Here is an Example of water drops (fake) on the high resolution image
Steps 1-4 shows how to create the basic water drop outline
From 5-13 We learn how to give the light and dark feature to the shape by applying a linear gradient
14-18 we see how to add the shadow outside and inside the water drop
19-23 we shall ad the little white tiny glowing and shining speck 🙂 It makes a lot of difference. I used Brush tool and then added outer glow to it.
24-28 we see how to change the shape of the water drop by Liquify tool brush
Finally a summary of the progress as you learnt above
I just added this Spherize option based on suggestions from “shuiichiro” and “owen248” and “elussich”
There might be many information which might not be necessary in the tutorial but I just mentioned them for the newcomers sake.
