Why ‘F.Stop’

Why pick F.STOP? It’s rarely seen on digital cameras. What’s an F.STOP? It’s the numbers on a lens, f1.4, f2, f2.8, f4, f5.6, f8, f11, f16, f22, f32, f45, f64 and so on. The numbers are derived dividing the focal length of the lens by the APERTURE opening of the lens. It relates to the APERTURE of the lens, the ‘leaves’ forming the opening controlling the amount of light reaching the sensor (film). The larger the number, the smaller the OPENING or APERTURE, the smaller the number, the larger the OPENING or APERTURE.  F.STOP relates to DEPTH OF FIELD. I always strive to understand the technical part of photography so the creativity will fall into place. If a photo doesn’t come out the way I or the art director wants, I know what adjustments to make.

I’ll cover ideas, techniques, answer questions and post weekly photo sessions.
