Different ways of focusing while using a camera

AF –

AF or auto focus automatically does it for you so you don’t need to worry about it and can make it quicker and easier to take photos.

MF –

MF or manual focus means you have to do this yourself and can take more time, however, if you are good at doing this then you may come out with a better outcome than the camera would for you.

what is focal length

The focal length of a lens is the optical distance (usually measured in mm) from the centre of a lens and its focus. This determines what you “see” when using a camera. This can be visualized in the image below.

What is aperture

Aperture in photography is the opening of the camera lens, which is related to the amount of light that passes through the camera lens to the image sensor. The aperture mechanism in the lens that allows more or less light to come in. This can be seen below.

What is depth of field

Depth of field is the distance between the closest and farthest objects in a photo that appears acceptably sharp. This is represented below.

Photographer who uses depth of field in their work – Ralph Eugene

Ralph made his living as an optician, born in 1925 and died in 1976. He was a member of the Lexington Camera Club and pursued his passion for photography outside the mainstream. He experimented with various strategies including multiple exposures, motion blur, and other methods of photographic abstraction. Two of his series are particularly concerned with focus and depth of field, both stretching the expressive potential of photography, film and cameras when looking with the ordinary world. Some of his work can be seen below.

This experiment clearly represents how aperture effects an image.
