![]() There are simply too many (millions) for one person to try. I have used most, but not every single one of these products personally. My goal is to provide useful information and sometimes I recommend products that I believe will help you with your photography, but there are no guarantees. Manual exposure is the better choice for nighttime photos and you're usually using a tripod becasue of the longer shutter speeds required. Shooting outside photos when it's dark is also not a good time to use aperture mode. When you're shooting indoor photos with flash as the main light source aperture priority is not a good setting to use. Of course, when you want the fastest possible shutter speed and the conditions are not the brightest, you can open your aperture to its maximum widest aperture to maximize the shutter speed under the lighting conditions you're presented with. For recommended speeds see the article on shutter mode. ![]() Generally for sports, action, and rapidly moving wildlife (including birds in flight) you'll want to set your camera to shutter priority mode and set the camera at a specific speed. Each specific type of sport or speed of the action has a corresponding shutter speed need to eliminate blur from motion. No For SPORTS/ACTION PHOTOGRAPHYĪperture priority is generally not used when you want to use a shutter speed that is fast enough to freeze the action. These include situations where the length of the expoure is the most important setting to control 1. There are times when using shutter priority or manual mode make more sense than keeping your Canon camera set to aperture priority mode. You'll get a nice variety of background and foreground blurring. When shooting macro photographs it's a good idea to use aperture priority and take several different f/stop setting versions of your composition and look to see the different effect you get with each different aperture. In the photo above I wanted to get the entire pistil (center part) of the flower in focus, so I used aperture priority with the aperture set to f/18. If no other camera settings are changed at the same time, you can see that exposure goes up with larger apertures. To help you see how aperture and f/stop number are related look at the diagram below. The fraction 1/4 (f/4.0) is larger than the fraction 1/16 (f/16). That seems up side down, but f/stops area actually fractions. Smaller apertures have bigger numbers and larger apertures have smaller numbers. We use f/stop numbers to describe the specific sizes of the lens opening.į/stop numbers are at first confusing, but are easier to understand if you remember this one thing. Smaller apertures let less light into the camera and larger lens openings let in more light. ![]() ![]() First, we look at what lens aperture is.Īperture is the size of the lens opening when light is allowed to pass through the lens, enter your camera and strike the sensor. Knowing how and why to change aperture settings on your Canon will help you improve your photography and take better photos, and we all want that. This post also includes a Frequently Asked Questions section (FAQ) and a short video from Canon that gives you a great explanation of aperture. This post will help you understand what an aperture setting on your Canon camera is, what aperture priority mode is and explain why aperture is so important to control. Camera settings can be confusing, but this basic guide to Canon camera aperture will help you slice through the confusion.
