We are all creatures of habit. We go out for a day of photography and we tend to make the kind of pictures day in and day out. Perhaps it is people on the street or beautiful landscapes or buildings and cities. We might have our own style to them, but we use the same aperture and shutter speed. We stand with our cameras up to our eye and press the shutter.
Try going out and if you are right eyed use your left eye when making pictures for the day. If you always make pictures straight on including the whole person, try making a picture of a person from behind, or just their hands, or even feet. Experiment with different modes. Spend a whole day just focusing on one small part of a person, or building. Make photographs of just door knobs or staircases. If you have never photographed animals try to make as many pictures of animals as possible, maybe sitting in the middle of a park on the grass, from the level of the dog's perspective.
A few months ago I was overseas and I went to a park. I sat down in the middle of the playground with my camera placed on my tripod. After about 5 minutes I noticed that people stopped paying attention to me. This gave me a good opportunity to make pictures of children being children. They were playing tag or chasing each other laughing and smiling. Being down low gave me a wonderful opportunity to get up closer and capture their expressions which would have been lost if I was standing.
Take your camera out on a rainy day and make photos of raindrops, or puddles. The reflections off a window can be very lovely. Yes, of course protect it with plastic wrapped around it just exposing the lens. I also take an umbrella stick it in the back of my jacket (yes, I do look a little strange, but most photographers look strange anyway) I then take a large plastic baggie and wrap it around the body of the camera and cover everything except the lens. Secure it with a rubber band or tape. Of course you can buy professional wraps, but I find that this works out well for me, because sometimes I want to use a different camera or lens. But I caution you make sure that your camera is really protected especially if it is a digital camera which is much more delicate that a film camera.
You will be surprised at your work. I hope this will give you some ideas for a pleasant day of picture making.
