When I was in Key West recently, I had lots of fun playing around with intentional camera motion (ICM). Walking around Duval St., I simply centered myself, enjoyed strolling with my husband, and tried to open to the erratic energy and flow of Key West at night. Lots of people and bicycles and bright lights. It is very easy to create intentional camera motion images at night, and easy to create interesting compositions when there are lots of lights and people. Some of my inspiration comes from the night ICM street photography images of the noted photographers, Ernst Haas and Harry Callahan. By moving your camera as you press the shutter button, you are literally painting with light.
To create ICM images simply be sure your shutter speed is set to around 1/10. It helps to play around in each environmental setting where you find yourself and see what camera setting works best for the environmental setting. It's easy to get the camera settings right for slow shutter speed ICM at night. During the day it's more challenging because the light is so bright. With bright daylight, you can accomplish selecting a slow shutter speed by setting the aperture to f 22 or higher. And if that is not enough, then add a neutral density filter (I often use .9 in the bright FL light) to your lens, and you are good to go. If you have never used a neutral density filter, it's worth giving them a try. They are relatively inexpensive, and are also very useful for creating slow shutter speed images, on a tripod, creating those silky water effects, etc. With iPhones, you can download various slow shutter speed apps and create ICM images even with your phone.
