As this source image was not suitable for a simple crop to 1920×1080, I decided to have a bash at using some of the more advanced features of Paint.NET to construct the wallpaper.
My previous photo editing program was PhotoImpact but I had been dissatisfied with the amount of time it took to load for a long time. However, PhotoImpact does have a number of extremely powerful features and some really useful little bits and bobs that I will miss.
One of these is the option to store preset sizes under custom names on the resize dialog. For example, I had one named “folder.jpg” which resized the image to 256 by 256 pixels. A nice little feature.
