Add Vibrancy to an Image With Photoshop's Liquify Filter

I started with a photograph of a vendor shack on colorful South Beach, Miami Beach. While I liked the composition and the brightness of the image, the colors needed punching up, there were a few distracting details, and I wanted to enliven the image.

First I dealt with color. I duplicated the layer, chose Image > Adjustments > Hue/Saturation, and increased the Saturation to 65. I then applied Filter > Blur > Gaussian Blur with a Radius of 20, set the blending mode to Multiply, and flattened the image. To lighten the shadows, I chose Image > Adjustments > Shadow/Highlight with a tonal range of 40. For a softer sky, I adjusted the Blues in Hue/Saturation, setting the Hue to –13, Saturation to –45, and Lightness to 25. To bring out the clouds, I chose Image > Adjustments > Replace Color, selected the clouds with the eyedropper, decreased the Fuzziness to affect only the clouds, and increased the Lightness to 75. I now had beautiful glowing color.

I chose Image > Mode > 8 Bits/Channel, then chose Filter > Liquify. I used Liquify’s warp tool (or the Forward Warp tool in CS) at a large Brush Size to go over the image once for a broad warped effect. (Using a Wacom tablet and pen makes it easier to get the control you need in Liquify.) You can also paint with the Reconstruct tool to restore an area to its original state. Use a small brush for speed and a more precise undo. To start over completely, click the Reconstruct button (or Restore All in CS).
I chose the Liquify filter again to do another pass of warping. This time, I used the Freeze tool at a large brush size to mask areas I didn’t want warped. Use the Thaw tool to undo freezing, choose Invert to reverse masked areas, and choose Thaw All (None in CS) to erase a mask completely. I then used the Warp tool with a variety of brush sizes to delete distracting details at the edges of the picture near the horizon, essentially dragging them off the picture. The Warp tool only affected the unmasked areas. Note: In CS, you can mask by clicking Mask All under Mask Options with Show Mask checked, then use the thaw mask tool to unmask areas you plan to effect.
I applied Liquify one more time. Using the Warp tool at a small Brush Size, I warped the stripes on the shack, warped the clouds in the sky, and “plumpened” the two shacks.

The final image, shown at left, gives the feeling that the shacks are almost alive and moving.

TIP: For a more unpredictable effect in the Liquify filter, choose the Turbulence tool at a large Brush Size, and hold the pen over an area to gradually increase its turbulence. Or try the Shift Pixels tool (Push Left tool in CS) at a small Brush Size—dragging your pen up pushes pixels to the left, dragging down pushes pixels to the right, dragging to the right moves pixels up, and dragging to the left moves pixels down. Also try the Bloat tool to swell the area the pen passes over, or the Pucker tool to contract the region under the pen.
