My cousin Sheldon and I played a game called quick draw.
The idea was when we met up, the first to take the others picture was the winner, prizes to be determined later. This exercise had many learning experiences.
You learn the art of the grab shot. Whenever I go out with camera I'm ready to shoot. Many spontaneous images are fleeting and offer no repeat chances. Having the camera focused and exposure determined is a huge advantage that even our automatic cameras may fail you on this. Better to know how to override the system and always be prepared. Using the same film (yes, I said film) or ISO will get you used to what is necessary for that image. Keeping your eyes open to possibilities helps keep you fresh and ready for whatever comes. I have posted three example of this game in my gallery with pictures I took or Sheldon did of me.
Another game I played was called saturation. The idea was you would take a large number of different images in a small contained space, whether it is a building, an office, or a region. If you limit where you can go, you must expand your vision to see different views, while others see only the same old. As a side advantage, you lose all fear of intruding on others and I have found as you get closer, the image has more impact. This is where the wider lens has the advantage with more depth of focus, not the narrower telephoto, which offers the photographer the comfort of distance, but also may minimize the impact in the final image. For those familiar with my portrait style you can see this influence and decide if this has an advantage. I have posted two folder examples, Klotter Street and Sycamore Street Hill, in my gallery.
I also play, may I get involved in your life? As you get closer to strangers, you had better be friendly.
There is no way to hide from only a few feet away. This means you must meet the subject or at least let them know you are there with them. A word, or smile is usually enough and it offers a perfect opportunity to find a way to give them a copy, and a chance to get approval to post the image. There are many examples but if you check out my street documentary images, you will the idea quickly.
If you have any more ideas or suggestions, let me know. I am always up for a new or novel tip.
