Ylläs – auringonlasku kesällä 2019 (gtlvideo.py-demo)


Tämä on ensimmäinen time-lapse -video, jonka olen generoinut koodamallani gtlvideo.py-ohjelmallani (versio 0.911). FHD-video on demo. Video on tehty 49 CR2-kuvasta, jotka on ensin muutettu PNG-muotoon ohjelmallani. Kuvaustiedot: Canon 7D + EF 24-105mm f/4L
