Tutorial: How to Design a Greenscreen Environment for Office Shoots

照明 the Greenscreen

最优, you light thegreen screen separately from the subject, and I have a set of cheap compact fluorescent softboxes for that chore. 具体地说, I bought the fancier Studio 3000 Watt 照明 Kit With 3 Stands and 3 softbox 照明 Kit for about $160, primarily because it came with three lights, one with a boom to serve as a hair light. The two lights were perfect for lighting the greenscreen, but the hair light was too unfocused and created highlights on my forehead, so I didn't use it. A good backlight really needs a focusable element, 是否一个镜头, barn door or egg crate, to avoid that problem. Still, for $160, I marvelled at how cheap and effective lighting has become.

I positioned both lights about head level on the background, trying to produce even lighting on the portion of the screen that showed behind me in the shot. In the small setup shown in 图3(下面), these four-bulb lights worked perfectly.

You need separate lights for the subject, and for this I used some ePhoto当然 that I've had for awhile, 具体地说, the ePhoto VL9026s 2000 Watt 照明 Studio Portrait Kit, which now costs $167 on Amazon (下面的图4) . I’ve had these for just under two years, and they provide lots of cheap, 无向光, which is perfect for office shoots like this one. You don’t have the control for moody, 微妙的照明, but for flat or slightly shadowed lighting, 他们的理想. Both sets of lights are daylight balanced, so I didn't have to put shades on my windows.

If you look at Figure 1, you can see that I've positioned these lights slightly above my head pointing towards my face, both about 45 degrees from my nose, with one light using 3 bulbs, the other 5 to create a slightly shadowed look to model the face. You can see that in the final video below.
