Here are some ways to train yourself to see with camera vision.
In my classes, I photograph a side-lighted soda can.
My students can then compare what they see with their eyes, with the photography vision of the soda can on a monitor.
You can do the same with the previous Play with Light exercises.
Find a scene that has brightly illuminated areas, and areas with dark shadows.
Using the shutter-priority exposure mode (S or Tv), set your shutter to about 1/500th of a second.
Point your camera at different parts of the scene, and write down the f/stop that your camera's light meter selects.
You might end up with a range of apertures like this one.
Generally, if you have a more than a two-stop difference between the bright and dark areas, you may be disappointed in the resulting photograph.
When you encounter a scene with too much contrast, use the techniques on the following pages.
Be sure to place examples of camera vision into your visual notes folder.
