Aperture shutter speed and iso.
The light triangle photography.
Don t worry this isn t a geometry lesson.
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.
The depth of field is a byproduct of this concept.
Shutter speed the amount of time that the shutter is open.
It is measured in seconds.
Aperture shutter speed and iso.
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.
Shutter speed is probably the easiest of the exposure triangle sides to understand.
Hopefully this post has helped explain the exposure triangle photography concept in some detail.
Aperture the size of the opening in the lens when a picture is taken.
I appreciate this is a fairly complex subject and it is something.
Light passes through a hole and is captured on a medium.
The three elements are.
The exposure triangle is a common way of associating the three variables that determine the exposure of a photograph.
Iso the measure of a digital camera sensor s sensitivity to light.
The key part is controlling the amount of light and focusing the light so we get a correctly exposed and in focus image.
This opening is what controls how much or little light can pass through the camera lens and onto the camera s sensor.
