Spot the difference: flashlight edition
Top: two slow lorises under red light. Bottom: a slow loris under white light. Under red light, they are relaxed and behaving normally. Under white light, it is frozen in fear, squinting in the blinding light, unable to run away.
Many forest guides ban flash photography and think that covers it — but a white torch beam or filming light held on an animal causes the same reaction, often for longer than a single flash would. Banning flash means nothing if white light is still being used to walk or film.
If you’re ever planning a night walk, ask your guide one question before you go: red light for the whole encounter, walking and filming both — not just no flash. If they can’t say yes to that, that’s your answer on whether to book them.
