how to DIY a hands-free light reflector for perfect photography


In Seattle, homes are not designed to be air-conditioner friendly. It was during one particularly hot streak last summer that I went to a big box home improvement store for some insulation to place around my apartment’s portable air conditioner vent and discovered along the way the best (and cheapest) photography light reflector I have purchased in years! Read on to learn how to source the material to make your own hands-free, free-standing light reflector for amateur studio photography.

What is a Light Reflector?

Photography light reflectors help direct or diffuse light, producing a more evenly lit photo when adjusted just right. Typically deflectors are umbrella shaped or are pop-up-style awkward frames with metallic fabric stretched across them. For me, neither style has worked well for use when shooting solo. Using these reflectors well usually means having to have an assistant on hand to hold and tilt the reflector just right.

I never guessed that the roll of metallic insulation I found for my air conditioner unit would become my most reliable and essential piece of photography equipment in my product photography and Instagram flat lay photography side business!

Material for DIY Light Reflector

My photo reflector is made from double layer bubble insulation. It’s literally just two layers of bubble wrap fused together  – in theory, to create better insulation – but the dual layers actually work great to give the material structure and the ability to stand on its own and curve slightly. The bubbles are lined on both sides with a bright metallic surface that was designed to reflect light. The product designers intended to reflect the heat-energy produced by direct light, but inadvertently created a really good diffused reflector for studio photography.

There are several brands of this type of insulation, but this brand in particular I can say has the appropriate reflective levels and rigidity

A Cheap DIY Alternative for a Photo Reflector

I did the math, and it turns out the photography reflector I most recently purchased, through a discount seller on eBay, still rang up at a cost of 1.38 per square foot of reflective material. In contrast, the insulation reflector (which doesn’t need an assistant or a stand to hold in place) rings up at only 69¢ per square foot of reflective material.

When to use

I’ve only used my reflector for indoor studio photography, as a way to even out and diffuse natural sunlight in my bathroom-turned-photo-studio that gets great light from its Puget Sound view. I haven’t tested it, but I think that it would work well for outdoor photography as well, and since it can be rolled and bundled without being damaged, would be a great choice for travel photographers or for opportunistic photographers who like to keep equipment stowed in their vehicle.

My “Studio”

Here’s a photograph of my little makeshift studio in my apartment. I kept in uncropped so you can see it’s literally just set up next to the towel rack in my bathroom. I keep a sheer curtain on the window to diffuse incoming light  and place my DIY photo reflector in a curve on the opposing side of the window. This helps bounce back the light and even up my shadows.

In this photo I’m simply using a thin role of basic white paper as a backdrop – making it easy to  edit out later.

After a bit of editing, here’s an example of a photograph I took using this photography hack. With only one window of natural light and a 4′ x 4′ sheet of insulation used as a photo reflector I was able to create these professional shots without extensive equipment or photo editing.
