I wanted to take a few silhouette photos. I dont have much experience and expensive equipment. I know that if one wants a silhouette image, the lighting source should be behind the subject. I would appreciate if you will extend on this technique or describe other techniques for shooting silhouettes. And I also have some nice b&w photos which I would like to make silhouettes of. So do you know any ways to do it in Photoshop? I will appreciate any information. Probably you know some good tutorials. Thanks.
