Silica Gel absorbs moisture in the air around your camera equipment (such a material is called an adsorbent). This ensures that the area is not friendly for fungus to grow inside your camera lenses (article I wrote about keeping fungus at bay). But did you know that if you leave silica gel inside your camera bag for too long it can get saturated with moisture and actually start to give off some of that moisture later on? This could really mess up your equipment. I didn’t know this myself, until a few years ago.
Here’s how you can avoid this potentially huge problem, and recharge / reuse Silica Gel sachets or crystals that you use to keep your camera equipment safe from moisture.
