This is actually a digital rendition of wet plate, not the real thing. It certainly would be cool to do, but even just doing the digital version has taught me a lot about the real thing. There are certain characteristics about genuine wet plate that I try to make sure is expressed in my digital versions, such as the fact that true wet plate chemistry is only sensitive to blue light. Since our skin has very little blue, this is why people appear dark in wet plate images, almost like they work in a coal mine. It's also why you'll have a real hard time finding outdoor wet plate images that show any clouds, because the blue in the sky gets whited out and hides any and all clouds. This can be emulated digitally by only using the blue channel before going through the other steps of adding texture and adjusting the highs/lows to suit, etc.
Here's a larger collection of my other digital wet plate images. Disclaimer: You'll see in some of them that I bent the rule about skies with no clouds. ;-)
