Hi All,
you might rfemember THIS thread on an issue which is well known to the SIGMA-community?!
Coincidently, I discovered a redicolously EASY way of overcoming any RED-Problems with such problematic RAW-files ... let's have a closer look:
Our RED-Problem ... we love it ... we hate it ....
View attachment 1700
As we know and as the histogramm clearly tells us. The RED-channel is obviously overdriven. Nobody really knows, why SIGMA's REd channel is that sensitive .... more sensitive than either green or blue-channels. The result is a large scale overdriven RED areas in the picture, that look like an ugly soup without any structures or details within. with the red channel fully driven, blue and green gain the upper hand and colours clip towards kindn of purple ... just watch it with my screenshot ... that is not, what garish red roses are supposed to look like!!
Solution is very very easy at hands!
1) Just reduce colour Saturation within SPP to an extend that the red-channel comes under control ... watch the histogram! As you see ... colours are running flat now but structures become visible ... the roses become more and more plastic! Save your image this way!!

2) Just amplify colour saturation know with any suitable other picture-processing software! Now your roses regain their bright and lively colours ... your picture becomes brilliant and develops our beloved SIGMA 3D-look ... does it not?!

3) DONE!

Do not ask me why it works ....I do not know .... but it perfectly works! Just try yourself!
See you with nice SIGMA REDs
