LightZone is a tool for correcting and retouching your digital photos, so you can create stunning images and prints. Based on photographic principles and the Zone System method, LightZone is a more natural and intuitive approach for photo retouching, allowing you to focus on what to do with your images rather than how to do it.

LightZone provides a unique visual approach that focuses on what you want to do with your photos and not how to do it allowing you to retouch your photos in a simple and natural way. LightZone is based on photographic principles and on Ansel Adams' Zone System.

LightZone allows you to work at a higher level and focus on being creative rather than having to struggle with things like pixels, curves and histograms. Our photographic approach allows you to become proficient at image editing in a matter of hours. Use your intuition as a photographer rather than having to spend years reading books and attending courses.
