This will be short post. As from now, one of the best software for editing photos (entire collection) is free and can be downloaded from google nick software dedicated page. I tried almost every editing software and app available, and this one is simply the best and unbeatable. Collection can work as plugin for adobe lightroom and photoshop, but can also work as independent application.So download it and give your photos professional look, and all that for free. Thank you google!
Here is download link;
