Look for light that catches your eye and work the scene to capture a strong composition.
You can take your photo either outdoors or indoors, daytime or nighttime, but do not set up lighting around a subject. I want you to first be inspired by a play of light that catches your eye.
Your final image should be a B&W grayscale image, but you can come to that image any way that you would like from capturing B&W in camera to converting in post-processing.
Don’t forget about proper exposure and contrast which are especially important to create a strong B&W image.
