WHAT IS EXPOSURE TRIANGLE?
What is aperture?
An aperture is a hole or an opening through which light travels.The bigger the hole,the more light gets into camera.The aperture and focal length.The higher the focal the higher the walls of the iris,the less light is available. high walls means that only few light beams will be in focus creating depth. Aperture has a big impact upon depth field. Large aperture will decrease depth of field while small aperture will give you larger depth of field.

what is ISO?
In photography, 'ISO' means the standard system of measurement for how much light a sensor has. We can control the ISO to create an image that is correctly exposed. Not too light not too dark. This is useful when you are either in bright conditions or dark conditions. A higher ISO will make an image lighter and lower ISO will make it darker. however with a higher ISO, the image would be grainy but with a lower number, the image may be darker but more presentable.
What is shutter speed?
Shutter Speed is the only thing between the light that has been passed through the aperture and the image sensor is a shutter. Shutter Speed is a tool foe freezing the appearance of motion. shutter speed is a setting on your camera which controls the length of time the shutter is open. on a bright day when there is a lot of light if you allow the shutter to be open for too long then too much light will get to the sensor. when this happens you end up with pictures that are very pale and almost all white. This is called as EXPOSED.
