Second example render of PSF (Hidden Render setting in DAZ)
0 de-nosier
0 Postwork
JPG saved strait from DAZ
Night time HDR set at 0.05 at a strength of .6 (normally strength is 2 and lighting is 1)
100000 lumen light placed close to model to create drastic highs and lows.
PSF reduced noise in "low" light by 5% or so by my test...I use low in quotes as IRAY is unable to render dark areas if you white bance this image it becomes evident compared to 3delight
