A higher ISO setting increases the sensitivity of the camera's image sensor, allowing it to capture more light in low-light conditions. However, this also amplifies the signal, which can result in increased noise or graininess in the image. Therefore, there is a higher chance of getting noise or graininess in the image when the ISO is higher.

When the camera is set to manual mode, it means that the operator has full control over the settings such as aperture, shutter speed, and ISO. This allows the operator to have complete creative control over the image, as they can adjust these settings to achieve the desired exposure and depth of field. In contrast, when the camera is set to automatic mode, the camera itself adjusts these settings based on its own calculations. Therefore, in manual mode, the operator is responsible for adjusting all the settings.

The larger aperture is f/2.8. In photography, aperture refers to the size of the opening in the lens that allows light to pass through. The aperture is represented by an f-stop number, where a smaller number indicates a larger aperture. Therefore, f/2.8 has a larger opening compared to f/22, f/16, and f/5.6.

ISO refers to the sensitivity of the camera's image sensor to light. It determines how much light is required to capture a properly exposed image. Higher ISO values make the sensor more sensitive, allowing for better performance in low-light conditions but potentially introducing noise or graininess in the image. Lower ISO values result in less sensitivity, suitable for well-lit environments. Therefore, ISO is not related to the amount of light let into the lens, the speed of the shutter, or the color of the image; it solely pertains to the sensor's sensitivity to light.

When attempting to get a good exposure, the three settings that should be checked first are aperture, ISO, and shutter speed. Aperture refers to the size of the opening in the lens that allows light to enter the camera. ISO determines the sensitivity of the camera's image sensor to light. Shutter speed controls the amount of time the camera's shutter remains open, affecting the amount of light that reaches the sensor. By adjusting these three settings, photographers can control the amount of light entering the camera and achieve the desired exposure for their photographs.

A fast shutter speed is used when you want to freeze an image in time. By using a fast shutter speed, the camera captures the subject with minimal motion blur, resulting in a sharp and clear image. This is particularly useful when photographing fast-moving objects or subjects that require precise timing, such as sports photography or capturing a fleeting moment. A fast shutter speed allows you to capture the subject in sharp detail, freezing the action and preserving it as a still moment.

Aperture refers to the size of the opening in the camera lens that allows light to pass through. It controls the amount of light that enters the camera and reaches the sensor. By adjusting the aperture, photographers can control the depth of field and the amount of light that enters the camera, ultimately affecting the exposure and the overall look of the image.

Opening the aperture when taking a photo at night is necessary to allow more light to enter the camera. By widening the aperture, the camera can capture more light, resulting in a brighter and better-exposed image. This is especially important in low-light situations where there is limited available light. Therefore, it is true that opening the aperture is recommended when taking photos at night.

A smaller aperture (represented by a larger f-stop number) such as f/16 will give a bigger depth of field (DOF). This means that more of the image, from foreground to background, will be in focus. On the other hand, a larger aperture (represented by a smaller f-stop number) such as f/2.8 will result in a shallower DOF, with only a narrow portion of the image in focus while the rest becomes blurred. Therefore, f/16 is the correct answer for achieving a larger DOF.

The official name of the camera on display is CANON EOS-60D.
