How these pieces are realized?

Each picture is printed on Kodak metallic paper and mounted on a rigid board to appear as if it's floating.

Each mounted print is then manually  coated with an epoxy resin’s pouring, so each piece will be slightly different from the other, due to the unique effect of manual pouring. Alternatively, photos can be mounted on plexiglass, from 1/8 of inch to 1/2 of inch of thickness. I used this approach for the smaller pieces.
