Shadows change and shift as the sun moves across the sky. We've all seen our own shadow stretch away into the distance on an evening stroll and we've also seen the hard flat shadow that welds itself to the ground right beneath our feet under a hot midday sun. Many of these images are from our abstract tutorial and that shows how shadows bend and alter our perception of reality. Our shadow IS us and yet it isn't. Play around with this idea as the sun climbs and then dwindles.
Decide if you want to include the object/subject in the picture as well - or just shoot the shadow
