What is ISO in Photography? ISO stands for  International Organization for Standardization.

In photography ISO or ASA (American Standards Association) is the sensitivity of the film (traditional photography) or image sensors (digital photography) to capture or to register images.

In Film Photography – ISO film was measured in numbers like 50, 100, 200, 400, 800 and the last value I encountered was 1600.

In Digital Photography – ISO measures the sensitivity of the image sensor. The same principles apply as in film photography.

In both digital and film photography, the reduction of exposure corresponding to use of higher sensitivities generally leads to reduced image quality (via coarser film grain or higher image noise of other types). Basically, the higher the film speed or sensitivity, the worse the photo quality.

Sample Images for Exposure using lower to higher ISO (images are shot with same aperture and shutter speed only the ISO setting was change)

Digital Photography -The New Generations of Taking Photographs

Photography is an art. It takes practice, talent, and an eye for the unexpected. Not all people will take the time to learn about landscape, wildlife, architecture, or other subject to find the secret depth within, but when they do often they will find great meaning in the photo they take. Photographers spend their time looking for new and different ways to shoot a subject. And these were the Digital Photography born. Digital photography is just one new way of taking a picture.

The darkroom is out the computer printer comes forward for most of us using digital photography. We are able to send our pictures to all our friends with a few clicks of the buttons. Digital photography makes taking a picture simple, by eliminating some of the guesswork. With the LCD screen on a digital camera you can now view the photo you just took without waiting and hour or longer to see the film develop. We are no longer limited by film capacity, but by memory cards. Most memory cards have 512MB, 1GB , 2 GB or 4GB depending on how much you’ve spent on equipment. (continue reading…)
