Assorted notes from me trying to teach myself Photography.

The Triangle

It’s a balance between Aperture, Shutter Speed, and ISO.

Metering

Your camera will try and advise you. People used to use light meters for this. It will say its a good exposure if it is “18% Gray” which is what light meters were historically calibrated to (the caps on Kodak film and the insides of dedicated camera bags are this gray too.)

The Histogram

On Aperture

Measured by f-stop. “f/2” means you take the focal length and divide it by two.

“f/8 and Be There..” Like be there. Your camera primarily exists to take pictures of things and events.

On ISO

See this video. TLDR: This is tricky so let the camera figure it out.

Tripods

  • Cheap, Stable, Light —- pick two. But don’t be cheap. You’ll change cameras before tripods.
  • Read this thoroughly.
  • Components are: Legs, Head, Plate, Bag
    • Each component may be purchased separately.
    • Buying a head doesn’t necessarily include a plate.

Presets and LUTs

For Photomator/Pixelmator

Lenses

There are Prime lenses (fixed focal length) and Zoom lenses (can be wide, normal, and/or telephoto lenses).

Prime lenses teach you a lot about photography because they make your lazy ass move and explore a scene: distances and angles.
