I’m Ruhani Rabin, a Social Media Researcher who also have a passion for photography. I’m a newbie photographer. I do not have enough time to explore and shoot. But I do like to take photos which can live through time.
F22.in is my photography showcase along with Inspiring photos from talented photographers around the world.
Each of the photos tied up with a music to compliment the emotional state of moment! This is my own concept.
What is f22?
F22 is one of the F-number settings known to SLR cameras.
In optics, the f-number (sometimes called focal ratio, f-ratio, or relative aperture) of an optical system expresses the diameter of the entrance pupil in terms of the focal length of the lens; in simpler terms, the f-number is the focal length divided by the “effective” aperture diameter. It is a dimensionless number that is a quantitative measure of lens speed, an important concept in photography.
