Photography has lately become popular activity in society. Learning photography will be very challenging in order to get a perfect picture. In this modern era, learning about basic photography is not as difficult as you think. You can get a beautiful picture by understanding these three basic things in photography.
Learning about basic photography is started from these three things; ISO, Aperture, and Shutter Speed. Let us discuss these three things one by one.
ISO in digital photography is a camera sensor measurement of the light. In a very basic term, ISO will brighten or darken the result of your photo. If you increase the number of the ISO, your photo will be brighter. If you decrease the ISO number, your photo will be darker.
ISO will be very important when you try to capture images in dark environment. However, there is a side effect when you increasing your ISO to higher number. If you capture images with higher ISO, you will get a lot of noise in your photo. So when you try to take a photo, keep the ISO as low as possible. By keeping your ISO, you will get a nice rich colour and low noise. If you think the photo is still too dark, you can recapture the image by adjusting the Aperture, and the Shutter Speed.
Aperture is a hole inside the camera lens. This aperture controls how much light goes to the camera sensor. You can easily understand how aperture works by imagining this aperture like a “pupil”. You can enlarge and shrink the size of the aperture to control the light that goes to the camera sensor.
This aperture is measured by F-Stops. The scale of the F-Stops starts from F/1.4 – F/22. What you need to remember is a high F-Stop like f-22 means that the aperture hole is quite small, and a low F-Stop like f/1.4 means that the aperture is wide open. As the aperture widens, the F-Stop number gets lower and more light is allowed into the camera and vice versa.
Another thing that aperture can control is the depth-of-field. Depth-of-field is how much of the picture is sharp, and how much is blurry. If you want to take a picture of a person and have the background be blurry, you’d use shallow depth of field. If you want to take a picture of a person and have the background be blurry, you should use a high aperture size (small F-Stop). But if you want to take a picture of a sweeping mountain vista, you should use a small aperture size (high f-stop number).
- Shutter Speed
Learning about shutter speed is quite simple. Shutter speed is the length of time your camera shutter is open. If you want to take a fast moving object or you do not want your image blurry because of the movement, you need to set your shutter speed to a high number like 1/1000 or 1/2000. The length of the shutter speed is vary. It depends on how fast your object is, and also how much light you have. With a high shutter speed, you will get a darker picture and vice versa.
However, if you want to take a picture with a blurry effect on the object, you can set your shutter speed into a low number shutter speed. But, in order to get a great picture with a low shutter speed, you need a steady hand, or you can use a camera tripod.
- High ISO → Brighter Picture → More Noise.
- Low ISO → Darker Picture → Less Noise.
- High Aperture (Low F-Stop) → Brighter Picture → Blurry Background.
- Low Aperture (High F-Stop) → Darker Picture → Sharp Entire Picture.
- Fast Shutter Speed → Darker Picture → Less Blur.
- Slow Shutter Speed → Brighter Picture → More Blur.
Those are 3 basic photography that you can learn as a beginner photographer. You can start practicing to take some picture by applying those 3 basic photography, and learn how much ISO, Aperture, and Shutter Speed should you use in order to get a great photo.
