150mm lens attached to a bellows
A laser trigger was
placed above the top of the glass with 2 soft-lights to the left and right.
A delay module was
used to adjust the delay long enough for the liquid hit bottom and start
back up the sides of the glass before triggering an electronic cable release . The backdrop was silver fabric
and is out of focus enough to avoid seeing the texture of the weave. I
often use long lenses for selective focus and when working with small
objects I find they produces a more natural perspective.
