Shaw Academy Photography Quiz

Explanation
The image produced by the camera has a size of 5616 pixels long x 3744 pixels high. Since the resolution of the camera is given as 21 Mega Pixels, it means that the total number of pixels in the image is 21 million (21 million pixels = 21 Mega Pixels). Therefore, the given image size matches the resolution of 21 Mega Pixels.

Explanation
The total angle of view of human vision is 130 degrees. This means that humans can see approximately 130 degrees from their central point of focus. This angle allows for a wide field of vision, enabling us to perceive objects and events in our surroundings.

Explanation
Pixels are indeed grouped in vertical and horizontal lines to form an image. Each pixel represents a single point in an image, and when these pixels are arranged in a grid-like pattern, they form the complete image. The vertical and horizontal lines created by these pixels allow for the representation of shapes, colors, and details in the image. Therefore, the statement is true.

Explanation
The mirror is positioned directly behind the shutter in a DSLR. The mirror reflects the light coming through the lens upwards into the viewfinder, allowing the photographer to see the image before capturing it. When the shutter is released, the mirror flips up, allowing the light to reach the sensor and capture the image. This mechanism is what distinguishes a DSLR from other types of cameras, as it provides a real-time optical viewfinder.

Explanation
An image where the highlights are pure white with no detail is considered under exposed. This means that the image was captured with insufficient light, causing the bright areas to lose all definition and appear as solid white. The lack of detail in the highlights indicates that the image is darker than it should be, resulting in an underexposed photograph.
