Is the example image (https://github.com/worldveil/photomosaic/blob/master/media/r...) with or without opacity cheat?

Both! You can experiment with —-best-k and —randomness <1.0 and sort of get things in the middle.

Basically what this will do is assign each tile less than 100% of the time randomly and then for each that isn’t, you choose among the top best K matches on L2 distance with equal probability. Gives it a little bit of both.

I'm talking about `--opacity` - because to me the mosaic images used in the sky can't be that blue originally.

[muzakthings]

Right. The opacity setting is superimposed after the tile assignment. Thus you can have both.

I’ve found that opacity if 0.7 is often a nice compromise.

Yeah that's using opacity, e.g. there's an image of a blue horizon that gets tinted red.
