# A Tedious Explanation of the f/stop

by Matthew Cole Photographers set their exposure using a combination of shutter speeds and f/stops to get the correct amount of light on the sensor (or film). The shutter speed regulates how long the sensor is exposed to light coming through the lens. The f/stop regulates how much light is allowed through the lens by varying the size of the hole the light comes through. For any given film speed (ISO) and lighting combination there is one correct amount of light to properly expose the image. This amount of light can be achieved with many different combinations of f/stops and shutter speeds. Back in the days of film, that was pretty much it for exposure because your ISO (and white balance too) was set by your film choice and you couldn't vary it within the roll. Despite being one of the exposure controls in photography, the f/stop (or aperture, the terms are interchangeable) remains a source of confusion and mystery to many photographers, even to some who use it all the time. F/Stops Yes.

Photography and Math Photography and Math Copyright 2004, 2010, Mark D. Martin, All rights reserved [This article was originally a study guide written for 7th and 8th grade math students for a mini unit on photography and math. It incorporates many concepts taught in middle school math including some basic algebra, fractions, decimals, ratios, sequences, area of a circle, metric measurement, and measuring angles. Students had been taught all of these concepts before the unit. This unit helped them apply that knowledge to a real world setting.

How Recent Films Have Utilized Older or Non-Standard Aspect Ratios to Their Advantage You may be familiar with the standard aspect ratios typically found on the web or in theaters, but filmmakers have a long history of experimenting with their frames. We wrote previously about Xavier Dolan utilizing a square 1:1 aspect ratio for Mommy, but a number of other examples are explored in this terrific video from De Filmkrant: Aspect ratios have a long strange history as far as filmmaking is concerned, something that photography, another visual medium, hasn't had as much trouble with.

What Is A Fast Lens? — We Are SO Photo The speed of a lens relates to its maximum aperture. The larger the aperture (smaller the F number) at which it can operate, the faster the lens. If we refer to our article on aperture and the diagram below, we can see that the aperture of lens primarily affects the amount of light it allows in. A larger aperture (smaller F number) will allow more light in to the camera by means of widening the opening inside the lens. Observations on film art The Adventures of Prince Achmed. Kristin (with some help from David) here: David and I have been offering this greatest-of-90-years-ago series almost as long as this blog has existed. For earlier annual entries, see 1917, 1918, 1919, 1920, 1921, 1922, 1923, 1924, and 1925. I approached 1926 with the assumption that it would present a crowded field of masterpieces; surely it would be difficult to choose ten best films.

Photography Aperture & Aperture Priority Mode nobadfoto.com Aperture is the hole inside your camera lens. This hole, known as the diaphram is formed by a number of overlapping blades that adjust to control the size of the hole opening. Depending on the type of lens, the hole opening or what we will refer to as aperture can be adjusted manually on the lens (Manual Lenses) or automatically (Automatic Lenses) by your camera using buttons or dials (on the camera). When you do this adjustment, the aperture either increases or decreases which in turn controls how much light can pass through the lens and onto the digital sensor or film. Aperture settings are expresssed in f-stops and are represented by numbers (i.e. f/2, f/5.6, f/11, etc). El arte cinematográfico - Bordwell y Thompson You're reading a free preview.

8 Tips for Safety and Etiquette When Photographing at Night A couple of recent incidents involving careless shutterbugs light painting with burning steel wool have gained a lot of notoriety in the press, giving legitimate night photographers a bad reputation. With these unfortunate matters in mind, we interviewed a variety of night-photography specialists to compile the following eight tips on safety and etiquette when photographing in the darkness. Lead Image © Troy Paiva 1. Digital Photography An introduction to the scientific, artistic, and computing aspects of digital photography. Topics include lenses and optics, light and sensors, optical effects in nature, perspective and depth of field, sampling and noise, the camera as a computing platform, image processing and editing, and computational photography. We will also survey the history of photography, look at the work of famous photographers, and talk about composing strong photographs. This course is based on CS 178 (Digital Photography), which I taught at Stanford from 2009 through 2014.
