An album includes a front cover panel, a back cover panel, and a spine panel extending between the front and the back cover panels edge-to-edge. The dopant density in the heavily doped n-type ring is preferably 100 to 10,000 times the dopant density in the cathode. A transparency value for each of the plurality of windows is determined based at least in part on the respective distance. The emulsion preferably contains an oxidatively dimerized form of a mesoionic compound having a thiolate structure, and a silver chloride content of at least 90 mol %.
