The Ultimate Diffusion & Bounce Test with Matt Porwoll

Ultra Bounce w Diffusion 1024x503

Here at Newsshooter we review a lot of lights. Using the Sekonic C700 spectrometer, we can finitely benchmark and compare the lights against one another based on their brightness (Lux), colour accuracy and Kelvin colour temperature. We have also reviewed products which shape and modify the light including softboxes and reflector systems.

In an interview scenario, you are more than likely going to bounce or diffuse your light so you get nice soft light onto your subject so how do you know which technique to use, let alone which material to use as your diffuser or bounce source?

Award-winning cinematographer Matt Porwoll (Cartel Land, The Trade) recently decided to conduct an in-depth test comparing various diffusion and bounce materials and has compiled these results in the Ultimate Diffusion & Bounce Test.

Two C300 mkII cameras recording to REC 709 provided a familiar two camera angle interview set up.

Matt wanted to test three main methods of shaping the light. Diffusion only, bounce only and a combination of bounce & diffusion.

A handy breakdown of the different bounce and diffusion materials can also be found in the full test with a short description, approximate light loss and approximate color temperature change.

Matt tested 10 diffusion and 5 bounce materials all up.

The Results

Thankfully for Matt, he has done all of the hard work and compiled all of the results into a nice resource for all of us to use. Not only has he put together these cheat sheets but you can also watch video footage showing how the different combinations of material changes how the light wraps around the subject. Make sure you bookmark the page so you can come back to it later as Matt is also putting together a PDF of the cheat sheets.
