Beauty Photography is a whole new genre in itself, and deals mainly with lighting the model’s face and hair. It is important to understand how to light to emphazize cheek bones, jaw line etc. Since beauty shots are mainly tight close ups, one most important factor is the catch light in the eyes. Some photogs don't care about it, some go creative with it by using strip lights and ring flash, and some prefer a nice circular catch light. For those who prefer the perfect circle, say hello to the Beauty Dish!
Lets see what a beauty dish is. A beauty dish is a round and semi flat dish campared to the standard reflector and usually comes in medium and large sizes depending on the light company. Simply put, its a light modifier in the shape of a dish, used for lighting beauty shots. Normally, the large size is around 36″ in diameter, and the dish inside is usually white but some companies also make them in silver. You can use it by simply mounting on the light, or you can diffuse it like the softbox.
