I was curious why daylight and tungsten was easier to deal with, especially for skin tones. Looking at the spectral distribution of light, tungsten and real daylight provide a continuous spectrum of light, while fluorescent/CFL produce highly spiked light- not continuous. The good news is that the latest LED lights come very close to tungsten/daylight for continuous spectral light. I've got some low-cost CFLs in 2x3 and 2x2 light rigs: I'm going to replace the CFLs with LED bulbs at around 5000K (probably Cree- thanks for the tip FilmMan!) to match the other ~5000K LED lights I use (currently Z96, YN300, YN600, and F&V R-300). An LED spot in a clamp-on work light will also be handy. http://www.cs.cmu.edu/~zhuxj/astro/html/spectrometer.html http://www.popularmechanics.com/technology/gadgets/tests/incandescent-vs-compact-fluorescent-vs-led-ultimate-light-bulb-test#slide-1 (see the spectral charts) (CFL can work OK, but I had to use a tuned camera color profile and make sure WB was set carefully, otherwise trying to fix in post was time consuming).
Cheap CFL bulbs are convenient, efficient and economical - but they typically have a lower Colour rendering index compared to Tungsten based lights and other more expensive lighting systems. Just how much of a difference is there? You decide (additional images/stills on my website: http://www.tommajerski.com/critest.html ) Shot on the BMCC 2.5k in Raw mode.
