What is Aperture and Why is it Important in Photography


    What is aperture.

    What Does Aperture Do?

    • Aperture controls the amount of light that can enter the camera.
    • Aperture controls the “Depth of Field” this means what we perceive as in-focus before and after the field.
    • Aperture is written F-stops.

    Aperture is the opening or closing of a diaphragm or iris inside the lens. The is the called, Aperture and the number associated with the opening is written in as an F-Stop. The whole F-Stops are written as F-2.8, F-4, F-5.6, F-8, F-11, F-16, F-22. Just like with shutter speeds F-Stops will be shown in 1/3rd stops on the camera. We just use whole F-Stops when teaching the process.

    Just like shutter speed aperture controls the amount of light that can enter the camera. The second function of aperture is “Depth of Field.” “Depth of Field,” controls how much we see as in-focus before and after the area you focus on. This area is called, the field. Aperture is usually the part of the exposure triangle that most confuse. That is because the widest opening lets in the most light, like on the left above, has the smallest F-Stop number F-2.8, and has the shallowest “Depth of Field.” The aperture on the far right lets in the least amount of light, has the largest F-stop number F-22, and has the widest “Depth of Field.”

    Pros and Cons of DSLR and Mirrorless Cameras

    If you have not heard, the DSLR market is on its way out and the Mirrorless market is the future. The main issue with the switch from DSLR to Mirrorless has been the mount change with Canon And Nikon. Yes, you can use an adaptor mounts to convert old Canon and Nikon lenses to work on the new mirrorless mounts. If you are using Sony no worries because they only make Mirrorless camera and nothing has changed.

    I have a Facebook Group called, “Learn Adobe Lightroom, Photoshop, and Bridge.” I created this group because I get a lot of questions on YouTube that are hard to answer unless I can see the issue. This will allow a place you can ask questions, and more importantly post images and videos.
