Objective was to preserve the sky colors without manually masking - poster was not comfortable
with manual masking.

1. Use magic wand to select sky in blue channel (max contrast, hence max selection chance)
2. Feather selection by 1
3. go to main image, create an automatic layer mask with created selection
4. use shadow highlight to fix everything except sky
5. apply local curves in the water and planks for pop
