Sometimes.
Most of the things that we measure are in controlled systems (in a laboratory or factory) so it’s generally quite easy to see them. We don’t really have to capture the subjects in this case.
Having said that, we do sometimes work with things like ballistics (e.g. bullets) and there, it’s much more difficult to make sure that the camera takes a picture at the right time. Fortunately, there are lots of clever electronics available that let you trigger a camera to take a picture at the right time, and many of the people that I work with are experts in their particular field, so they are able to help us set-up our equipment around their experiment.

Cells and nanoparticles are really small, so you have to use special mirrors and prisms to see them. Nanoparticles have to diffract the light a lot to show up. So yes, it can be hard, but we have techniques for dealing with that!
