The guys over at SLRLounge came up with a video tutorial about that shows how to create a video light configuration for an intimate interview.
I spoke on the merits of worklights before as a very inexpensive option for shooting stills, but this video shows how they also work great for video. Pye Jirsa does mixes several light temperatures in a very Strobist CTO Overdrive way to gain cool light effect on one side of the interviewers face. Sweet.
I tried to tally up the actual numbers and came up with something close to $60, not bad for a video setup considering that even the most basic dedicated video lights cost around $40-70.
