craig bass Posted April 4, 2012 Share Posted April 4, 2012 Hello everybody. The question I am about to ask may seem a bit naive, but as I am self taught in the art of lighting (and still very much a novice) I was hoping that someone would be kind enough to help me out. My question is: how can I simulate a light coming from a practical source in frame (say, a desk lamp) without A) lighting up the fixture itself; B) casting a shadow of the fixture; and C) motivating the direction of the shadows. This far I have been attempting to shine a beam in the same direction as the practical, from behind it. This always causes the practical to cast a shadow, which is ridiculously unrealistic, as no light casts a shadow of itself in such a fashion. In addition, I generally end up lighting the practical itself within the beam, causing it to be too "hot" or "lit". I am attempting to work with a scene where a lamp is right next to an actor on a desk, and cannot seem to figure out how to make this work. I could shoot from down low, so as to try and skip the fixture, but, considering the resulting "monster movie" appearance, I am pretty positive this is not a method employed with any frequency. Again, any help is appreciated. Link to comment Share on other sites More sharing options...

robert duke Posted April 4, 2012 Share Posted April 4, 2012 use a heavy diffusion on the lamp and flag it off the practical. Link to comment Share on other sites More sharing options...
Kevin Horn Posted April 16, 2012 Share Posted April 16, 2012 I apologize if I read you incorrectly, but you're trying to motivate light from a practical desk lamp correct? And your problem is that when you set up a light it's too hot or directional, creating an unmotivated shadow? Key your subject with a china ball/100w bulb and throw a dimmer switch on it. This will give you a soft, shadowless key replicating what a desk lamp would bounce off of a desk onto your subject. If that doesn't work for you try using that practical lamp to bounce off the desk into your subject's face (assuming you're lighting a person at a desk). White paper on the desk would work great for a practical bounce. Wood also looks great as a bounce, so if your desk is wooden then try just simply bouncing off the desktop.
