The night before it was kept inside a air conditioned room that probably held about 77°F.
It was taken out maybe three hours before the shoot and was exposed to the heat all the time.
We were thinking the same, but the shapes created by the condensation almost looked like someone had pressed in the display. At the same time, the condensation keept increasing and decreasing for the next 2 hours we used it, before It completely went away.
By the way, little correction, It was maybe around 93°F outside.
