May be a stupid question, but- I'm trying to duplicate a specific effect (example attached) in Photoshop. I'd call it "crosshatching," but it doesn't seem to be done using that filter. Does anyone know how you would do this- using a specific brush, perhaps?

Your best bet would be to make a series of left slant brushes and a set of right slant brushes. Then you can control the crosshatch a lot better. I know the crosshatch filter that ships with PS, "inhales sharply" (sucks), that's one of the reasons i try to do everything by hand when i can.

just my 2c

I'm not sure how to do it with a brush, but you can take a selected area, (can be solid color) and go to Sketch >Graphic Pen. Select left diagonal. This will give you hatch lines, but in one direction only. To create your crosshatch, just repeat steps and select righ diagonal this time. Hope that helps.

that would be right, forgive my spelling :P

I tried something with pre-enhancing an image and using the filter on a negative version of the image and then stacking layers on top of each other with the 'hard light' blend mode, to eliminate the greyscales. Maybe a combination with sysieqbaby's suggestion, on different layers with duplicates of the original is a way. Doing it by hand might be the best-looking method. But it takes time. Less 'sharp inhaling' ;-} results can be achieved by using filters like Indian Ink by Flaming Pear (see link), but I am not sure if the demo can be used at full.

The crosshatching filter does work, but as hoof said, you have to do it in several layers with varying transparency. Once I get the layered image done, I generally flatten the image, adjust the brightness and contrast and fool with the levels until I get a result I like.
