@michaelricheson: Fun set up here. first I had to cut out the bottom of the bottle so that I could actually pour the liquid through it into the glass. Then I had to set the glass and the bottle up using stands and clamps to hold everything perfectly in place. Then I had to get my composition, my lighting and everything else completely dialed in. After the shoot was over, it was over to Photoshop where I had to merge four separate layers. Zero AI was used.
