Weather not cooperating. Maybe you feel it's to gloomy out for photography but you are itching to get out and photograph something. When this happens I tend to fall back on macro or abstract images. You can find these subjects pretty much anywhere and you can shoot them in just about any light. If it's to sunny and your subject is small enough just use a small diffuser to block the unwanted light. Another bonus, you can travel light, just one camera and one lens. I would go with a normal-short telephoto focal length. Sometimes it's fun to limit yourself and see what creative images you can come up with! The image below was created with a slow shutter speed and panning the camera along the edge of a beach.
