Yes, I see that now. Not sure I agree about the plane of focus but the post processing has turned the bubbles caught in the water behind the bird into strange artefacts. I did use Topaz Sharpen on the image which I normally find does a good job on both colour noise and 'pop' but in this case it has definitely done something weird to the background which I didn't notice until you pointed it out.Not sure what to think of this shot, Louis. The plane of focus is not on the birds and also weird soft spots surrounding them.
That said, it is getting a lot of positive comments in a couple of the FB wildlife sites I have posted it. 99% of the viewing public see two pretty birds and their reflections, the other 1% - photographers - see the problems!
Thanks for point it out - I'll try an alternative process to try and sharpen the birds but leave the background in its original bokeh-state.
