Despite having biased the exposure 2/3 stop darker, there were flares around areas with views of the bright sky. This was probably because of fungus in the lens.
So mid-tones in these areas of the image were separately darkened in post to fix the flares. Purple fringing in high contrast areas was also removed by de-saturating the magenta and red channels. My version of Photoshop Elements didn’t seem to have the option for removing Chromatic Aberration.
