Does this require a lot of time or a little time to fill the “pail of water” ie. to let light into the camera?

a. More

PROBLEMS TO SOLVE

Thinking of the water situation…

What would you do if at f/2 at 1/500 of a second you have to change your

shutter to 1/2 because you are trying to blur movement?

Things to think about…

-at f/2 at 1/500 you are the perfect exposure

Going from 1/500 to 1/2 will let __________ light into the camera.

Therefore, you need to let _______ light into the camera with aperture.

Do this by making your aperture _______________.

Move your aperture towards ____________.
