Thanks useful information: 
What better way to start 2011 with a new series of challenges for the AP members learning how to use their cameras. So if you are New To Photography, give these challenges a go, learn to get off Auto Mode, and understand how camera features work, and interact with each other.
This challenge to our members that want to learn to take control of their digital camera is based on the Learning Centre topic : ISO.
ISO adjustment increases the 'sensitivit'y of your camera's sensor. This is done electrically and the more 'sensitive' you make your sensor to light, the faster shutter speeds you can achieve.
So we would like you to set your camera to Aperture mode, and set it to the smallest aperture you can. Usually f22 (remember the larger the number the smaller the actual aperture). Now make sure your camera is in manual ISO mode (refer to your camera manual in need).
THE CHALLENGE: We want you to go out and take two photos of the same subject. One at ISO 100 (some may have to use 200 as it could be the lowest number available to you). Then using the same subject, change the ISO to 3200 and take another photo. If your camera allows very high ISO try one at ISO 8000 or above as well. Present your photos in this thread and tell us what you have learnt from increasing the ISO.
Specifically, what happens to your shutter speed and what happens to the quality of the photo produced? Tell us what you observed.
The full New To Photography Learning Centre is in the Ausphotography Library, under New To Photography
Looking forward to seeing your two/three photos presented for the challenge and your discussions about what you have learnt from the challenge, and how changing the ISO setting can visually affect the resultant photos. Also remember to look at what changing the ISO does to the other camera settings. What happens to the shutter speed, and why does it happen
