Yesterday I was making photos at the 20th anniversary gathering of the Capital Area Flute Club based in Albany, NY. This was a combination reception and open rehearsal.
I used my 5D Mark III and EF 24-105mm f/4L lens at f/4 and ISO 800. I kept my 430EX II flash attached and turned it on some but mostly just used the ambient fluorescent lighting. The entire gallery can be viewed at http://trulandphoto.zenfolio.com/cafc20.
Here some samples:
