From grubbasoftware.com:

TrueGrain is a pro-grade tool for accurately recapturing the aesthetics of black and white film with digital photography.

With TrueGrain, you can:

Accurately recapture the aesthetics of particular film stocks--including "lost" films--while retaining an all-digital workflow

Creatively employ credible film aesthetics

Add high resolution film grain information to digital images to elegantly minimize the pixilation effects of upsampling

Match digital imagery to existing film images for restoration and compositing purposes

If this works as advertised then we are as close to digital looking like film as we've ever come. To some, that is a step backwards, but to those who still have a stash of Ilford in their freezer this is like the second coming...of film.

Anyway, I'm trying to secure a review copy.

Check out their site for more info, I will be looking into this very closely over the next few days.

UPDATE: In my excitement I somehow missed the DEMO download. Getting it now...
