Image Processing Steps:
(1) Vertical banding in raw image removed using Vicar software with long, narrow, highpass box filter, oriented parallel to banding in image.
(2) Performed moderate histogram stretch in Adobe Photoshop on Macintosh desktop computer.
(3) "Flattened" broad shading variations in scene by copying image and creating a "mask" in Photoshop with the shading inverted with respect to the original image. This mask was then merged with original scene and a second histogram stretch performed.
(4) Physically stretched image in Photoshop in direction perpendicular to the narrow dimension of foreshortened craters by 151.25% in order to approximate an orthographic view of the scene.
