One for the May: Water/Liquid" challenge. See others and join in HERE.

NOTE: This was a simple setup. Paper backdrop on a box, camera
propped on another box manually focused to the middle of the
top of the cup, set manual mode for exposure with colorful
paper reflecting light from the window, burst mode with one
hand on the shutter and the other pouring the cream and about
12 consecutive shots. I blended two of the shots in PS with
the "difference layer blending mode". Sharpen, size & post.
