i dont spend much time in photoshop actually using filters. almost everything i do in photoshop is menus for Encore, and most of the creativity i use is almost all content aware related with after effects and general video work. i have a general understanding on how to use PS though.
I would start with Image>Adjustment>Threshold, and explore the look with the slider. Perhaps a hint of Noise would be good too.
Good luck, and nice to see you over here.
