Regardless of the output type, the more image data you have to start with, the more you can use for printing. This means shooting with the highest available resolution and quality, using raw format where it’s available and shooting in colour, even though you want to end up with a B&W print. However, when composing shots you should use the same strategies as you used when shooting with B&W film: think in black and white and pre-visualise the subject as a series of tones.
