[Finnish] Understanding Aperture, Shutter Speed, and ISO

The Exposure Triangle

  1. Aperture (f-stop): Controls depth of field (blur background) and light. Lower number (f/1.8) = more light, blurry background.
  2. Shutter Speed: Controls motion. Fast (1/1000) freezes action. Slow (1/30) blurs motion.
  3. ISO: Sensitivity to light. Higher number (3200) = brighter but more noise/grain.
