Do you know Kolor ? Kolor is a small photography software editor based in France near where I was born, in the Alpes. They are doing great panoramic photographic softwares like Autopano Pro and Autopano Giga, probably, to me, the best panoramic software on the market today, a software that is permanently enhanced by a programmer team that listens to photographers to feel their needs. In one of the latest update of Autopano (2.5), they added a nice tool which removes the haze of landscapes. This is a powerful feature that works really well and allows photographers to get simply better images with higher contrast. Today, they take this filter of Autopano and launch it as a plug-in for Photoshop. Neutrahazer is now available for Photoshop CS3, CS4, CS5.5, CS6 and Photoshop Elements 8,9 and 10. The plug-in is sold for €39 (around $52).
Neutralhazer is cool because it can work in auto mode pretty well, but can also offer some editing and masking tools. It can detect the air density of each pixel that will allow Neutralhazer to guess where the foreground is if you want to concentrate the effect on the longest distances. It often reveals small details that you would not see before thanks to the enhanced contrast (smart contrast) that gives Neutralhazer as a plug-in.
