The beauty of clear shiny glass.  Lighting glass requires a toolbox of gadgets to achieve the final product image on white.  A specialized surface gives the reflection in the foreground at the base of the glass diffuser. In order to keep any shadow from interfering with the transparency looking front to back means flooding the background with light and strategically placed strobe flashes. While striving for glass on white be careful not to lose the definition of the bottle. We used a number of light modifiers and redirected light as need to create this final image of lightness and clarity.
