For this challenge turn your cameras mode dial to program mode (P). The camera will pick the shutter speed and aperture for you, you will just be adjusting the ISO. Try taking pictures in different ISOs. Remember no flash!
I used Lolli and Beth’s suggestions and did a toy photo shoot
I took these photos with my Sony Cybershot DSC-H20

Fun Fact : ISO stands for "International Organization for Standardization" and is taken from the Greek word "isos", meaning equal. See www.iso.org. ISO has replaced the older ASA designation.
