Good morning, my name is Mark Spurling, and I am new to this forum. I am a semi professional photographer for about 20 years. I shoot with Nikon gear, and use primarily the D300s and d300 bodies. I have more glass than I will ever admit to to the wife. Besides doing the photography thing, I teach photography at a local college, and adult education center. But really my day job is computer programming. I am always looking for a good group to share critiques and ideas. I also from time to time write software for photography and like to receive feedback on that as well.
