5 reasons to use a soft box with LED lighting

LEDs are a highly efficient light source, and putting aside any color spectrum issues, (that have generally been improving) they still have limitations for lighting people. The naked illumination coming off a single emitter, or an array making up a larger fixture, such as a panel, is just not the soft, beautiful glow that we seek for human subjects.

Some softening of the light is called for, but adding diffusion can decrease output and make the source harder to control. In fact, earlier generations of LED fixtures lacked the lumen output to afford much diffusion. However, technological advances in LED electronics, and the design of certain light modifiers known as Soft Boxes now make them an essential combination.

Here are five reasons I like to use soft boxes, especially when taking advantage of an LED light source:

1) A large source is perceived as the most natural looking light, and a Soft Box generally expands the surface area of the source.

2) The separation between the diffusion material and the source created by the Soft Boxes lessens the light loss by filling a larger surface area with light and also by not wasting stray light. Instead, this otherwise unused light is amplified via the silver reflective lining that makes up the inner walls of the Soft Box.

3) At the same time, the Soft Box helps control spill and with the addition of grids, which attach easily to the outside of the diffusion, the light can be channeled to work where it should, and be eliminated from areas where it shouldnt.

4) Attaching a Soft Box directly to the fixture reduces clutter on the set by avoiding extra stands that might otherwise be required to hold diffusion frames and various cutters thus speeding set up and breakdown.

5) If a white rectangular reflection is picked up in the background, it can more easily be taken for a natural source, like a window, as opposed to seeing the bald spectral points of LEDs flashing camera.

Keeping Your Post Prodction on Track with Subclips and Search Bins
Alex Macleod

For my 2nd Kit Plus article I thought I’d try and build on the theme of my first, and that’s one of making sure things are organised at all levels of your post production projects.

Last time I talked about trying as best as you can to stick to the ‘two week rule’, making sure that the names & locations of every asset you import, and every bin & sequence that you create in your project - will make sense to you regardless of how long it is you spend away from it.
