For this retro portrait of Tia, I placed a Westcott Spiderlite
TD5 with five 23w fluorescent bulbs 3 ft from her on camera right.
A medium (24x32") Westcott Box was attached and the internal
baffle was used to soften the light more and spread even illumination
to the light bank's corners. A 32" Sunlight Westcott
Illuminator reflector was placed on camera left to bounce some,
but not too much, light into the shadow side of the model's
face. While the Canon EOS 20D can shoot directly in Sepia mode,
later on I used PixelGenius' (www.pixelgenius.com)
PhotoKit Photoshop compatible plug-in to add a brown tone to the
finished photograph. Since many of the still images from the movies
in those days were made with a soft focus lens, I added soft focus
to the portrait with B+W's software (www.schneider-kreuznach.com/
filter_e/software_filter.htm) Soft Focus filter.
The RGB spikes of output from high-color fluorescent light closely match the
receptive RGB spikes of a CCD imaging chip. A CCD is least sensitive in its
blue channel and tungsten light has the least output in the blue, and when combined
with the effect of infrared output (mostly heat) it can overcome the chip's
entire spectral response. What about CMOS? It's difficult to generalize
a head-to-head comparison between CMOS and CCD image sensors, but assuming competent
engineering and optimum settings for white balance, exposure, and light levels,
image quality from CCD sensors should be similar to image quality from CMOS
sensors, at least in terms of color accuracy.
Comparing fluorescent continuous light sources to tungsten lighting is a lot easier. Fluorescent easily comes out the winner when compared to tungsten, which is 93 percent heat and 7 percent red light. Techies who want to delve deeper into light and color should visit Osram's Encyclopedia of Light (www.osram.com/service_corner/glossary/index.html).
What does this mean for digital photographers? It's simple: The light you used to hate, you can now love. Making all of this easy for us and wrapping these fluorescent lights in a useful package are a trio of digital lighting kits from three different manufacturers that can change the way you make portraits.
Westcott's Spiderlite TD5 is designed for still and video image-makers and works with either halogen or fluorescent lamps. The halogen lamps produce a consistent but hot 3200Þ Kelvin and the fluorescent lamps are rated at 5100Þ Kelvin, although that varies as the lights warm up. After using a color meter to set the exposure, I found my Canon EOS 20D produced better results in Auto White Balance mode. Your chip may vary...
The all-metal Spiderlite TD5 has a built-in speed ring for attaching a light bank and three separate switches that let you use multiple combinations of the lamps. A handle allows quick and easy rotation. The fluorescent lamps provide smooth, continuous light so that all of my exposures in this session were made in (gasp!) Program mode. I used the digital SLR's Exposure Compensation feature to increase exposure in 1/3 stop increments by looking at each image file's histogram on the camera's preview screen to make sure exposure was balanced.
Check Your Ego At The Door
From the mind of Gary Regester comes the Lowel Ego, a tabletop fluorescent soft light. Setup is a breeze: plug it in, place it on the table or light stand, and turn it on. The Ego comes with two 27w screw-in compact daylight fluorescent lamps that have a 5000-10,000 hour rating. Their Color Rendering Index (CRI) provides a more natural and realistic color balance than standard (color-me-green) fluorescent lamps. Lowel includes a hinge-folded white bounce card for reflected fill. It can be used for portraits but is also useful for making tabletop shots by eBayers, archivists, and desktop publishers. The Ego can also be used for webcam desktop video conferencing.
When using the Ego light as a main light for portraits, be sure to place the light as close as possible without getting it in the shot. Because of its small size, the Ego light is probably best suited to headshots and that's a good thing. I used to hate setting up lights for headshots; it took too much time fiddling to get the light looking like I wanted. The Ego sets up quickly and when used with a reflector, such as Westcott's Illuminator placed close to the subject on the other side of their face, makes an ideal headshot setup. I like doing headshots again and never thought that would happen!
I do a lot of shoots with new and inexperienced models. Big, complex light banks attached to electronic flash units distract from the mood I try to establish, so the Sunpak digitLITE 600, which is basically a cold "hot light," is a great setup for these kinds of portraits. The light is solidly built and easy to move around if your light stand has casters, and creates the kind of working environment that helps the model relax and be at her best. The digitLITE 600 uses cool fluorescent tubes that are balanced for daylight and do a good job of emulating the real thing.
I use a digitLITE 600 as a main light or as a beauty light placed below the model's face, in ways I formerly used a reflector back in the old film days to create the kind of look that requires the least amount of gear possible. There are photographers, like my wife Mary, who shoot with available light, but what she really means is "every light we have available." If we had 20 lights in the studio, she would use them all. The work would be perfectly gorgeous but I hate to schlep all that stuff. That's why the Sunpak works so well for my "shoot-and-scoot" style of photography.
Product Photographs Made Easier
The Sharpics D-Flector is a unique reflective background that activates when photographed with a flash. The result is a picture with a clean white background with the object appearing to be floating on air. Used with these fluorescent lights, the D-Flector is a literal "background in a briefcase" that is perfect for professional photographers, web designers, or anybody who wants to document inventory or personal possessions. It's also ideal for making photographs when selling merchandise on eBay.
