When we press the shutter button on our camera, for a short period of time the light passes through the lens hitting the sensor staring into an image – actually the process of creating an image is more complex, but for now we just this is enough. So, take a picture means, roughly means capturing the light coming reflected from the scene that we are framing. Exposure Triangle has a big importance in the learning curve of Digital Photography.
