New and Improving - Photography!

We are no longer taking submissions but we hope this journal aides your learning!

"Photography is the art, science, and practice of creating durable images by recording light"
The first records of photography dates back centuries ago! Chinese philosopher Mo Di and Greek mathematicians Aristotle and Euclid described a pinhole camera in the 5th and 4th centuries BC. These became know as 'camera obscuras'. In the late 19th century there was a race in France to discover a way of permanently recording images. Joseph Niepce was the first to produce a lasting photographic image but Louis Daguerre invented the process that introduced photography to the masses.

In this journal we are exploring some concepts of photography!

Digital photography has only been available to consumers since about 1996 and has quickly replaced film photography in terms of popularity.

But just because taking pictures has become much easier doesn't mean you can forget about important rules when it comes to photography!

Apature

Is how much light you are letting in through the lens. Typically, a fast shutter will require a larger aperture to ensure sufficient light exposure, and a slow shutter will require a smaller aperture to avoid excessive exposure.

Shutter Speed

This is how long the lens is taking in this light. Slower shutter speeds are often selected to suggest movement in a still photograph of a moving subject. Excessively fast shutter speeds can cause a moving subject to appear unnaturally frozen.

ISO Speed
Your camera's ISO setting controls how sensitive its sensor is to the light that reaches it. It is one of the crucial factors which goes into determining a photograph's exposure as well as the overall image quality.



These Tutorials go into much more detail!

Project Educate: Aperture, Shutter and ISO SpeedToday we'll take a quick basic look at Aperture, Shutter Speed and ISO Speed.
Aperture
The aperture determines the amount of light that is allowed into the digital sensor. A small number indicates a large aperture whereas a large number indicates a lower aperture. For example, an aperture of 8 would let in less light than an aperture of 4. Imagine your eye, specifically your pupil; the bigger the pupil is, the more light is being let in and the smaller it is, the less light. This is what is effectively happening with your camera. The aperture also determines the DOF (depth of field).
The numbers you usually see on the side of lenses look like this;
F 22 | 16 | 11 | 8 | 5.6 | 2.4
The larger the number, the less light is allowed in. Each number depicts double the amount of light allowed through the lens. For example, an aperture of 5.6 will allow twice the amount of light in than 8, but only half the amount of light than 2.4.
