Field-craft tips#
- Terns dive — use 1/3200 s and continuous tracking AF.
- Bright sand and surf fool meters — dial in exposure manually or with auto-ISO and compensation.
Ethics#
- The welfare of the animal comes first: if it changes its behaviour because of you, you are too close.
- Stay on trails, respect closures around nests, leks, dens and haul-outs.
- Avoid playback and baiting in sensitive seasons; never bait predators.
- Don't share precise locations of rare, nesting or roosting animals publicly.
