Last of my shots from Yallingup reef.
Originally there was a lot of green fringing and little purple fringing around the outlines of the rocks in the foreground. I removed this easily in Lightroom, but it seems to have left behind a slight halo. I think I may have to have another go of processing this in the near future.
