Here is a new shot I just finished processing, from a trip to Boston, back in August. It is a 3 shot HDR in Photomatix, then pressed in +Nik Software's Silver Efex Pro 2. After, I brought it into photoshop where I added the clouds. I play with the clouds and how its blur moves, until I get it to a more natural look and feel. After photoshop I do some finishing touches in Lightroom 4.
