Photography is one of my favorite hobbies. In our multimedia class, I have learned about the different features of our cameras and the exposure triangle.
We learn about two of the three types of the camera which are DSLRs (Digital Single Lens Reflect) and Mirrorless cameras. This two camera processes the light that comes through the lens in different ways. DSLRs have a mirror and sensor to reflect and then capture the light while mirrorless just captures the light that comes with the shutter without traveling through the mirror and the sensor.
Exposure is the amount of light that reaches the camera sensor and there are three things that affect the exposure in photography which we call the exposure triangle, consist of Shutter Speed, Aperture & ISO.

Shutter Speed is the amount of time the shutter is open to permit light in. It is measured in a fraction of second (1/20, 1/500) The longer the shutter speed, the more light can come in through the lens. Besides affecting the light, Shutter Speed also is used to capture the different type of motions well including sports, etc.
Aperture is the size of the lens that let light into the camera. Adjusting Aperture will affect the depth of field (how blurry or clear your background is) Wide aperture has a shallow depth of field (causes the background to be blurry) whereas narrow aperture has a deep depth of field (clear background).

ISO is the control over how sensitive is your camera to the light (the higher the ISO, the more sensitive it is to light which makes the photo brighter). However, increasing too much ISO can cause the photo to be noisy so we should increase it only when adjusting shutter speed and aperture is not enough.
In addition to that, I have learned about the different types of photos including long shot, full shot, medium shot, close up, extreme close up, low angle, high angle, eye level, dutch angle/tilt, over the shoulder and bird’s eye view.
