Fundamentals of photography • How the exposure works *postagem em inglês porque sou international* | Blond Fox


The exposure works with the exposure triangle. The exposure triangle is composed of ISO, shutter speed and aperture.

  • ISO: It determines how much light.

Is the sensitivity of the camera.

The photographer uses the low ISO when there's a lot of light in the ambient.

There is three types of ISO

  1. Spot

  2. Centre Weighted

  3. Matrix

  • Shutter speed: Shutter Speed is the action control. 

The photographer uses that higher Shutter speed for objects in action.

It is important to know that the photographer doesn't use a low shutter speed with objects in moviments. 

It is recommended that you use a low shutter speed for portraits.

  • Aperture: Aperture is a fiscal calculation of the quantity of light coming into the camera.

Large Aperture means more light in the sensor.

Small Aperture means low light in the sensor.


Fass lenses are lenses in which the aperture is larger than the others.

These ones give a larger Aperture and more control of the creativity side of the aperture in depth of field.
