ISO is the film speed. Film speed refers to how fast or slow the camera reacts to the light given. In other words, how sensitive the film or pixels in the camera are to light. Back in the day, when we bought film, we would choose the film speed for the whole roll. We would buy ISO 100, 200 or 400 speed film. Now days with digital cameras we can change the ISO with every picture if we desire.
As a class we experimented with ISO. We started off by taking a picture of our partner in a dark room, lit up with Christmas lights, with the flash on. We then turned the flash off, and with our camera on P mode (Program mode:The camera chooses the appropriate aperture and shutter speed) we took pictures at different intervals up the ISO scale.
