For B&W pics mostly tinitignan yung range of tones in the pic. You might want to adjust yung contrast to improve over all tonality. Medyo noisy or grainy din po yung pics, so kung naaadjust yung settings po ng camera nyo, lower down ISO and shoot with better lighting. Composition wise po, siguro pick a subject na lang that conveys what you want in the picture, tapos adjust for framing. Good luck po.
