What is the best way to handle overexposed sky in post-processing?
I know, a photographer should generally try to not shoot against the light and take care of proper exposure. Still, as an amateur I frequently end up with "white skies", where there is no color detail at all in the sky. This can be because of shooting against the light, simply chosing the wrong moment, position or any other reason.
Yet, given such a result, which is better avoided then cured, what is the best way to post process such a scenario? A full image exposure correction (I shoot in RAW) darkens the foreground too much, so it seems selective exposure correction is the way to go. That however can be very tedious in complex images (imagine a complex tree on a white background) and I've found results to be unnatural.
Is there a better way to filter / postprocess these white skies?
