Hi Binnur,
Yeah, I am going to blame my almost complete lack of photography over the last couple of years on
that one
It's good you have not done the same (so far) - but beware!
I'm afraid I am another in the 'less (saturation) is better' camp, which you've already addressed above, so we'll agree to differ on that (in the nicest possible way).
Have you tried using ACR as a Smart Filter (in PS CC) and using the individual colour gains panel?
To my eyes, the most unrealistic* parts are the very red colours associated with the edges of the sand at shore and tree lines, plus a few other areas, I was thinking that bringing down the Red and/or Orange sliders might help somewhat.
* However, do bear in mind that I was not there and I could be totally mistaken, perhaps it really is that colour.
Cheers, Dave
