the warming afternoon. Tough to photograph, though! I had to have my shutter speed fast enough to stop the drop (this bore out when I had to toss the first 30 images). Then I had to change the ISO settings to let in more light, because my highest f/stop on my zoomed-in settings was too dark (toss another 30-40 images...thank goodness for digital). Then I had to time the shots just right...I could see the water run down the icicle (snap) and most shots missed the drop. I was on continuous shooting, RAW+JPEG and could capture about 6 shots before I had to wait for the memory card to catch up.
After about 100 or so shots, I settled on this one. It's a little noisy but the drop is clear!
Shutter: 1/800, f/6.3, ISO 800, focal length 270mm tripod mount
