ISO Settings in Digital Photography

Image
What is ISO? In traditional (film) photography ISO (or ASA) was the indication of how sensitive a film was to light. It was measured in numbers (you’ve probably seen them on films – 100, 200, 400, 800 etc). The lower the number the lower the sensitivity of the film and the finer the grain in the shots you’re taking. In Digital Photography ISO measures the sensitivity of the image sensor. The same principles apply as in film photography – the lower the number the less sensitive your camera is to light and the finer the grain. Higher ISO settings are generally used in darker situations to get faster shutter speeds (for example an indoor sports event when you want to freeze the action in lower light) – however the cost is noisier shots The difference Notice the increase in graininess for 3200 ISO shot 100 ISO is generally accepted as ‘normal’ and will give you lovely crisp shots (little noise/grain). Most people tend to keep their digital cameras in ‘Auto Mode’ wher...

Photography Basics

Let's start with a few photography basics. We'll be talking about the exposure triangle. This would help us give a better understanding of the below mentioned features. ISO– the measure of a digital camera sensor’s sensitivity to light Aperture– the size of the opening in the lens when a picture is taken Shutter Speed– the amount of time that the shutter is open In order to get the correct exposure, we need to master these three elements. Most importantly – a change in one of the elements will impact the others. This means that you can never really isolate just one of the elements alone but always need to have the others in the back of your mind. There are numerous examples to simplify the relationship between these three, let me take the simplest approach to give you a better understanding. The Door Imagine your camera is like a door with shutters that open and close. Aperture is the size of the door. If it’s bigger more light gets through and the...
