Project 1.4
Introduction to the camera and what all the modes and settings do to affect the images.
A, M, S
Aperture Priority (A),
Manual (M).
Aperture Priority (A)
Program (P/Automatic)
​
In Aperture mode, you manually set the lens aperture, while the camera automatically picks the right shutter speed to properly expose the image. You have full control over subject isolation. You can increase or decrease the lens aperture and let the camera do the work on measuring the right shutter speed. If there is too much light, the camera will automatically increase the shutter speed, while if you are in a low-light environment, the camera will decrease the shutter speed.
(M)
As the name suggests, Manual mode gives you full manual control of Aperture and Shutter Speed. In this mode, you can manually set both the aperture and the shutter speed to any value you want. The camera lets you fully take over the exposure controls. This mode is generally used in situations where the camera has a hard time figuring out the correct exposure in extreme lighting areas. For example, if you are photographing a scene with a very bright area, the camera might incorrectly guess the exposure and either overexpose or underexpose the rest of the image which wouldn't make for a good picture.
(S)
In Shutter Priority mode, you manually set the camera’s shutter speed and the camera automatically picks the right aperture for you, based on the amount of light that passes through the lens. This mode is intended to be used when motion needs to be frozen or intentionally blurred. If there is too much light, the camera will increase the lens aperture to a higher number, which decreases the amount of light that passes through the lens.
Program/Automatic
In Program mode, the camera automatically chooses the Aperture and the Shutter Speed for you, based on the amount of light that passes through the lens. This is the mode you want to use for “point and shoot” moments when you just need to quickly snap a picture. The camera will try to balance between aperture and shutter speed, increasing and decreasing the two based on the intensity of light. If you point the camera to a bright area, the aperture will automatically increase to a bigger number, while keeping the shutter speed reasonably fast. Pointing the camera to a darker area will decrease the aperture to a lower number, to keep a moderately fast shutter speed. If there is not enough light, the lens aperture will stay at the lowest number, while the shutter speed will keep on decreasing until it reaches proper exposure.
The exposure triangle
The exposure triangle is important in photography because it describes the relationship between three basic things: ISO, aperture, and shutter speed. Each side of the triangle represents a different exposure setting of either shutter speed, aperture, and ISO These three settings work to balance out the exposure on your image, allowing you to take full control over the exposure of your photos and create a range of effects and styles. Without these three settings, it would be impossible to freeze movement or limit the amount of light entering your camera.
What actually is the ISO?
ISO (which stands for International Organization for Standardization), is a measure of the sensitivity of your camera's image sensor to light. It originated from the film photography days when films with different sensitivities to light were labelled with ISO ratings.
In my primary research I was given a camera and tasked to set it up without much guidance to see if I could work it out and when I went out came some bad looking pictures, daylight images taken with night time settings, so the colour was extremely off. There was even some that was just a picture of the shutter because I changed the shutter speed but after fixing that I continued using the camera to take eye catching photos using my surroundings.
​
The secondary research was like being shown and explained all that you need to know by someone who is experienced in photography and only once I did the secondary research did the primary research make sense and from that came better pictures.
