Hello! Can anyone tell me please how can i fix lumen prints without loosing those beautiful colors? First time I've tried to fix with Tetenal Super fixer (which is the fixer i use for film and it works really good) it bleached a bit the image and lost color turning ligt brownish, second time i tried to fix with sodium thiosulfate (about 100g/1Liter) but it affects the same way the image as tetenal... so, these are my questions: -am I doing someting wrong? -how many time do i need to get the image correctly fixed with sodium thiosulfate and wich is the correct proportion to mix? -Is outhere any better fixer i can use for it? -what about toning the image? before or after fixing? I´ll appreciate all your help. thanks.
