Question by dream catcher: Define Aperture-really quick question?
ok, I know what it is I just have a quick question about it- When you “leave the aperture open” does that mean you are using a higher number or lower? or when “you use a wide aperture”
thanks so much 🙂

Answer by Fishmeister
Wider the aperture, lower the number (and vice versa.)
Strictly speaking the aperture is always ‘open’ whether it is f/1.4 or f/22. But wide open would be the lowest possible number (the widest aperture) the lens could allow at that particular focal length.

Think of it this way. The aperture numbers are actually fractions, that is the size of the opening over the length of the lens. Thus f2 actually means 1/2 or one half. f16 means 1/16 or one sixteenth.
