The GR does not replace my Pentax K-5 kit but supplements it. I have been shooting Pentax DSLRs for the past 7 years, film for the 35 years before that. I specialize in land/city-scapes, architecture and close-up work. I stink at portraits or anything involving living, breathing stuff even if they are my own kids I have some stuff over at Flickr (http://www.flickr.com/newmikey) as well as my own website at http://mike.bing-photography.com and I sometimes blog a little bit about PP techniques at http://bing-photography.com I have been an open-source user and contributor for the last 14 years and I make extensive use of scripting to write my own raw workflows but also use a lot of image editing software with graphical user interfaces. Hope to have fun and learn here!
