For this series, I wanted to create images that had an antique or deteriorated look. Nosing around with Filter Forge, I found several filters by the same developer that offered various ways to create old style maps. This was a great starting point, but the images were still too clean looking for what I had in mind. Blending in textures of rusting surfaces helped enormously. Various adjustment layers and tweaks to the blending modes in Photoshop finished everything off.
