Question for all you experienced sx50 users
I decided to take some time today and play with some manual settings. So I reviewed Kenn and Temple Threed's blog at kenn3d.wordpress.com. He listed his settings for shooting manual and of course had some beautiful shots. So I tried to get as close as possible to the same settings and went out to find something outside to shoot. It was about 4:30 pm. (I could not get the iso to go as low as his, but got as low as I could.) There was a great egret on the pond behind our condo and a turkey vulture on a roof top. Ken stated he likes to be as close as possible. I was not able to get closer than approx 100-125 ft to the egret and the vulture was directly above on the roof of our neighbor's 4 story building. I was so disappointed when I down loaded them to my computer and saw that the majority of them had a purple fringe/halo around them. I googled that, but could not find a cause. My settings were iso 160 f /6.5 and ss 1250 and full 1200 zoom. I stayed in the same spot but of course the egret moved while catching his fish. Over half of the images had the deep blue/purple fringe. The same for the vulture.
Can someone explain what causes this fringing and how I can avoid it in the future. It did not appear when I viewed them in the camera. I have also experienced green and pinkish fringing in the past as well. I usually shoot in scene mode with HQ burst, sport mode, and Tv mode. sometimes I have experienced the same problems in those modes as well.
thanks in advance
