Hello everyone, Is it possible scale (pixel value) only a subset of the image? I mean scale pixels under some mask. I want to scale all image except water objects. I can't make value range in band math and multiple because values are crossing in all bands ( i have 48 band image ). So i wounder before i press process button in bad math i could select spatial subset for non water area and it multiples only subset area. I tried it but it doesn't worked. I hope for some solutions. Kind regards, Skywalker
