may trick dati na ganyan sa film, ung 2 images of urself in one picture... hehehe the beauty of owning a DSLR.. sobra dami options! 
iba un, multiple exposure naman un. Hirap timplahin nun kz pag nagkamali ka, ghost image ang lumalabas instead of a solid superimposition. Eto, 3 separate images na pinagdugtong. Nagcompensate lang for exposure changes on the 3 images :)
