Render time 0:05:23. Adaptive 8-64 samples per pixel. Mitchell-Netravali Reconstruction filtering. Halton 2,7 for AA. Halton 5,3 in circular coordinates with inverse CPD for DoF. Here, I generate a set of 4 random numbers for each pixel. I use these random numbers to shift the Halton sequence (with wrap around).

Adaptive sampling 8-128 SPP, Halton 2,3 for AA and Halton 5,7 for DoF. Render time 0:10:45. Causes some areas to "stand out" (no blur). I suspect this is an issue with Halton sampling, where the low number of (minimum) samples (8) sometimes erroneously have a low sample variance in colour. I can fix this issue by either changing the minimum to 16, or doing the "random perturbation" as described in the first section.
