CommentWith this type of photo it is important to find the right shade of blue. Often cameras will underexpose sky reflections (and the sky itself) giving deep blues which are not really seen in real life. I used selective colour adjustment to significantly desaturate and brighten the blue channel, and also added some warmth to the white balance. Anyone wishing to get a handle on sky colour could start by reading Ian Wilson's 'True Blue Sky' article (2018) under Our Articles on the website.
