This started out as a photo using a 15 mm fisheye lens looking up into a bare maple tree illuminated by a pale November sky. I wanted this tree to appear to be moonlit from the upper left, but with a strong gothic feel to it. In PP, I used a vignette tool to mask out some distracting branches that appeared at the edges of the photo. Then HDR Efex Pro to even out some of the tonalities in the tree trunk, then the PS Emboss filter followed by Silver Efex Pro rendered as a tintype.
