How to understand ISO in cameras

ISO controls how sensitive the camera’s sensor is to light. By increasing the sensor sensitivity you are able to shoot in darker conditions without a flash. Look for cameras that offer ISO 1600 or higher. Some cameras can shoot as high as ISO 25,000 – 102,000. Now, there is a trade-off to using a high ISO setting. Higher ISOs usually mean more noise (colored speckles) and grainier images.

• Low ISO: ISO 25,50, 100.

• Good for full sun, brighter situation.

• Medium ISO: ISO 200, 400, 800.

• Good for during the day: dull overcast sky or full open shade. Indoors: a well-lit situation or flash use.

• High ISO: ISO 1000, 1600, 3200, 6400

• Good for a darker situation, lowlight indoors or outdoors, no flash use.

• Tech notes: Help maximize the available light.

• Very High ISO: ISO 12500, 54000

• Good for hand holding the camera in very low light.

• Tech notes: use fast shutter speed to avoid blur.

It's important to use a tripod, to minimise the ISO of high ISO, to have crisper and clearer images.
