Working with a negative from 2007 of a Brugmansia bloom just starting to open up. I printed one print with a 0 contrast filter and the the other with a 2.5. Same exposure but I notice how the details in the shadows are not visible in the higher contrast print. I might try dodging the shadowed area a bit and printing for a few extra seconds with a high contrast filter like a 5 to give a blacker black. Here is a link to the first print I made using a glossy paper with a higher contrast filter made using my condenser head.
