As a general term, photography means a process or method for generating images or photographs of an object by recording the reflection of light that objects to it on a light-sensitive medium. The most popular tool to capture this light is the camera. Without light, no photo can be made.source
So, photography can be interpreted as a technique or practice in recording the reflection of light received by an object to produce images or photographs.
2. Understanding of Exposure
The most basic thing about photography is exposure, when using the camera's automatic mode the camera completely controls the exposure of images. The camera automatically selects the aperture settings, ISO settings, shutter speed, and a number of other settings. However, automatic mode sometimes will not give the photo according to what we want then it is very necessary to learn exposure. Prince McClinton in his article mentions When we talk about “exposure,” we simply mean the brightness or darkness of a photo. It seems simple enough to take a photo that is correctly exposed (has the proper brightness or darkness), but in reality, it can be quite tricky. Exposure uses Aperture, Shutter speed, and ISO in conjunction to create a properly exposed image.sourceAperture
Aperture is the hole within your lens, through which light travels into the camera body.source
Shutter Speed
Shutter speed, also known as “exposure time”, stands for the length of time a camera shutter is open to expose light into the camera sensor. If the shutter speed is fast, it can help to freeze action completely, as seen in the below photos. If the shutter speed is slow, it can create an effect called “motion blur”, where moving objects appear blurred along the direction of the motion which you can also see in the below photo.source
ISO
In very basic terms, ISO is the level of sensitivity of your camera to available light. The lower the ISO number, the less sensitive it is to the light, while a higher ISO number increases the sensitivity of your camera. source
3. Understand Shooting Modes
Semi Automatic Mode
Aperture Priority (A or AV) Mode : Manually select Aperture and the camera will select another setting (Shutter Speed, White Balance, ISO, etc.) to get the right exposure.source
Shutter Priority Mode (S or TV) : To have full control on Shutter Speed, and the camera will handle the rest of the settings.source
Program Mode (F) : Program Mode is similar to AUTO, in cameras that have both AUTO and Program Mode, the Program mode gives little control or control over some camera features such as flash, White Belance, ISO, and others.source
Full Manual Mode
Manual Mode : Full control and control in determining all setting parameters such as Shutter Speed, Aperture, ISO, White Balance, and others. This mode provides the flexibility of the settings used in shooting. source
4. Learn 2 Basic Photography Techniques
The two techniques are Image Taking Technique (Type of Shot) and angle technique of shooting (Camera Angle).
