This effect was generated in Filter Forge, a Photoshop plugin that allows you to create your own filters.
Crosshatch and Stipple is a stylisation filter that gives you the look of certain kinds of etchings. You control the balance of highlight, midtone, and shadow in the etching, as well as, separately, in the colour underlay, if you turn on that option. You can also adjust the hue and saturation of the colour underlay.
NOTE:
"Size, pixels": This ever-present slider is below the regular filter controls. Smaller values gives you a finer texture (i.e., smaller, more tightly packed lines or dots), but the control can be a bit twitchy. Certain values look great, even if they aren't even divisions of the maximum value, but others produce terrible moire effects. Just play around with things and see what you like. ^_
"Colour Depth": This is basically colour posterisation, which I thought worked with the stylisation effects of this filter. Low numbers produce pretty abstract gradients, but as you turn the depth up, you get more colours and a more realistic look.
