Now and then I experience 'Camera Error' messages in my Sony alpha 77ll. I can not reproduce it, but it often happens on longer exposures. Normally I just have to shut down, remove the battery, and all is fine again.
But sometimes the programm jumps into the in-camera-picture-effect-mode "watercolor". I did not notice it for a while. And now I like it. Probably only, because I have nothing else today.
