Mars Viking images

I created several images based on the original Mars Viking images that NASA released. The images in press releases and the images you see on the web are generally not the best quality you can get. Therefore I decided to use the original source files and produce some better results, which are displayed below. See the pages of the images for more detailed descriptions of how I did it.
