I wanted to know if there is a difference in quality if NoiseXTerminator is used in linar state or in non linear state.
The results with NoiseXTerminator are awesome. When tested with a predefined set of stretching intensity levels, the results – for me – are identical. No matter if used before or after stretching.
For me, this means that I ll keep the denoise with NoiseXTerminator in linear state. For me it makes no sense to stretch noise I can get rid off, even if the endresult is the same.
In my PixInsight workflow I use it after color calibration (for example SPCC) and maybe some deconvolution but before stretching the picture.
