The Pros and Cons of ISO
By Ione Ascanio Green & Ian Wedgewood posted 08/02/08
ISO is the scale used to measure the light sensitivity of your camera, and it can be tricky to get it right.
The scale usually starts at 100 (some cameras start at 50) and can go to 3200 and beyond. At 100 your camera is ultra clear and but is the least light sensitive. This means ISO 100 is perfect for a bright day and is produces crisp pictures.
Once lack of light becomes an issue it's time to turn up the ISO to compensate. So an overcast day may need ISO 200 and indoors you'll most likely need ISO 400.
The higher the ISO the more 'noisy' the images become. Noisy images are pictures where you can see abnormal coloured pixels in the final image, they make the image look grainy, you can see lots of examples when you use a camera in low light and don't use the flash. As always, experiment! This can sometimes work in your favour to create a different style and atmosphere.
