Title: Aperture Priority.
Of course I had to photograph this piece of Slap Art… had to happen!
So what is Aperture Priority?
Aperture Priority Mode (the symbol of ‘A’ or Av’ on your camera’s dial)
Aperture Priority allows you as the photographer sets the aperture that you wish to use and the camera makes a decision about what shutter speed is appropriate in the conditions that you’re shooting in.
So to answer the question “When would you use Aperture Priority?”… the answer is simple, when you as the photographer want to gain full control of your image in regards to Depth of Field (DOF). If you want that silky smooth shallow DOF you’d select a large aperture (for example f/1.4) and let the camera choose an appropriate shutter speed. If your goal is an image with everything in focus you’d pick a smaller aperture (for example f/22) and let the camera choose an appropriate shutter speed (generally a longer one).
In addition, Aperture Priority allows the photographer to force the camera to operate the lens at its optimum apertures within its aperture range for a given focal length of the lens… or to state it another way it allows you to have full control of your lens and push the ability of that lens.
And last but not least, this camera mode is extremely helpful in low light situations or in situations where light is unstable. Think concerts, theatre, and even outdoor environments.
So there you have it… now you know, and knowing is half the battle! G.I. Joe.
