No reflector were used.
The aim -shared with the chef- was to avoid any confusing and uninteresting stuff like plate, glass, cutlery and show the chef's will to stay with fresh and natural ingredients, while used the restaurant garden as "the background".
We both were referring to the innovative use of a sheet of glass which both reflects the food and allows us to see through it too!
Have you used a reflector ? I think you have...
Also very nice. Romain made good use of the limited shooting time, by integrating your high resolution images for the slow pans, and actual video for the 'floating' ingredient effects. His musical underscore is also fitting.
Thanks for sharing,
