While taking portrait or close-up shots, I am sure you would want to keep the subject in focus and blur out the background by choosing a large aperture small aperture value. While shooting landscapes or cityscapes, you might want to have both the foreground and the background very much in focus. This is only possible if you manually choose a small aperture high aperture value.
Suppose you are in a dim lighting condition and your photos are coming out underexposed. If you are shooting in broad daylight and are getting overexposed photos while shooting in automatic mode, you can close the aperture opening.
As the name suggests, Shutter Priority mode allows you to take charge of the shutter speed. Just to brainstorm, shutter speed is the duration for which the camera shutter remains open for the light to enter the camera and ht the sensor.
The slower the shutter speed is set on the camera, the more the light is received by the image sensor. Much less pressure than manual mode! You can adjust the ISO, the exposure, white balance, aperture and the camera will control the shutter speed depending on what you select for the other settings. Using Aperture Priority mode also creates a beautiful bokeh in your photographs, you know that gorgeous blurred effect in the background of a photo?
This is how you get it! A large aperture results in a blurred background or foreground depending on your chosen focal point. If you can imagine the lens inside your camera opening and closing to create a hole, with the large aperture being a completely open circle and the smaller aperture resulting in a tiny hole. Aperture is all about controlling your camera using the available light.
Adjusting the ISO, aperture f-stop and exposure, which are all possible whilst using aperture priority, changes the way your camera reads the environment and tells it how much light to let in when you click the shutter. Exposure: A simple way to increase or decrease the brightness of your image. May 12, at pm.
It does take a lot of the fiddly out of it if your just trying to have fun and get a great shot. That feels like a load off. If you know how to control or adjust these elements, then taking a well exposed photograph will not be a problem for you. In this article, we will focus on understanding the differences between using a wide and narrow aperture, as well as how that choice will alter your photographs. In photography, this term relates to the opening of a lens. When you press your shutter to take a photo, the shutter mechanism opens to let the light in.
Light then hits the sensor before the shutter mechanism closes again. The aperture that you set impacts the size of that hole. The larger the opening, the more light that will get in. Similarly, the smaller the opening, the less light that will be let in. It functions in the same way our eyes do. If we look at a bright scene, the iris in our eyes shrinks, however, if we enter a dark environment, it expands to let in as much light as possible. You can see the aperture in the middle of this lens.

Most modern cameras will allow you to adjust the aperture by changing settings on the camera body, however, some lenses also have a physical aperture ring around their barrel.
Understanding when you will benefit from using a wide or narrow aperture will help you achieve a result that is in line with your creative vision.

When browsing for a lens, photographers generally pay attention to the maximum aperture the lens can open up to as it gives an indication of the faster shutter speeds available for the lens to be able to perform in low light scenarios.
This is because a wide aperture has a larger opening hole, thus it lets more light in. Having a lens with a wide aperture will give you more flexibility but it comes at a cost. While prime lenses have a set maximum aperture, some zoom lenses have a variable maximum aperture. This means that the maximum aperture will vary depending on the zoom range you are using. As we've already noted, aperture is a crucial styling tool in photography.
The aperture allows you to control the depth of field in your images. This gives you more room to be creative because it determines the area that appears sharp in your photos. What this translates to in photographs is blurry backgrounds. Wide aperture creates a blurry background. Photo by: 'Karl Chor, Unsplash'. In what scenarios would we benefit from choosing a wide aperture? People, food, and product photographers will appreciate being able to use a lens that can open up wide.
Being able to create a blurry background is beneficial when you want to isolate your subject, whether it is a person, a coffee cup or perhaps a single flower in a vase.
Once you dial in exposure compensation, you are set to go until it has to be changed again. With light-toned subjects, you will have to overexpose them to maintain the correct exposure. The only difference between aperture priority mode and manual mode in these circumstances is that you will be spending more time focusing on the creation of the photos than you will be on the dials on your camera. To be clear, I am not advocating for not learning how to use manual mode.
For the best results, it is important for you to understand how your camera works in relation to exposure. Using manual mode is the best and fastest way to do that. However, once you have it down, using other modes alongside your knowledge of exposure and how it works will help you and your photos in the long run.
The backlighting in this image created an extremely high contrast situation. By dialing in -3 stops of exposure compensation, I was able to ensure that the issues were dealt with in a series of images with one turn of the dial. Because the camera is now setting the shutter speed for you, the only thing you have to worry about in most situations is exposure compensation.
The only other thing you might have to worry about is if you have the need, or want, to change your ISO. But that is going to be more uncommon. At the risk of repeating myself, but I feel this point really needs to be driven home.
