I'm looking for a countable noun for an act of taking a picture by a satellite, to say for example several "action of taking a picture". I think that word "shooting" doesn't fit here.
I want to say something like this:
This satellite performed 10 [taking a picture acts] over the last day.
I don't want to say "took 10 pictures last day", instead I want to focus on the act itself.
we got corrupted data from the navigation system during 5th [taking a picture act].
Here corrupted data in no way relates to taking a picture. Taking a picture act here just marks a period of time when it happened.
