Hik­ing offers many oppor­tu­ni­ties for land­scape stereo-pho­tog­ra­phy. Due to the diverse scale of the objects, from small, beau­ti­ful flow­ers, to trees, to entire moun­tain regions it is pos­si­ble to take a large vari­ety of stereo-pho­tos. My favourite stere­os are the hyper­stere­os of moun­tains. But with base­lines this large (rang­ing between 5~100 Metres), there are mul­ti­ple things (clouds, peo­ple and mov­ing shad­ows, cast by clouds, or even the earth­’s rota­tion) which make this type of stereo-pho­tog­ra­phy chal­leng­ing. But with some prac­tice a pho­tog­ra­ph­er can devel­op meth­ods to counter these phe­nom­e­na, and once you do, the results speak for themselves.
