Cameras for Greek island travel

Two cameras cover a Greek island trip properly, and they divide the work cleanly: one for stills on land, one that goes in the sea. Trying to make a single body do both is where most kits go wrong, because the thing that makes a stills camera good — a large sensor behind a piece of glass you do not want salt water near — is exactly what keeps it out of the water.

For the water half, the specification that matters is bare waterproofing rather than a housing. An action camera rated to twenty meters without a case can go snorkeling off a sheltered bay, off a boat and into the shallows without a decision being made first, and a camera that requires a case is one that stays in the bag when the moment is short. Read the manufacturer's own spec rather than the category: some very good small cameras marketed for travel vlogging are explicitly not dustproof, waterproof or splashproof, which makes them the wrong tool for an island whatever else they do well.

The most useful thing to know about action-camera video has nothing to do with resolution. Shoot at normal speed — four-K at thirty or sixty frames — and slow footage down afterwards if you want it slow. Dedicated slow-motion modes at a hundred and twenty or two hundred and forty frames produce files that play back already-slowed on Apple devices and can be rewritten to a lower frame rate on export, so you lose the ability to decide later and sometimes lose the effect entirely. Leave stabilization on, switch to the horizon-locking mode on boats, and record in H.265 unless you are editing on an older machine that will struggle with it.

On the stills side, the useful discipline is to bring two small lenses rather than one versatile big one. A moderate wide for streets, architecture and people-with-their-setting, and something near a normal focal length that opens wider for portraits and low light, will cover a trip between them. Ultra-wide zooms are the ones to leave behind: they are heavy, they usually force a second body, and the bulbous front elements on the fastest of them cannot take a screw-in filter at all — which costs you the one filter that genuinely matters here.

That filter is a polarizer. Greek light is hard, the sea is reflective and the sky is the thing everyone photographs, and a circular polarizer is the only filter that does something you cannot reproduce afterwards: it cuts the glare off the water so you can see into it, and deepens sky without touching anything else. Rotate it to taste and stop before the sky goes unnaturally dark.

Take it off as the light drops, though, and this is the mistake worth naming. At golden hour, with the family at dinner, both a polarizer and a variable neutral-density filter are stealing light you need for a shutter speed fast enough to keep faces sharp, and the polarizer mutes exactly the warm glow you stayed out for. Clear filter or bare lens, open the aperture, put the low sun behind them, expose for the faces and raise the ISO without guilt.

Two small things that matter more than they should. Group portraits on a large sensor need stopping down to something like f/4 to f/8, because wide open only one plane is sharp and somebody will be in front of somebody. And a silica gel pack in the bag earns its place — island air is humid and salty, and it is working on your gear the whole time you are not thinking about it.
