While real water can be used to create this look, I preferred to challenge my design capabilities with creating the water in PS. Getting the proper image to pull it off was the task at hand!
Setting up the bottle with various light sources was the challenge. bouncing around enough light to illuminate the bottle without washing it out was not too difficult, but time consuming.
After finding the right combination of light it was time to take it LR to do the adjustments and get the image just right. PS for creating the water. Next time I will use real water to compare my work.
