I still need to do the PP on the photos, but just wanted to comment on the difficulty I had. I went to a local figure skating event and was worried of the low lighting conditions. At first, I was attempting to shoot on Aperture Priority mode. I found shutter priority was my best option. I was able to get acceptable exposure with my ISO set at 800 f 4.5 to 5.6 on my 55-300mm lens with the shutter usually set to 1/60sec.
It was a nice challenge to put what I've learned to the test. I look forward to sharing some of those pictures here with you.
