Day 4 of Better Photos Series

Day 4 is about ISO, the measurement of how sensitive the camera is to light.

ISO= 100 shutter speed 1/0"6

ISO= 200 shutter speed 1/0"3
both shot in P creative zone

What I learned: the higher the ISO, the shorter the shutter speed
the lower the ISO, the longer the shutter speed and the harder to hold the
camera still that long, therefore-I need a tripod!
