  • Condensation forms quickly on lenses; let gear acclimate and carry a cloth.
  • Tell someone where you're going in remote areas and carry the ten essentials.

Season: Winter gives the most dramatic steam; some primitive springs are only accessible in summer.

Suggested gear: Circular polarizer, Lens cloth, Telephoto for distant pools. Work out exposures with the depth of field, ND filter and NPF rule calculators.
