(Read above, Answer and submit with notes on 11-1&2) : I stands for International, S stands for Standards, and O stands for Organization The ISO people set the standards so film manufactured anywhere in the world can be similar in sensitivity if rated the same. Some cameras read the film canister's ISO from the bar code and automatically set the ISO. Film speed/ISO gets set once as you put in your film, since that is what we generally use, keep the camera set at ISO 100. Other film speeds out there are 800, 1000, 1600. We also use ISO 400 sometimes, it is more expensive, but it is better on an overcast day. We use film rated at 100 ISO, which is not very sensitive to light, which is great on a sunny day. But higher sensitivity adds grain or “noise” to the pictures. With increased sensitivity, your camera sensor can capture images in low-light environments without having to use a flash. The lower the ISO number, the less sensitive it is to the light, while a higher ISO number increases the sensitivity of your film/camera. It is the level of sensitivity of your film (or camera if digital) to available light. In very basic terms, ISO is the film speed.

Submit notes at the end of the period: Remember the lesson we learned with our Pinhole Cameras, and the aperture "glasses" (eyesight experiment) the smaller the aperture, the clearer the image, the larger the aperture, the more blur. ![]() For example, f/1.4 is larger than f/2.0 and much larger than f/8.0. Most people find this awkward, since we are used to having larger numbers represent larger values, but not in this case. A smaller f-stop means a larger aperture, while a larger f-stop means a smaller aperture. These f-numbers that are known as “f-stops” are a way of describing the size of the aperture, or how open or closed the aperture is. In photography, aperture is expressed in f-numbers (for example f/5.6). The sole purpose of the diaphragm is to block or stop all light, with the exception of the light that goes through the aperture. Large pupil size equals large aperture, while small pupil size equals small aperture.į-Stop = Size of Aperture: Large vs Small Aperture: The iris of the lens that controls the size (diameter) of the aperture is called “diaphragm” in optics. So, the easiest way to remember aperture, is by associating it with your pupil. The amount of light that enters the retina (which works just like the camera sensor), is limited to the size of the pupil – the larger the pupil, the more light enters the retina. The pupil is essentially what we refer to as aperture in photography.
