High end photography on a budget.

If I were to get a Canon Powershot S51S, do I need a dry cabinet and will it still get fungus like a DSLR?


It's better to store optical equipment like lenses, cameras in a desiccator.

The best you can do at home is to buy a air-tight container big enough to keep your camera and keep some dry silica gel crystals on one side. It's better to buy 'self-indicating' silica gel crystals which are usually deep blue in colour when dry and loose this color when they have adsorbed moisture.

These can even be heated few times to dry them again and re-used on cooling.

The silica gel pouches which are commonly found with optical equipment and even in some containers are actually a big joke and most of them are already hydrated to the extent that they can't dry a film roll container.

The best way to check a home made desiccator or a dry box is to see the colour of silica gel after 24 hours of packing everything in (including dry deep blue silica gel crystals). If the colour is slight blue but not totally white, then it's perfect.
Another method to do so is to open the box and put your hand inside. If you feel it cooler inside then it's working. It feels cooler due to dryness inside.

These are methods to store equipment for a long time. If you use your equipment regularly, there are very less chances of fungus/mold.

    As a general rule. Keep your electronic equipment in dry and not damp spaces. A camera bag with packets of silica gel will suffice. Fungus accumulation is unlikely.
