Cameras should have a third shutter button position. halfway: prefocus all the way: fire pushing as hard as you can: “goddamnit, no matter what mode you’re in, open the shutter RIGHT NOW and take a picture with the focus you’ve got and the light you’ve got”.
I was standing in the narberth train station. It was lightly snowing.
Along the middle track comes a cargo train running around 30mph (pretty fast for cargo), being pushed backwards (i.e., the engine was at the back of the train).
the frontmost car was just a pallet - nothing on it, just a flatbed. not so unusual, right?
except that standing on the pallet was a man in a leather flight suit, foot to head, with goggles.
Feet spread and braced, arms out wide, shouting “aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaahhhhhhhhhhhh!!!!!!!!!!!!!!!”
Looked like he was having the time of his life.
anna points out that switching to manual focus accomplishes this. my point is that I’d like to not have to fuss with anything beyond just jamming the shutter as hard as i can when i see something like that going by me at 30mph.
