I realized that my growing understanding of photography can be captured in a series of facts and guidelines:
- Hold the camera as still as you can.
- Take lots of photos.
- Throw away photos you don't like.
- Get closer to your subject.
- The subject doesn't have to be in the center of the frame.
- The slower the shutter, the blurrier the image will be.
- The lower the aperture number, the wider the actual aperture (the opening in the lens that lets in the light).
- The wider the aperture, the more light gets in, so the faster your shutter can be to get the same exposure.
- The wider the aperture, the shallower the depth-of-field, so the background will be blurry.
- A lens with a wider maximum aperture is called "faster" because it lets you use a faster shutter.
- The higher the ISO number, the more sensitive the sensor, but the more noise in the image.
- A lens will be sharpest in the middle of its aperture range.
- Back-lit subjects are really hard, but different metering modes can help.
- Shooting in RAW gives you more flexibility in post-processing, but gives you the largest files.
- Filters do magical things that I don't understand yet.
I'm not sure I can encapsulate my understanding of other fields aphoristically like this. It would be interesting to try.
