I used the original 12f125.blu, 12f125.grn and 12f125.red images from the NASA Viking image archive, converted them to .png, merged them into one image (almost matching true color; see here for the channel mixing process) and decreased the brightness by 25 and increased the contrast by 80 (see Mars Viking 12f125.png for a version without the brightness and contrast changes). Except for the conversion, this was done in Adobe Photoshop CS2. The original file by NASA is in the public domain, and so is this new one.
Other versions I created this image as a replacement for the image Viking Lander 1 Phobos Shadow p131b.jpg (see also here). This file was created by NASA, but the quality is not very high. Using the original pictures from the Lander archive resulted in a higher quality image.
