This is why you need to good cameras.
This was our last look, it was getting late, and we lost natural light in the studio. So, we had to set up a KinoFlo Diva Light for Daryon (Makeup Artist). This shot was unplanned, and actually off-set. I had the 5D rigged to a ringflash and couldn't use it... so I grabbed a RebelXT. Not a bad result, but check out the fringing (Chromatic Aberration) under the chin. Just proves... two cameras is a must.
