Detailing on the ceiling of the Russian orthodox Uspenski Cathedral in Helsinki, Finland.
This took me too long to process, there were some washed out areas due to sun coming in through the windows. I tried to use the power of HDR to eliminate it, it helped but it wasn’t sufficient enough. So after a couple of hours in Photoshop with the clone stamp tool (along with some others) I managed to get my wanted look.
A single shot HDR processed in Photomatix, heavily touched up in Photoshop CS4 and finally adjusted in Adobe Lightroom.
