DIY Camera Dry Box

DIY Camera Dry Box

I usually store my camera gear in camera bags. I store my primary shooter in a sling bag. I would also cram extra lenses, flash and whatever other gear that can fit into that same bag. All remaining gear would go into miscellaneous camera bags.

I had to rethink this when I was searching for used lenses to put on my Canon EOS M (my primary video shooter). It’s a given to check the quality of the used lens. Does it have scratches? oily blades? fungus? Fungus… huh? After some searching, fungus primarily grows on the lens. Given the right conditions, it can spread. Can it be cleaned? By a professional. So what do you do? Prevention is the key. The fungus spores thrive in damp environment. I live in the Bay Area, but that’s no guarantee that fungus cannot contaminate my lenses. Keep in mind I’m still buying used lenses… dunno where they’ve been.

One form of prevention requires storing the lenses and camera body in a cool and dry environment, the camera dry box. Professional camera dry boxes are way too expensive — from a couple of hundred dollars to well over a thousand. One solution to make your own camera dry box. That requires a storage container, a desiccant (to absorb the moisture within the container), and a hygrometer (to measure the relative humidity).

Here’s a video of my DIY camera dry box:

Here’s a price breakdown of my diy camera dry box:

  • 10.5 oz DampRid: ~$3 @ Home Depot
  • HTC-1 Digital Thermometer and Hygrometer: ~$5 @ eBay

    I made a diy dry box but use silica gel instead of damprid. Silica gel is reusable but you need an oven or microwave to heat the silica gel beads.

    I find it is easier to control humidity with silica gel by putting extras in a bottle and opening the bottle when humidity in the dry box starts to rise.
