U.S. Use gestures. Motion across the photo is harder to stop than motion toward the camera. The image moves more relative to the film. This rarely produces useable photos, however. Objects like telegraph poles and fences often get in the way at the moment you shoot.
Careful composition is virtually impossible.
Window dirt hazes up photos. You can hold the camera more steady if you brace it against something solid. Use a chair back, a door frame, your elbows on a table top, your knees to brace the camera. If you catch a pause or a peak in a gesture you can often get a non-moving shot at a slower shutter speed than if you shoot randomly. If you are not sure of an exposure, or if it is tricky, bracket your exposures.
