How can I take a perfect picture from a crystal chandelier? whould someone explain all tips about this kind of photography?
As a start, I would imagine you'll want a large main light source, bounced off a wall or the ceiling to evenly light the chandelier and avoid harsh shadows. Then a smaller light source in the vicinity of the camera to provide specular highlights.
This may be a broader answer than you were asking for, but my go-to reference is this book: Light: Science And Magic (Amazon.co.uk link).
Here's the link on Amazon.com
I've recently finished it, and although it is a hard read (well written by very technical), it was well worth it. It explains why certain lighting schemes work for lighting different kinds of surfaces with different kinds of reflections.
I think it would equip you with some depth of understanding about not just how to light a chandelier but why that it the way to do it.
