Wanted to share this video with you as is truly relates to my project Fra Vestfjorden.
The compositorial retrograde technique used by i.e Johan Sebastian Bach literally means "backwards and upside down". Fra Vestfjorden was composed by the shape of a mountain from a photo found online. As a photo you would be able to flip it and look at it in four different ways. The right way as you photographed it (prime/1.), backwards (inverse/2.), upside down (retrograde/3.) and upside down backwards (retrograde inverse/4.).
