whether you see one or more depends on umbrella placement and camera position.

the most flattering look for erotica will clone the look of natural light and be a moody sexy light, where the use of artificial light is not obvious.

and the best way to achieve this look is to shoot on a subdued lighting set, so model's pupils open up, and shoot with limited DOF to blur out extraneous detail which detracts from the shot.

some lenses can produce beautiful bokeh, some not so good, depends on iris design. (more leaves the better) but if you want really beautiful eye shots you need to use the right lens (ex: 85mm f/1.4 AFD) and setup your light correctly. yes you can use more than one strobe.

and most here would not know why the image is better, but they would say it is "hot".
