4K film grain overlays

A grain plate has to be at least as big as the frame you put it on. If you scale grain up, the specks turn soft and blurry and the effect looks fake. The 4K plates below are 3840 px wide, so they cover a 4K video frame or a large photo at 100% without any upscaling.

For stills from most cameras the 3000 px plates further down are enough. They are the same grain, sorted from fine ISO 100 to coarse pushed film.
