Aperture f/1.8, Shutter Speed 1/2000th of a second, ISO 200Aperture f/8, Shutter Speed 1/100th of a second, ISO 200 Aperture f/16, Shutter Speed 1/25th of a second, ISO 200 Aperture Priority gives the photographer the ability to adjust the depth of field in many new camera types that we have today. While taking these photos we discovered that aperture is expressed in F-numbers and the lower the number the wider the aperture. The opposite occurs when higher F-numbers are used to shrink the aperture. With this experiment we used three different aperture settings including, f-1.8, f-8, and f-16. The visual difference between the higher and lower aperture settings include an obvious depth of field change. With an F-number of 1.8, only the first box is in focus and the background is blurred. As the F-numbers get higher it improves the depth of field and begins to show more of the background. Once the F-number is at 16, you can clearly see that all three boxes are in focus.
