The most powerful photographs are often the ones where the subject doesn't know they're being photographed. Achieving true candid work isn't about being sneaky — it's about building an environment where people forget the camera exists.
I've photographed everything from street scenes in Mumbai to private family moments at weddings. In each case, the approach is the same: spend time before you shoot. Let people get used to your presence. Have your camera out, not raised, for the first hour.
1. The equipment question
A smaller, quieter camera is your friend. I switched from a DSLR to mirrorless largely for the silence of the electronic shutter. The sound of a mechanical shutter is a constant reminder to your subjects that a photograph is being taken.
“The best candid shot you'll ever take is the one where nobody — including yourself — was fully prepared for it.”
2. Timing and anticipation
The decisive moment is real, but it's also often preceded by many almost-moments. Watch for tell-tale signs: a head about to turn, a hand rising to gesture, eyes that are about to meet. Pre-focus on a spot and wait for the action to arrive there.
