Lens 103

What are “stops”, f/4 is referred to as a stop. It allows 2x the light than f/5.6, which is twice f/8…confusing right?

You can memorize the series of full stops: ƒ/1  ƒ/1.4   ƒ/2   ƒ/2.8   ƒ/4  ƒ/5.6  ƒ/8  ƒ/11   ƒ/16   ƒ/22   ƒ/32   ƒ/45   ƒ/64

Or find a chart like this:

F-Stop Chart - How to use Aperture in Photography

Some cameras allow changes to the aperture in a variety of increments, starting from full stop to one-third stop. The Depth of Field (DOF) changes as you change the aperture, the bigger the aperture the shallower DOF (more Bokeh, or blur); the smaller the aperture the DoF gets wider.

Enough for now, but you should have a basic understanding of the f Stops.

Thanks for reading, keep on shooting, and, as always I look forward to your continued support.
