This website explores the art of photography using the L.A.T.C.H. system (Location, Alphabet, Time, Category, Hierarchy). Location would be where the photograph was taken. Alphabet is listed by the last names of the photographers. Time is listed chronolgically; when the photograph was taken. Category in this case is the kind of photograph taken; from daguerreotype to digital photographs. I explored hierarchy by looking at photographers from certain time periods and listing them from the most influential in that time to the more obscure (but equally great).
