Tips for taking low key photos where the overall tone of the image is very dark, with just a small area highlighted. This can create a very moody and dramatic image.

This is an image done by using low-key lighting in color,it differences from other images because is not in black and white. like when you think of the mood you want to give out,for me black and white is more intense even sinister.The color makes it look like is overwhelmed with happy emotions. I like the effect of the technique which is Chiaroscuro. I love low key mages whether is in black and white or in color since both express different emotions .
