These mushrooms of unknown species popped up in the spring rains the other week. The main post-processing steps were to apply a blue filter effect from Aperture’s default black+white effects menu, then to apply the SEIM Silver Grains third-party effect. The SEIM effect was a free download from http://seimeffects.com. I love the silver foil look that resulted. For a larger version, see my my Flickr photo stream.
