       | For computers and Lightroom/Photoshop you have stuff like
       | Replichrone to help.

       | I almost always add a subtle amount of "grain" with LR when
       | developing photos. It looks pleasant and seems to add a sense of
       | coherency to an image. I find that in many cases where details
       | are lost to aggressive NR or otherwise simply not present, grain
       | can make it easier to "see" the missing detail... as with most
       | things, the optimal amount of noise is not zero.

       | I rarely add grain to images, but when I do, it can sometimes
       | give a more-organic and hence perceptually-real feeling.

       | There are image-software companies whose specialties include
       | careful emulation of grain. I don't use them, but plugins like
       | https://nikcollection.dxo.com/silver-efex-pro/ are intended for
       | that very purpose.
