As most of you probably know Adobe recently introduced new algorithms, I call them Al Gore rhythms, to enhance the resolution and size of images. Currently it is accessed through Camera Raw under enhance. The super resolution tool enhances the total pixels 4x. It's pretty impressive for subjects that require a big crop. I looked through my endless files of bird photos and worked with some that I liked but were a little out of an ideal range.
Enhanced
I've been having a little fun with the raw details and super resolution tools in camera raw. I was able to get a little more cop out of some "not quite close enough" bird photos. Accessing these tools is a little strange but google will send you to the adobe help that explains it all. Hope you enjoy.
