Q&A: What is the purpose of an aperture in a CAMERA?

Question by : What is the purpose of an aperture in a CAMERA?
I don’t understand.

All that I understand is

F. 28 (means the shaft is small) f 2.1 (the shaft is really big) always the opposite.

Big, more light, little, less light. That’s all I understand.
But people are saying there’s more?
What the hell is depth of field?

Are you saying that
if the aperture is F26 (so the shaft is small)
the object in the front will be in focus the background will not?

Best answer:

Answer by word
you’re close, but opposite..

F26 the subject and the background will be in focus

f2.1 the subject will be in focus, and the background will be blurry

  1. if your aperature is at 3.5-8 you most likely will have a short depth of feild and the object close up will be i focus and everything else out of focus. just practice using aperature priority(av) if you have an slr

  2. actually its the other way around the smaller the hole the more thats in focus so at F26 a lot will be in focus but at f1.8 someones whole face wont be in focus there is a lot more into it but depth of field is how much is in focus basically so just remember smaller the hole the more thats in focus
