Nik Vivenza is a cool little tool for making adjustments to photos. It is similar to Lightroom in that there are a bunch of sliders that you can play with to fix up the photo and make it look beter. However, it has one cool feature Lightroom doesn't have, control points. In all photo editing software it is easy to change everything in the picture, but what if you just want to change one portion of the photo. That is where control points come in, they offer an easy way to make adjustments to only one portion of the photo. I must say, I really like the feature, it is possible to do something similar in Lightroom and Photoshop but it is just a lot easier. There is a 15 day free trial on the Nik Software website if you are interested in trying it out.
I usually use Nik Vivenza with other plugins so the photos don't have a distinctive "look". Here are all the photos I have posted where I have used this software.
