For the other one, first add a Channel Mixer layer, check the "Monochrome" checkbox, then enter 0/0/+100/0 for the four sliders. This will turn the whole photo black-and-white.
Then add a Levels layer and immediately clip it to the Channel Mixer layer. Enter these values:
R 0/1.10/235 and 30/255
G 0/1.05/235 and 15/255
B 0/0.90/255 and 15/255
This will now turn the whole photo kinda brownish.
Return to the Channel Mixer layer and invert the mask to hide everything. Then with a big soft brush, paint loosely over the flare area.
