Change overexposed white sky to blue
Hi,
I'm struggling to fix the sky in one of my photos. The photo is overexposed, so the sky is 100% burnt white (there is even a weird white/grey stripe pattern in it, but I don't know if that's lightroom or an artefact of the camera sensor.)
I made a perfect selection of the white sky, however all the adjustment controls (including the coloring) have no visible effect, because the area is 100% white I presume. What can I do to fix this?
