In the fourth version, a new tool for creating a photo album with a large number of templates appeared directly at Lightroom. The received photo albums can be directly sent to Blurb to print them using the new Book module. A new tone range processing technology has also been implemented, which will help more accurately transfer sections of light and dark tones. In addition, video support was expanded, with a direct loading of them to Facebook services✴ or Flickr. Videos can now be edited directly in the program. There is also the possibility of local editing of the picture plots using the Noise Reduction and Moire tools.
