DIY Photography Hacks - make a foam flash diffuser: Step 6

Flash diffusers are great for ensuring more natural lighting in photos. They remove the harsh white light from direct flash by spreading out and softening light from flashguns.

However, there are dozens of models available, each offering unique features. Which is the best flash diffuser for your needs?

We tested six of the best flash diffusers available using a still-life setup, shot in front of a neutral wall using a tripod-mounted DSLR.

The rigid camera position and single light source didn’t eradicate shadows but was ideal for showing how each product diffused and/or bounced the light.

The flash was operated manually and its output was adjusted for each shot, to measure the degree of light loss each diffuser added.

A series of portraits was also shot to assess the practicality of each model, and to gauge the positives and negatives of different diffuser types.

LumiQuest’s Softbox III is up against some stiff competition in the diffusers field, considering that the well-made Lastolite EzyBox is available for a similar price (see opposite).

By comparison, the LumiQuest’s simple four-panel construction forms well, although the method of adhering it to a flashgun with Velcro doesn’t feel sturdy enough. It also means you need to have Velcro on your flash head even when you’re not using the diffuser.

But that’s not to say that the Softbox III doesn’t work. Far from it. It’s a decent enough performer for diffusing directional light, and the collapsible structure makes it portable, too.

Shadows are softened and it’s great for outdoor fill-flash work. It’s just that there are better products out there.

Our verdict
Pros… Delivers softbox-style light diffusion, and is easy to carry around.
Cons… Provides less diffused light than similar competitors, and isn’t sturdy.
