Aperture aka: “f/stop”

₩ Welcome, and thank you for visiting. The following images were created to demonstrate and explain the term “f/stop” (aperture) in this series.

₩ Some beginners are not familiar with this term, what it represents and how the results “look.”

«» F/STOP Explained:

In optics, the f-number (sometimes called focal ratio, f-ratio, f-stop, or relative aperture[1]) of an optical system is the ratio of the lens’ focal length to the diameter of the entrance pupil.[2] It is a dimensionless number that is a quantitative measure of lens speed, and an important concept in photography.

• The image shown, was created using the following:
^ Canon 70D
^ Metz 58-A2 flash in E-TTL Mode
^ Canon 70-200 mm L Series IS II

• Note the lighting variables with the change if the f/stop (range I used) from f/2.8 to f/5.0.

• Compare the colors and textures of the image.

• Practice with items or people in your “space.”

• Experiment with f/stop and ISO variables to achieve similar and various optical results.

* Happy shooting 🙂
