When shooting for black and white, expose to crush the shadows and blow highlights deliberately. Midtones are the enemy of drama. You want graphic, stark, contrasty frames.

Look for scenes that are already high contrast - bright sun, deep shade, neon at night, flash-lit faces against dark backgrounds.

Watch for: busy midtone scenes that produce flat, grey, uninteresting monochrome. If there's no strong light-dark separation in the scene, black and white often isn't the answer.

The point: black and white is not just colour with the colour removed. It's a different way of seeing.
