Exposure is the amount of light a digital camera captures when taking a photo. A cameras aperture, shutter speed and ISO also affect exposure directly, but mostly they allow us to control how each photo looks. Shutter Speed Shutter Speed is the only thing between the light that has passed through the Aperture and the image sensor is a shutter. Shutter speed is a powerful tool for freezing or exaggerating the appearance of motion. Shutter speed is a setting on your camera which controls the length of time the shutter is open. Shutter speeds can go from very small fractions of a second, to several seconds long on most cameras. On a bright day when there is a lot of light, if you allow the shutter to be open for too long then too much light will get to the sensor. When this happens you end up with pictures that are very pale and almost all white. This is known as being called over Exposed. Aperture Aperture is the 'opening in the lens.’ When you hit the shutter release button of your camera, a hole opens up that allows your cameras image sensor to catch a glimpse of the scene that you want to capture. The aperture that you set makes a difference on the size of the hole. The larger the hole, the more light that gets in and the smaller the hole, the less light that gets in. Aperture is measured in ‘f-stops’. ISO ISO measures the sensitivity of the image sensor. The lower the number, the less sensitive your camera is to light and the finer the grain. Higher ISO settings are generally used in darker situations to get faster shutter speeds. For example an indoor sports activity when you want to freeze the action but in lower light.
Here is a play camera stimulator game. The idea of the game is to use the 3 different things including aperture, ISO and shutter speed. There were picture given and we had to add effect to them to make it correct as it was said.
