The document discusses the three components of exposure in digital photography - aperture, shutter speed, and ISO. It explains how each component affects the exposure and describes the relationship between the three. Standard settings for aperture, shutter speed, and ISO are provided, along with examples of how changing one component requires adjustment of the others to maintain proper exposure.

10. EXAMPLES: only changing the Aperture Changing the aperture only shows that if you don’t change the Shutter Speed as well, you with either Under Expose or Over Expose the image. Notice here that the small Aperture gives the most clarity. The large Aperture gives a Smaller piece of clarity. Less is in focus. Exposure: f/22 at 1/60 ISO 1600 Exposure: f/10 at 1/60 ISO 1600 Exposure: f/4 at 1/60 ISO 1600

11. Changing only the Shutter Speed shows that if you don’t change the Aperture as well, you with either Under Expose or Over Expose the image. Notice here that the Aperture is at f/7. EXAMPLES: only changing the Shutter Speed Exposure: f/8 at 1/200 ISO 1600 Exposure: f/8 at 1/100 ISO 1600 Exposure: f/8 at 1/30 ISO 1600

14. ISO 100 with a 2 second Shutter Speed ISO 1600 with a 1/8 of a second Shutter Speed Using a LOW ISO will reduce DIGITAL NOISE even in a low light situation like this. The Higher the ISO, the more Digital Noise will be visible.

15. EXAMPLES: Different Exposures, same outcome Notice that the ISO is the same in all 3 images but when the Aperture changes from a small f/stop to a large f/stop that the background becomes much softer and the DEPTH OF FIELD changes. ALL are correct Exposures. Exposure: f/22 at 1/8 ISO 1600 Exposure: f/10 at 1/50 ISO 1600 Exposure: f/4 at 1/250 ISO 1600
