Lay­er-lap­se ist eine Timelapse-Va­ri­an­te bei welcher die glei­chen Sze­ne­ri­en zu un­ter­schied­li­chen Ta­ges­zei­ten in­ein­an­der ge­mischt werden. Ju­li­an Tryba has such a Layer-lapse created in Boston and not less than 100 invested hours alone for filming, once more 350 Hours for the whole editing Part, while more than 150’000 edited pictures.

Tra­di­tio­nal time-lap­ses are cons­trai­ned by the idea that there is a sin­gle uni­ver­sal clock. In the spi­rit of Ein­stein’s re­la­ti­vi­ty theo­ry, lay­er-lap­ses as­sign dis­tinct clocks to any num­ber of ob­jects or re­gi­ons in a scene. Each of these clocks may start at any point in time, and tick at any rate. The re­sult is a vi­su­al time di­la­ti­on ef­fect known as lay­er-lap­se.
