Just like the topic says I am looking for tips and tricks of wide-ultra wide angle shooting. Mostly 20mm and less. I haven't had a good lens to practice this with myself but do finally have one coming wednsday or thursday this week. Primarily it will be used for weddings and interior shooting this year but also some cityscape and landscape stuff. I know some of the basics of WA theory but just wondering what else is out there that I haven't heard or some interesting things to look for. Any ideas?
