A (wo)man should hear a little music, read a little poetry, and see a fine picture every day of his/her life, in order that worldly cares may not obliterate the sense of the beautiful. (free to J.W. von Goethe)
The moment that you tilt, slant, or incline your camera to shoot your subject, you’re using a Dutch angle. Put another way, if the horizon of your shot moves across the scene diagonally, or if your audience starts to wonder if one of the legs on your tripod was shorter than the other two, you’re probably in Dutch territory.

All that is gold does not glitter, Not all those who wander are lost; The old that is strong does not wither, Deep roots are not reached by the frost ~ J. R. R. Tolkien
