Monochrome

def monochrome(pic):
  for pixel in getPixels(pic):
    value = (getRed(pixel) + getGreen(pixel) + getBlue(pixel)) / 3
    setRed(pixel, value)
    setGreen(pixel, value)
    setBlue(pixel, value)

def sepia(pic):
  for pixel in getPixels(pic):
    value = (getRed(pixel) + getGreen(pixel) + getBlue(pixel)) / 3
    setRed(pixel, value)
    setGreen(pixel, value*0.9) # These values are just rough. You can make the toning warmer or cooler by fine-tuning them
    setBlue(pixel, value*0.7)    # We make the picture warmer (reddish/yellowish/brownish) by reducing blue and green, not increasing red
