Light passes through a hole and is captured on a medium.
The light triangle photography.
Hopefully this post has helped explain the exposure triangle photography concept in some detail.
Don t worry this isn t a geometry lesson.
To double the amount of light we need to double the length of the exposure.
I appreciate this is a fairly complex subject and it is something.
Shutter speed is probably the easiest of the exposure triangle sides to understand.
The depth of field is a byproduct of this concept.
The three elements are.
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.
It is measured in seconds.
This opening is what controls how much or little light can pass through the camera lens and onto the camera s sensor.
The exposure triangle sounds like the name of a complex spy novel but in reality this is the term used for the three fundamental elements of exposure.
Each of the three aspects of the triangle relate to light and how it enters and interacts with the camera.
Aperture shutter speed and iso.
Shutter speed the amount of time that the shutter is open.
Aperture the size of the opening in the lens when a picture is taken.
Aperture shutter speed and iso.
The exposure triangle is a common way of associating the three variables that determine the exposure of a photograph.
