I am only trying to display a technique for crushed blacks really. And I wanted to move on to blown highlights I hope it’s helpful to people.
DNR is a different beast all together. I don’t know any tricks for that. I’m not sure weather this would also work to make something not look not like plastic or waxy or smooth with DNR. I would say you have to find a different version without it but here mixing the 2 as a whole image might take some of that away by making it simply opaque.
