Geosphere, April 2011, v. 7, p. 429-454, doi:10.1130/GES00619.1, Animation 4 - Video file of a set of 325 images of focused ion beam serial sections taken in backscattered electron mode at 25 nm spacing for sample Gothic shale 5390.8A. The horizontal field of view is 16.00 µm. The viewer should be careful in distinguishing pores from organics. Organics have a low gray-scale value. Pores are discerned by the blackest gray-scale values and careful observation of the grain-nonpore margins. Original TIFF images (1024 × 884 pixels) were compressed using JPEG algorithm at 100 quality when making the video file. Video files were further compressed by re sampling images to 400 × 345 pixels and compressing using the Cinepak algorithm at 75 quality. File size is 13 MB.
