The key to obtaining ideal photographs depends on the exposure triangle of photography. The exposure triangle consists of aperture, shutter speed, and ISO. The combination of the three determines how dark or bright the resulting photo will be.
Aperture is the opening in the lens where light enters. If the opening is large, ample lighting will enter the lens. As the opening gets smaller, less light will enter. Besides being one of the ways to control incoming light, aperture is also used to control the depth of field.
In practice, if you are in an environment where the light is very bright, then the lens opening can be narrowed so as to lessen the amount of the light that enters. If the environment is a low light environment, then a larger opening is necessary for enough light to enter to obtain an optimal photograph. Read the rest of this entry » .

Photography is essentially a visual art form. Converting visualizations of what may seem to be meaningless scenes into something interesting (making something out of nothing). Interesting photographs are sometimes a result of implementing unorthodox angles, unorthodox in the sense that these angles may not be how the human eye views the world and their surroundings. […]
Photography is originated from Greek language, “photos” which literally means light and “graphein” which means drawing. In other words, it means drawing with light. Lighting is the most important part of photography and there will be times when you will need additional light sources. For example, pop-up flash (or flash featured in every camera), it […]
DSLRs (and for that matter all digital cameras) are capable of many different options and uses. Learning to use a digital camera is in some ways like learning to use a computer or cell phone or any other electronic device. The user must know which button to press or option to select, where to find […]
The 18 megapixel Canon EOS 600D (called the Digital Rebel T3i in North America) is a new DSLR camera that sits above last year’s 550D / T2i at the top of Canon’s entry-level EOS line-up. The 600D / T3i offers a 1,040,000-dot vari-angle LCD screen, a 63-zone metering sensor – identical to the one used […]
Canon today unveils the new EOS 1100D – the Digital SLR (DSLR) for consumers who want to take the first step on their journey to outstanding still images and HD video. Featuring many technologies developed for more advanced models, and functions which make it even easier to capture fantastic images straight out of the box, […]
Measuring the intensity of a flash so that it optimally illuminates its object isn’t a hard task. By using the GN formula (at ISO 100) = distance x aperture, we’ll be able to calculate the distance or aperture that’s optimal for certain conditions when photographing. But of course that formula won’t be valid when we’re […]
The use of control or button +/- on our DSLR camera is the simplest way to make an image look lighter or darker. This feature is in almost all cameras, be it digital or analog, amateur or professional cameras. What is the simple definition of exposure compensation?
