One of the easiest ways to improve your photography is to have the field of field depth in simple terms, the distance of your photo between the object closest to the focus and the farthest away. Aperture Priority Mode is just the tool you need, and the best way to learn how to use it is simply to experiment with it.
But first: what is aperture?
By controlling the aperture setting, your camera lens controls how much to capture the image you are shooting. It works a bit like an eye pupil: the pupil dilates more, is lighter and is inserted into the brain for image information processing.
Measure the size of the photographer’s f-stop size – for example, f / 2, f4, etc. Contrary to what you might expect, the larger the number of F-stops, the smaller the aperture . Thus, f / 2 indicates the opening of a lens larger than f / 4. (Think of the number as the sum of the numbers: a higher number means a larger closure.)
Uses aperture priority mode to control field depth
The size of the aperture works with shutter speed to determine the depth of field, which can make or break your photos. Imagine a landscape shot where the first few inches of the image are sharp or a picture of a chair where it and its background are in equal focus.
To select the aperture priority mode, look for A or AV in your DSLR or advanced point and mode dial at the top of the camera . In this mode, you choose the aperture, and the camera then sets a suitable shutter speed.
Tips for shooting in aperture priority mode
When shooting a landscape যা which requires a wide or large depth of field to keep everything in focus – select an aperture near f16 / 22. When shooting such a small object as a piece of jewelry, however, a narrow depth field will help to remove vague and distracting details from the background. A small depth field can also help to draw a single image or draw objects out of a crowd. An aperture between F1.2 and f4 / 5.6, depending on how much the object is, would be a good choice.
It’s almost all very easy to forget the shutter speed almost completely when you focus on your aperture . Generally, finding a suitable motion of the camera will not be a problem, but problems can occur if you want to use a deeper depth of field without much available light. This is because a wide field depth uses a small aperture (e.g. f16 / 22), which gives very little light to the lens. To compensate for this, you need to choose a slow shutter speed to make the camera lighter in the camera.
In low light, this means that the camera will pick up the shutter speed which is very slow because the camera is held without blurring. In this case, the most common solution is to use a tripod . If you don’t have a tripod with you, you can increase your audio to compensate for the lack of light, which will then push your shutter speed Just be aware that the more you push your ISO, the more noise your image will make.
