Fine art Portarit research

Rembrandt portrait lighting is a name given to the lighting effect that the old masters used to use for the lighting effects in many of his paintings. It's basically short lighting where the shadow from the nose connects with the shadow on the side of the face, thus creating a triangle of light on the short side of the face. If nose and shadow does not connect with the cheek it's not considered to be rembrandt lighting, just short lighting.
Alot of fine art images are finished in black and white it could be suggessted that the final images portray the mood better in black and white than they do in colour.
