All you need to know about exposure in 7 easy tips

Exposure is a very important part of photography. You need to get the hang of exposure to move forward as a photographer. Here is all you need to know about exposure in 7 easy tips.
A camera's exposure is made up of several parts, each important and unique to what they do. Get to know each part and their function by reading some pointers below about exposure.
1. Shutter speed
The shutter speed is in charge of how long the camera's sensor is exposed to light. Shutter speed lets you take charge of the motion that shows up in your shots. Shutter speeds are shown as fractions and go along with how long your lens is. For example, a shutter speed of 1/100 would be used with a 100mm lens.
2. ISO
The ISO is how sensitive a camera's light sensor is to light. Starting out, use the lowest ISO possible. You may notice when you want to shoot a night scene, you will want to use a higher ISO, but with that digital noise can show up in your photography. You can always correct this during post processing.
3. Aperture
The aperture is the opening in the lens that allows light into the camera. Opening the aperture lets more light in, closing it allows less light in. The aperture is shown as f stops on cameras. The larger the number, the smaller the aperture. The smaller the f stop, the larger the aperture.
4. Exposure triangle
The exposure triangle is made up of the aperture, ISO, and shutter speed. All three of these work together to produce the best possible photos. They each effect how the others react to shots. Take time to get to know each and see how they work together.
5. Low light
Taking good shots in low light is possible, you just have to adjust certain settings on your camera to get great shots. Open up the aperture to let more light in and increase the ISO to get as much light in as possible. Take time to practice and take plenty of shots to see what works and what doesn't.
6. Depth of field
Changing the aperture can also affect the depth of field in your shots. If you are taking portrait photos, use a large aperture so that the focus is on the person being photographed. The background will not be focused to draw the eyes to the person in the picture. This also creates a shallow depth of field.
7. Over and underexposed shots
Overexposed shots are where there is too much light in a photograph. Underexposed shots are photographs that are too dark. Both types of shots serve a purpose, but as a beginner, you want to be somewhere in the middle. Practice adjusting the aperture, shutter speed, and ISO to get the perfect exposure.
