Aperture and ISO

Aperture is the amount of light that enters a camera. It controls the opening sizes of the lenses. Aperture affects he depth of field because a low f stop corresponds to a larger or wider aperture size, which results in a shallow depth of field. A larger f stop results in a more narrow aperture which leads to a deeper depth of field.

These images are great examples of aperture because it shows the clarity of the focal point, but blurs the background. Its sort of like portrait mode on your Iphone.

ISO, the light sensitivity rating of a digital image sensor.The ISO feature on your camera controls the sensitivity of he image sensor. The ISO affects image noise because the lower your ISO is, the finer the image will look and less noise it will have.

This image above is great image, but it has too much image noise because the ISO was bumped up to 1600 which is why it looks super grainy.

This image is much finer because there is hardly any grain on the image, making the image look higher quality.
