Hey, what's the best or correct way to calculate an image's luminance, effectively converting it to grayscale, but preserving its relative brightness?

Use the weighted sum of the colour values...
L = 0.3R + 0.59G + 0.11B
Or are you looking for something more sophisticated?
L = 0.3R + 0.59G + 0.11B
