Nice photo.. but yeah.. some blown highlights, etc. Here is my take on it:
I used a bunch of techniques:
1. duplicate initial layer
2. mask out bride/groom with Vertus Fluid Mask
3. run a gaussian blur on background layer
4. run a DFX charcoal gel filter on background layer (to darken it a bit)
5. run a DFX Fill light filter on bride/groom layer (to add some light to overall picture)
6. run Viveza to pinpoint hair on both bride and groom and add a bit of fill light
and.. tada! Let me know what you think... I think it could even do with a bit more fill light or exposure adjust on the foreground and the background could be a wee bit brighter... at least on my monitor it looks that way. Enjoy!
