Currently, grain size is absolute. Grain size relative to image dimensions would be a great idea. Theoretically, the grain size would also adjust relative to cropped dimensions much like the post-crop vignetting works.

grain size is subjective and why would it change based on a crop?

Actually, it seems grain size is absolute. Sometimes we want to apply an equal amount of grain to photos, but a setting size of '25', for example, will look smaller on a 22MP file than it will on a 10MP file.

When i say it's subjective, im referring to the initial decision about appearance...

And yes, grain size is absolute, so a setting of 25 will look the same, regardless of pixel dimensions. If i'm not mistaken, the size slider is a direct translation of pixel size, so if you have an image which is 1000x500px, a setting of 25(px) will have the exact same grain size as an image which is 5000x2500px... they'll both be 25px.

I would really like to have grain size same for all size when export. I don't understand why grain is not 1:1 when resize pictures on export? If I have nice grain on 1:1 preview in full res and then I export photo in 1024px size, grain is gone. It doesn't make sense!
