Setting an aperture priority.
While you can always change the aperture with manual focus adjustments, aperture priority mode is an automated camera setting available on most modern cameras that can help you capture good photos. In aperture-priority mode, the photographer selects the desired aperture and the camera autoselects an appropriate shutter speed. This can be helpful when you need to capture a bunch of fast shots in a consistently lit environment and you don’t have time to adjust your settings. It can also be a good learning tool as, in editing, you can see the corresponding shutter speed your camera selected in certain conditions. Shutter-priority mode, conversely, autoselects an aperture based on your chosen shutter speed. And program or auto mode will autoselect both for you.
Whether you’re shooting on a Nikon, Canon, or any other brand of camera, a mastery of aperture settings — and their effect on your photos — will help you get great shots in different settings and at slower or faster shutter speeds. And if further adjustments are needed in post-production, that’s where editing comes in. Depth of field can be adjusted in post, and if you don’t quite achieve the bokeh you want, you can blur a background to pop your subject. No matter what your goals in photography, a good understanding of aperture will improve the quality of every photo you take.
