Description

Processing details :

LINEAR PHASE

- Unlinked Stretch

- SCNR:

- Remove Green | Amount= 0.7 | Preserve Lightness

- PhotometricColorCalibration

- Linked Stretch

- TGVDenoise:

- Using TGV mask and support

- Lightness:

- Strength= 0.15

- Edge protection= 6.89e-5 (stdDev from statistics)

- Smoothness= 2

- Iterations= 500

- Chrominance:

- Strength= 0.2

- Edge protection = 1.54e-4 ( (stdDev_R + stdDev_G + stdDevB)/3 )

- Smoothness= 2

- Iterations= 500

- MultiscaleMedianTransform:

- Using MMT Mask | 8x Dyadic layers

- Noise reduction thresholds: 10, 10, 10, 7, 5, 3, 2, 1

- First pass on Chrominance, then second pass on Luminance (CIE Y)

STRETCHED PHASE

- Application of STF using HistogramTransformation

- ACDNR Pass 1:

- Using ACDNR mask

- Lightness:

- StdDev= 1.5

- Amount= 0.5

- Iterations= 3

- Robustness= 3x3 Unweighted

- Structure Size= 3

- Chrominance:

- StdDev= 2

- Amount= 0.9

- Iterations= 3

- Robustness= 3x3 Unweighted

- Structure Size= 2

- HistogramTransformation:

- More stretching, clipping some dark/bright pixels out and adjusting midpoint to ~1/5th of the histogram

- ACDNR Pass 2: Same settings as Pass 1

- HistogramTransformation: Same as previous pass

- MultiscaleLinearTransform:

- Pass 1 & 2 - Chrominance:

- Starlet transform | 5 Dyadic layers

- Noise reduction thresholds at 1 on all layers

- Amounts: 1, 0.5, 0.25, 0.25, 0.1

- Pass 3 - Luminance (CIE Y):

- Using MMT's mask

- Same parameters as above

- CurvesTransformation on Luminance, Hue and Saturation:

- Bring out more constrast

- Bring colours out

- Shift hue a slight bit in the blues and reds

- Remove some green
