I'm just interested in how you light a glass/reflective surface when you are shooting an object. I was working on a short where we tried to shoot the reflection of a character through a picture frame (glass). We tried a number of things to minimal effect.

My understanding was that you need the subject to be lit a couple stops brighter than the reflective source. Are there any particular methods of lighting for this effect? What ratios and directions do you need to play with to maximize the reflection?

Thanks,

Michael.

It's mainly about the subject being reflected having a lot more light on them, probably more than two-stops more. Other than that, it helps when you have a darker area in the surface to reflect the subject in, so plan accordingly (don't shoot your photo in the picture frame against a light background, for example.)

The hard part is not having the light on the subject look so obviously different (like a hard spotlight on the face) compared to how they are lit when you actually point the camera at the subject. At least try and keep the same angle of the key light.
