Shot 1 - Camera - shutter was open for 8 seconds, at which point I shone my phone flashlight to cast the shadow and light the vase itself. Aperture f/5.6 and ISO 200. Post processing - big contrast bump and darkening to the top corners.
Shot 2 - A little bonus - the shadow cast by the vase was rather intense and the further I moved the light away the bigger it got (of course) and the more intense the shape was! Camera - Shutter 6 seconds, f/5.6 and ISO 200. Post processing - bumped the contrast.
