About the Author: Sean Nel
Sean has been shooting since schooldays (started with a borrowed Pentax K1000 from His sister, also a photographer) but only became seriously involved with photography when he returned from living in Eastern Europe. While overseas he did shoot some non-profit editorial work and also made the big switch from Nikon to Canon. Today, Sean likes to shoot Stock. "Stock is the 'best of both worlds' industry, that requires creativity and very set guidelines to be successful..." Sean also teaches photography (basic, advanced & other Stock-related courses) and frequently arrange "shooting days" for photography clubs and individual groups.
