cirlces of confusion--when they are over sized, these are what cause an image to appear not sharp/out of focus (because the light rays coming through the lens have spread too widely before reaching the film/sensor causing the cirlces to be larger and overlap), is that right?
grain/noise in an image is cause by the over sized silver crystals in the film/sensor (that were purposely made larger to allow for the light-sensitive material to be more sensitive to light), is that right?
but just because a film speed may be fast, and appear grainy and not as sharp as a slower film, this is different than if the cirlces of confusion were to cause an image to be out of focus, right?
does any of this make sense??
i know this is really probably not that important --it's just a sudden random thought i stumbled across...
