Mike Verta seemed to think that the grain wasn’t original to the prints, and in his comparisons the Blu-ray grain is quite a bit larger and has much more color noise than the Tech grain. The increased contrast of much of my grade can make the grain appear more severe, as well as raising the brightness. The binary sunset in particular is unusable without noise reduction, simply because I have to brighten it so much.
I use Adobe Premiere Pro CC for this project.
