Hi Jeff,

I suspect that those filters you mention may already exist. I generally prefer to cook my own curves in Photoshop, so I don't pay particular attention, but here is one link to Silver Oxide filters for creating classic B&W looks.

Fred Miranda has a cheap Photoshop action that he calls 'Digital Velvia'.

As far as grain goes, Visual Infinity Grain Surgery does almost exactly what you describe.

Having said all that I've gone back to shooting film for the moment. A different kind of magic.

Best,
Helen

Digital Film Tools has an excellent set of plug-ins for Photoshop, After Effects and Final Cut Pro. These filters, called "55M", are designed to closely simulate specific real-world optical and film processing effects. I first saw them in American Cinematographer and I've been using them for a few months. They really are very effective (and intricate) tools. Most interesting, however, is that they work with both video and still imaging.
