How black and white is computed
Each pixel is converted using the standard luminance weights (more green, less blue), the way the eye perceives brightness. This keeps skies, skin and foliage at natural tones instead of the flat gray of a simple average.
Sepia and negative
Sepia gives the warm brown tone of old prints. Negative inverts every color, useful for scanned film negatives or design effects.
