The aperture settings on a camera control the volume of light that reaches the film, as a high F-stop number is best used for brighter light situations and a lower F-stop number is suitable for lower lighting. Set the correct aperture for the best exposure with advice from a professional photographer in this free video on photography.

Hi, I'm John Budden with Shutter Priority Imaging Center. Basically what we're going to talk about right now, is we're going to talk about aperture's. The first thing about aperture is it's the way we control light through the film or XC/CD imaging sensor, and it's the volume of light. How much light it is. What this is, is this is a lens right here. What I'm going to do is I'm going to show you how the aperture controls through the lens. Basically, there's a diaphragm in this lens that will close down, the camera closes down during the exposure, just like so and it will control the volume. How much light we're regulating to the film or an image sensor. What we're going to do here is there's a couple different ways, how to set aperture on cameras. What I'm going to use is a Pantech's Film Camera and this camera actually has an aperture ring, just like what we showed right here and what you can do is you rotate this to the proper aperture ring or the volume of light you want striking your film or imaging sensor. The other way to do, the other way to set aperture on a camera like that, on this, would be to set this into automatic and then use the rear thumb wheel here and you can control it electronically. When you do, control it electronically you'll see on the top display and also typically you'll find it in the viewfinder on most cameras. The reason why you use aperture for amount of light coming in the camera is to control your exposure and by, most cameras have a built in light meter that will tell you when you have a proper exposure. The brighter the light, typically the higher the FStop number will be. The lower the light, the lower the FStop number will be.
