Close-ups of the centers of the two Apollo 15 Panorama Camera images which were used to create the Defense Mapping Agency's topophotomap of Ina. The ITEK Panorama Camera's field of view is 10.77° (horizontal axis in the above image frames). Close-up Panorama Camera views of Ina. These views have been reprojected as if Ina had been at the center of the Panorama Camera's field of view. These images then were enhanced and adjusted so that the surrounding terrain has similar brightness and contrast in order to reveal the differences in albedo within the caldera due to the different emission angles of these two images.

The above image is a clearer version of the stereogram shown in the Apollo 15 Preliminary Science Report. My new stereogram reveals that features within the Ina caldera exhibit striking changes in albedo with changing emission angle. A remarkable amount of depth and detail is visible in these 3D anaglyphs which I created from the above reprojected images.
