"With Fine mode be carefull when take Hi-Res while doing landscape with vast horizon, better take Nor or Low -Res."
I do not understand this, please explain
Hi Kibs, this phrase I expressed my opinion about 1 of the most annoying problems of Foveon : posterizing/banding.Ofcourse other brands camera can suffer it , but this phenomenon especially does a disturbing effect on an almost perfect Foveon's image, even it can destroy the1st good feeling of that picture.When one does a landscapes with bright cloudy sky and ample water surface, you'll see in the details magenta patterns called posterizing/banding, I personally don't get enough explanation about it , but it really appears on every Foveon's pictures.The posterizing/banding elimination in PS is another time- consuming process and do blurring never becomes a radical aproach.Sigma PP provides a perfect solution for that : noise reduction, with 2 clicks on chroma and luminance
you can eliminate this annoying effect.But this feature only for RAW format .X3F, and the new SPP 5.3.2 can do that at ISO 100 when the olders only at ISO 400.If you shoot .Jpeg and set it in FINE mode, the higher resolution you choose the sooner you 'll get posterizing/banding and noway to eliminate it in SPP.
