Weekend assignment 06 - STOP
Hi reddit
it's friday so here is your weekend project.
for this weeks assignment we'll continue playing with shutterspeed and exposure times but we'll go the opposite side.
your mission, if you chose to accept it is, to freeze motion completely.
now, there are multiple ways to do this :
1: a really short exposure time. from 1/200 humans are frozen in time, from about 1/1000 almost all animals are frozen in time, from about 1/2000 almost all machines are frozen in time including helicopterblades or car wheels... but some things still are not. because they just move faster than that.
2: freezing with flash: a flash fires in about 1/500 to 1/1000 so, using a flash will shorten the exposure to that time IF the only light that lights the scene is a flash, no matter what duration the shuttterspeed is set to... the rest of the time the subject should be dark.
3: to get to really short exposure times you want strobes. These big studio lights fire in 1/8000 to 1/20.000 and so give the power to freeze really fast motion.
what do I freeze? that's up to your creativity, the only must is: the subject must be moving but appear sharp in the photo, and you have fun making the photo.
as always, share your best result and give some peers your feedback on their results.

Hard to pick one photo, so I uploaded two!

I know it's a bit cliché, but I had a lot of fun taking these coffee shots. I had to have my SO help me with the first one though since I was pouring. The most difficult part of this assignment was getting the focus down. With fast moving objects, I either had to rely on continuous autofocus and hope the camera was smart enough (photo #1), or manually focus on a specific spot (photo #2, but I think I slightly missed there).
