In Photoshop, open the image that could use water drops. We are going to be using quite a few palette and blending options and later, the liquify tool.

Make a new layer. Use the Elliptical Marquee Tool and make a selection on the new layer. You do not have to draw a perfect circle; what water drop in nature is a perfect shape?

Next, choose the Linear Gradient Tool and draw from the upper left to the lower right of the image, until you have an approximation of what you see here. Deselect.

Change the blending mode of the layer to Overlay. The selection then becomes mostly clear. Using the brush tool with a setting of 6 and color set to white adds a nice touch.

Now it is time to add the special effects. From the bottom of the layers palette, choose drop shadow with the following settings:

• Blend mode: Multiply
• Opacity: 50%
• Angle: 153

For a better overall effect, use inner shadow with the following changes: Angle of 153, Distance of 2. For a little extra, utilize Inner Glow with Blending Mode set to screen and the default color changed to black.

Duplicate the layer and use Edit > Free Transform to add a new and smaller (or larger) water drop.

Here, we have duplicated the layer once again and utilized the Liquify Filter (Filter > Liquify) and the Forward Warp Tool to make a myriad of different shapes.
