Description

Real film grain is not a random distribution of noise.
A realistic grain simulation depends on image dimensions, is different in highlights and shadows and different depending on the film one would like to simulate.

Proposal is to add a filter that adds realistic film grain with presets of different choices.

History

#2 Updated by Joe Giampaoli over 2 years ago

I can agree with this. I always add grain to shots especially if I'm going to print them, I don't print much but that's pretty much what I do. I found the "Add Grain" module film emulation by David Tschumperlé in GMIC/GIMP to be quite effective, especially the Orwo-NP20-GDR and the way it merges it (grain merge), it looks very realistic and nice. But having different ISO modes is also really nice the way it's on DT.

Maybe something similar to it?
