I have a love/hate relationship with continuous lighting. On one hand, I see the absolute necessity in bringing it along for every single shoot, especially since I tend to use smaller-sensor cameras that aren't necessarily the best low-light performers. Enter the Scorpion Lights. (That totally sounds like a kung fu movie)
As a video editor, occasional graphic artist, and hoarder of all manner of digital files I feel like I can never have enough space and, more importantly, enough disk performance. The faster your disk array, the more concurrent video streams you can play, the smoother playback of high resolution or high framerate videos will be, etc. It's with all this in mind that I can confidently declare the ExaSAN A08S3-PS one of the best RAID arrays I've ever used, but at a cost.
Speaking as a DSLR/Blackmagic Pocket shooter, I have a lot of SD cards of various speeds and sizes lying around. I thought removing them from the equation and switching to (surprising similarly priced) SSD drives would be a challenge, but it's actually proved far easier than I imagined with the Atomos Ninja Blade.
If I'm not mistaken, the Promise Pegasus R4 and R6 were the first commercially available Thunderbolt drives and show stealers at NAB 2011. That doesn't come as much of a shock when you consider that most editors were still using bus technologies that were nearing a decade old at the time. Thunderbolt made some hefty claims about speed and expandability and has followed through on them nicely if not a bit slower than expected.
One of the worst situations to be in while on a video shoot is not having enough light. Your footage will either turn out noisy because of a high ISO or worse: underexposed. I recently took a Litepanels MicroPro out on shoot with me because I wasn't sure what kind of lighting conditions I'd be dealing with and boy am I glad I did.
