What is aperture
Aperture is referred to the lens diaphragm opening inside a photographic lens. The size of the diaphragm opening in a camera lens REGULATES amount of light passes through onto the film inside the camera the moment when the shutter curtain in camera opens during an exposure process. As aperture changes in size, it alters the overall amount of light that reaches your camera sensor – and therefore the brightness of your image. A large aperture (a wide opening) will pass a lot of light, resulting in a brighter photograph. A small aperture does just the opposite, making a photo darker..

Is it better to have a higher or lower aperture ?
There are benefits to having a higher aperture and a lower aperture. It all depends on what kind of look you are going for — because high and low apertures create distinct looks. A higher aperture (e.g., f/16) means less light is entering the camera. This setting is better for when you want everything in your shot to be in focus — like when you’re shooting a group shot or a landscape. A lower aperture means more light is entering the camera, which is better for low-light scenarios. Plus, lower apertures create a nice depth of field, making the background blurry. You want to use a low aperture when you want a more dynamic shot. For example, we use low apertures like (f/1.8) in our Wistia studio to create that classic shot.

Also it is better to have a higher aperture :
- Larger apertures allow for a smaller depth of field, and generally better bokeh.
- Faster/more accurate auto focus, because more light is available to the focus system.
- Much more versatility, because more light falls on the sensor at a wide aperture, which opens up your options in lower-light settings.
- Better image quality. This is a little more complicated to explain, but imagine you have an option between an f/2.0 lens, or an f/8 lens. If you shoot the same scene with both set to f/8, the f/2.0 will almost always be sharper and have less vignetting. This is because lenses tend to get soft when they are wide open, and by stopping down partially you can improve both sharpness, as well as decrease the light fall-off that creates vignetting.
In this series I used all the F stops to show deep depth of field, medium depth of field and shallow depth of field.
