When shooting architecture, I often bracket shots like -2, -1, 0, +1, +2. HDR looks quite fine in LR, but windows are still way to bright to look natural. Would be great if I could draw a selection along the window frames and tell HDR plugin to use the -2 shot instead.
The first thing that I would try, Ctrl j to dupicate your image so you can go back. Right click & choose create smart object. Go to Image menu Shadows & Highlights, there you can adjust: Highlights, Shadows, mid-tones, White point & Black point. Well worth a go.
