Need help with Photoshop removing sunspots/glare

This is a very tricky thing to do and its going to take a lot of work and finesse to do that.  D Fosse is right on the money about how to get this right.  But even then,  you're going to have to do something to bring color back in the area shown in his photo. 

This looks to be a scanned image. Was it scanned from a slide, a negative, or from a print?

In the fogged ares, the green channel looks pretty decent, except for some loss or

fcontrast. The blue layer has much greater loss of contrast, and this extends into the woman's arm and dress, as well as further down into the brick pavers.The red channel has gotten inverted, and the problem continues even further towards the bottom than the blue channel.

I would try three separate curves adjustment layers with a radial gradient in the masks, and try to get the fogged area to look as good as possible. Then judiciously paint on the masks with a soft brush. I say three layers, since each one would need a different mask.

This is really difficult, because there is no color information left in the pink area. There's nothing to restore, you'll have to rebuild.

That's not to say it's impossible, nothing ever is, only that it will take time. I'd start by desaturating the affected area and rebuild the color using gradient map layers, applied locally with soft masks. You'll need a lot of layers, each masked to a local area.

I played with it a bit just to see what could be done. This is not finished, but about at the point where you could start recoloring. I'm already up to 10 or 12 layers here, each masked, so there's no point in showing that.

If it is an important image, get someone who's good at this. It can be done.

Or of course, just turn it into a black and white.
