On its own this is a totally unremarkable image but it does teach us something about light and reflectivity. Each of the placemats are exactly the same color and pattern.  Because of the angle the light hits each mat differently and reflects more or less depending on the angle of the weave of the mat. Six mats, six different tones of gray.   Shot with the Fujifilm X-T2 and XF 16-55mm f/2.8 R LM WR lens.
