PHOTO – Day 2 depth of field
To blur or not to blur?
The size of the aperture has a direct impact on the depth of field, which is the area of the image that appears sharp.
The larger the number, such as f/8 (which means a smaller aperture), will bring all foreground and background objects in focus.
f/8 “sees” most like your natural eye.
A small number such as f/1 A small number such as f/1.4 will isolate the foreground from the background by making the foreground objects sharp and the background blurry.
Use the aperture for selective focus, concentrating on a part of the image.
