ISO Explained - how to use it

Now we're going to explain how to use ISO to get the shutter speed you want or need whilst shooting some real photos. In the first explanation I'm using a wide lens with a small aperture for max depth of field. But on a dull day my shutter speed gets very slow and I'm in danger of getting a blurred image through camera shake. To get a faster speed the only way I could do it was to boost the ISO so the camera becomes more sensitive. This isn't a problem very often when shooting wide - but remember it's your ISO that'll get you out of trouble. With a longer lens using ISO becomes much more important because long lenses suffer from camera shake - especially on windy days!
