Wow that comparison is really cool. Looking at BPG vs original, you can see some loss of fine detail as the file size cranks down, but you can get an excellent reproduction with an order of magnitude less storage. Seems like BPG is smoothing the image a bit. For example, the space shuttle image has film grain in the sky, but BPG smooths this away.
Significantly better than JPEG at small file sizes... BPG eliminates the obvious color banding and does a much better job preserving detail.
If you set BPG to a large file size, you still get some of the noise in the sky of the Endeavor photo. But this is 1/20 the size of the original image which is incredible.
