1. Shoot in RAW
Of course shooting in JPEG doesn’t stop you shooting in black and white – but if it’s an option, give RAW a go, you might be surprised by what it offers you in post production.
2. Shoot in Color
If your camera doesn’t allow you to shoot in RAW – shoot in color and do your conversion to black & white later on your computer that you will have more control over results.
Shoot with the lowest possible ISO possible. It is particularly important when it comes to black& white where noise created by ISO can become even more obvious.
4. When to Shoot
Many digital photographers actually prefer to shoot images for Black& White in low contrast situations. So a dark or overcast day can be a great time to shoot out door shots.
You need to train yourself to look at shapes, tones and textures in your frame as points of interest. Pay particularly attention to shadows and highlights which will become a feature of your shot.
