I recently discovered a wonderful plugin at PhotoPlus Expo for Lightroom and Photoshop called Athentech Perfectly Clear. It is also available as an app for mobile phones.
The software corrects each individual pixel of an image, and the results are impressive. It can adjust for color balance, exposure, contrast vibrancy and noise. The best way I can describe it is that it removes the grey quality of digital files, and does it quickly. What I like is that the default settings give a great result so it really can speed up your workflow. And if you want to get under the hood, you can tweak it even more. It's great for the photo-enthusiast and working professional as well.
My only complaint about the plugin is that it works directly on the file. I wish it would create a duplicate layer like some of the Nik plugins so you could blend the original with the plugin version.
The overall takeaway, though, is that this can be a great timesaver and enhance most every image you shoot. Highly recommended.
