PHOTOGRAPHER that caught the "UFO" bullet

Shutter Speed: 1/8000 sec. ISO 50 F-stop 1.6
Wow! That's like super fast speed cinematic VIDEO!
I don't believe I've ever shot at over 1/2000
ISO has to do with film sensitivity.
Brighter surroundings = lower ISO & Darker surroundings = higher ISO
F-stop is the size of your aperture (like the iris of your eye's pupil), which controls Focal length, thus clarity. Smaller F-stop the more visual information /
light taken in. Think of it like this. Let's say F-1 is your iris wide open trying to gain more information to see in the dark. F-16 would be like 1/16. Since his was small (F-1.6), it took it more and closer info quicker, better, clearer. (thus faster shutter speed) This would blur in background = the farther away, the blurrier.
1/8000 per sec. X 60 secs. = I can't imagine it! Film wouldn't do. Has to be digital or you'd run out of frames before you could let up on the auto snap button.
Hummingbirds beat their wings at around 80 times per second.
Survival Tip: Before you go outside in the dark, turn off inside lights and/or close your eyes for 30 seconds to a minute so they're already or virtually adjusted. Conversely, if going out into a bright surrounding, use some artificial source of light to shine or flash in your eyes for a second or 10.
