The Light Triangle Photography

This opening is what controls how much or little light can pass through the camera lens and onto the camera s sensor.

The light triangle photography.

The key part is controlling the amount of light and focusing the light so we get a correctly exposed and in focus image. Aperture shutter speed and iso. Hopefully this post has helped explain the exposure triangle photography concept in some detail. Don t worry this isn t a geometry lesson.

Aperture the size of the opening in the lens when a picture is taken. The three elements are. The exposure triangle is a common way of associating the three variables that determine the exposure of a photograph. For example moving from a shutter speed of 1 60 s to 1 30 s will add a stop of light because the shutter will remain open twice as long.

I appreciate this is a fairly complex subject and it is something. Aperture shutter speed and iso. To double the amount of light we need to double the length of the exposure. This exposure triangle concept refers to how large or small the opening is thru the lens as you can see in the above illustration.

It is measured in seconds. The depth of field is a byproduct of this concept. Shutter speed the amount of time that the shutter is open. Light passes through a hole and is captured on a medium.

Shutter speed is probably the easiest of the exposure triangle sides to understand.
