- Stops and Pupils: 5.1 Introduction . One of the most important concepts in optical design is that of the stop and its associated pupils. Most of us have used a stop (whether we knew it or not) when taking photographic pictures. * Most good quality camera lenses have an internal adjustable iris by which one can control the exposure.

- The entrance pupil (EP) is the image of the stop into object space, and the exit pupil (XP) is the image of the stop into image space. The pupils define the cones of light entering and exiting the optical system from any object point. There is a stop or pupil in each optical space. The EP is in the system object space, and the XP is in the system image space. Intermediate pupils are …

- If you were to increase by 1 stop from f/5.6, the correct aperture would be f/4. The math is 5.6 / 1.41 = 4. A decrease from f/2 to f/2.8 is one-stop since; 2 * 1.41. = 2.8. For those that don’t like math: a visual tool like an exposure triangle will illustrate the increasing and decreasing of light based on the aperture options. And even the shutter speed + ISO settings are included too.

- F/1.8 + 1 stop = F/2.4. F/5.6 – 1 stop = F/4. Remembering this scale of stops in aperture can make it much easier to make full stop adjustments. There are also additional F-stop settings outside of this range, such as F/6.3 or F/13, to make a note of. By using one of these settings, you are adjusting your exposure by partial stops. There’s no problem with this, but …

- The simplest way to change your aperture by a stop is just to move the aperture dial on your camera three clicks. The third exposure factor, ISO, is also measured in stops. Like shutter speed, the relationship between the values is simple. To increase your ISO by a stop, double the value, say from ISO 100 to ISO 200.
