Can anyone give me some pointers... I'm doing a free job for a school!
Whats the best settings for dark skinned people. Want them to have perfect shots!!
When I was an AV producer working for a yearbook company, I was often sent to schools to photograph a range of, well, everything, for their prima donna yearbook advisors. Candids, classroom activities, sports, etc. — I got it all. I knew how, because I grew up doing it in high school in the 1970s.
Later, in the mid-2000s, I was training school photographers. I went to a lot of trouble to write a manual on it, including spending several days at my kids' elementary school taking pictures for their memory book, which my wife was editing. So here's my formula, used a decade ago but still relevant:
Fluorescent lighting in schools is USUALLY from ubiquitous 2'x4' ceiling 'troffers'. If you're lucky, they all contain the same brand and type of fluorescent tubes... usually Cool White (4100K to 4200K). Those are actually heavy on the green part of the spectrum. If you're REALLY lucky, they use Daylight tubes (5000K). They're easy to work with. But whatever you encounter, you're going to average them together with a gray card and custom white balance.
To get the exposure and color balance right, I would carry a Delta-1 gray card and do a Custom White Balance on my Canon. (It's called a manual or preset white balance on some other brands.) Your camera manual will tell you how to do that. The procedure differs from brand to brand.
I first put the camera into 100% manual exposure mode. That means NO auto ISO, and manual aperture and shutter settings. With a 28-75mm f/2.8 zoom, I'd set my shutter speed to 1/60 at a minimum, and to avoid fluorescent light flicker, 1/125 at a maximum. (I know how to hold a camera very still, and use a monopod when I can.) I used ISO 400-800, because any higher on that old 20D or even the 50D I used would be too noisy. I used f/2.8 to f/4, because the lighting in schools is remarkably similar from room to room. I used NO flash.
Next, I would set the meter to center-weighted mode and meter a gray card in the light falling on my typical subject. Then I would adjust the aperture for the correct exposure readout (+/-0).
Finally, I would do a custom white balance, using Canon's two-step procedure for that. I would use that combination of manual settings to photograph everything I needed to in that same light. I might chimp a bit (review images on the back of the camera) and adjust slightly if part of the room were darker or lighter, but that would usually not be necessary. I worked in JPEG mode. And I did little, usually no, post-processing.
Now for the secrets to photographing dark people and objects. You can photograph anything or anyone black or dark toned, but to get a detailed image, you must make use of "specular highlights" — reflections of your light sources. Drum this principle into your head:
The size of the light source, relative to the size of the subject, determines the size of the specular highlight, the size of the diffuse highlight, and the shadow edge "acuteness" of the image. The larger your light source (think: completely overcast sky, or 7-foot umbrella), the softer the image, and the more light wraps around the subject and creates specular highlights. On an overcast day, the specular highlight and the diffuse highlight will have about the same value. On a bright, sunny day, there will be harsh shadows, small specular highlights, somewhat larger diffuse highlights, sharp demarcation between highlights and shadows, and the shadows will be around two f/stops darker than the highlights.
In very specular lighting, such as direct flash from an on-camera strobe, African Americans tend to have a "soot and shiny chalk" look that they hate. In diffuse lighting — soft light that wraps all around them — they have a nice, soft, rounded tone. Classroom, lunchroom, library, and general office lighting in schools is nice and soft, and just bright enough to use with good results.
Back to the cafeteria:
If the lighting is reasonably soft and uniform, as I think it will be, you should have a light that is flattering to African Americans. The trick is to nail down that exposure and white balance. DO NOT use auto white balance or you will see lots of variations in color in the same room, as it reads brightly colored objects or clothing and tries to make them gray...
