Yes, this doesn't look too severe. We can certainly fix it.
Go ahead and do your raw processing (don't forget to fix the colour space) then post the photo again, and we'll discuss the flare fix.
No, they'll be in tabs across the top. Try it and you'll see.
Yes, but that's not the most efficient way to do so. We can work slicker than that.
