One of the most difficult things to photograph is a completely reflective sphere - an example would be one of those "mirror globes" that occasionally adorn some gardens, or more commonly, a Christmas tree ornament -- or chrome automobile hubcap. Nearly impossible to avoid the reflection of the photographer and the camera.
That can be put to good use in studying lighting .. the eye has a spherical surface and is a fairly efficient reflector. If one pays particular attention to the reflections in the eyes - "catchlights" - it is often a source of information about the lighting setup. When I get my hair cut (my wife and I have had the same `hair cutter' - hers is called a "Stylist"; mine a "Barber" - same woman - for many, many moons) I always take the opportunity to study the fashion magazines, and those books of Hairstyles, paying particular attention to the eye reflections and the effect of the lighting. Occasionally, I've even been able to see the image of the photographer, when positioned in front of a big - whumping BIG - softbox.
Softboxes are very common in fashion studio lighting - often, something like two "Halfdomes" - one above and one below the camera, or (a) LARGE square softbox/es directly behind, or to either side of, the camera. Also common are umbrellas, usually somewhat higher than the camera, and, again, on either side.
Interesting also, are the photographers tendencies to stay with one particular lighting setup. One can, fairly often, identify the photographer by her/his lighting.
The only drawback to this is the strange looks that one gets from the onlookers - No, I DON'T "swing" that way ... I'm only studying lighting when I read Elle, or Cosmopolitan ... or Hairstyling books. I'm going to make a card, stating that .. and display it when I visit "HairCrafters" with my wife.
