The aperture on your camera is a hole in the lens that controls the amount of light that passes through the camera lens to fall on the sensor. So, how does this light-controlling hole affect your videos? Let’s dive in and learn more! What is the aperture on a camera? It affects how your video looks and even how the tone of your video feels. In optics, aperture is the name for a hole through which light can travel.īut, aperture doesn’t only matter in physics. For many photographers, the aperture is far more important to achieving great pictures than the shutter speed, because it controls the depth of field of the picture, whereas it's more difficult to tell if a picture was shot at 1/250 or 1/1000 of a second.Let’s start at the very beginning: What is aperture? Great question! Aperture is often referenced in optics - a branch of physics focused on the study of light.Depending on your format, tiny apertures like f/16 and smaller will cause you to lose sharpness due to diffraction effects. Shoot at smaller apertures, like f/11 and possibly smaller, for a landscape picture when you want the flowers in the foreground, the river, and the mountains all in focus.Shoot a medium aperture, 5.6 or 8 so the subject is sharp and background is slightly out of focus but still recognizable.Also, you'll probably want to use the largest aperture when shooting in low-light, in order to prevent blur. Set a wide opening, like f/2 or 2.8, to blur the background and have your subject razor sharp.Set the aperture to control both the light and the amount that is in focus, in other words, the depth of field.The aperture is really important to control the picture it lets in the light, and the light is the most important thing for your picture. ![]() Understand why you would want to change the exposure. Longer shutter speed: more exposure, more light shorter shutter speed: less exposure, less light. ![]() If you shorten the exposure (give less light to the film or to the digital sensor), the exposure gets darker. So, if you leave the shutter open longer, you're getting more light to the film or more light to the digital sensor, and the picture gets brighter, or lighter. Exposure or lightness and darkness in the picture is a combination of the f-stop, which is the size of the hole in the lens, and the shutter speed, which is the length of time that the shutter is open.Conversely, for the same amount of water, if you have a small hole in the bottom of the bucket (small aperture), the water will drain out slowly (slow shutter speed)." If you have a large hole in the bottom of the bucket (large aperture), water will drain out quickly (fast shutter speed). A good way to understand it is to "think of a bucket of water with a hole in the bottom.This can be very unnerving, but f-stops and shutter speeds on every picture to get the light right or the lightness and darkness and exposure.If you look at it like slices of a pie, you would get a lot more pie with 1/2.8 than you would with 1/16. ![]() The f-stop is determined by dividing the focal length by the aperture. The f-stop is a fraction the f represents the focal length. The light meter determines what the proper exposure is it all sets the f-stop and shutter speed.
