On most SLR cameras, when does the aperture close down to the set value?

Answer 1

Hello Kayla,

I think what you're referring to is "stopping down your aperture." For instance from F8 to F2.8, F2.8 being the wide open aperture that let's in the most light with a smaller focusing area. In DSLR photography you can chose your aperture or FStop in AV - aperture priority mode or full manual. Hope this helps!
