First Edition Dungeons

I'm trying to recreate the same look as first edition dungeons in Photoshop. I'm working slowly, because of my many ongoing projects out there, but I found the process pretty easy. Here is some detail from one of the dungeon maps of T1-4 The Temple of Elemental Evil:

T1-4 The Temple of Elemental Evil, Dungeon Map Detail

I like these maps very much. As you can see, the outline is not black, but transparent black, and most of the features (doors, columns, stairs) were hand-drawn. This is what I made this evening:

Dungeon Map, My Take

I used an old grid (which is grey, not black, and not thin enough), and a font more similar to the sample dungeon of the DMG. Design was surprisingly easy: just open a new file, set the grid, create a new level, turn the new level to black and set opacity between 70-80% (arrange to taste). Then just use the selection tool on the new level, and cut the rooms away. Add grid, numbers and features, and you are done. Yes, it's just that easy-peasy buddies. I'm working on some brushes for doors and such right now. Who said that old school maps have to be blue? Blue sucked in 80's, and still does.
