sup /p/?

A lot of my shows lately have not been photo based so photo production has been low. That said I have a large photo show coming up of the artificial landscapes so I have some new ones for it. These are all 8x10 direct paper positives. I've been having some consistency issues with selenium toning so if anyone knows a lot about that process I'd love to know why. My suspicion is that the issue is insufficient rinsing but the harman paper doesn't tolerate long rinses well.
