This application has a modern interface, where you'll be able to see the image on the right and the menus on the left. Photivo has a large amount of tools, filters and utilities to edit photos. All you have to do is explore the options and check the different effects available.
Photivo allows you to customize the interface to adapt it to your own liking. Another interesting option of Photivo is that you'll be able to send the enhanced image straight to the GIMP image editor, to keep on working with it. You can also change the size of the photos to adapt them to be used on the Internet on a website.
There are many tools and options available for free with Photivo.
