Building a tabletop shooting studio

Now that we’ve established the potential pitfalls of fluorescent lighting, it was now my ambition to see if I could build an off-the-shelf lighting system using parts from Home Depot.  In some ways I was successful, and in others I faced some intersting limitations.

Knowing that the end goal is shooting some of the food we cook for my wife’s site The Fashionable Foodie, I decided that I would set a few parameters before shopping.  Since we’re both new at this, I wanted to minimize as many variables as possible.  We have very little experience plating, styling, photographing, lighting and setting scenery, so I thought it would be best to cut out table settings entirely.  I decided to begin by building a table-top cyclorama to shoot all the subjects on a plain white background for simplicity’s sake.

Correlated Color Temperature and Color Rendering Index

In my last post, I stumbled through an explanation of what Color Temperature is and why it doesn’t apply to fluorescent lighting.  But, if Color Temperature doesn’t apply to fluorescents, why do they put a color temperature measurement on most florescent light packaging?

Well, they’re not deliberately trying to be deceitful, what they’re using is a Correlated Color Temperature or CCT.

Effectively, the rating listed on the packaging of a given bulb indicates the incandescent color temperature that the light will most closely mimic.  Because our eyes are incredibly good at adapting to different qualities of illumination, this correlated color temperature measurement is essentially “close enough” for every day life.  For example, “Warm White” bulbs are listed with a CCT between 2800 K to 3500 K, and for most purposes are similar in color tone to common tungsten-based interior lighting.
