Here you see how a relatively flat image (bottom) was transformed into a much more dramatic image using the Spicify effect in Topaz Adjust. Also notice how the washed-out floor in the bottom image has more detail and color in the top image.
You can learn more about Topaz Adjust and other plug-ins – and get discounts on some plug-ins – at the Plug-in Experience.
While you are on the Topaz site, check out the Photoshop Bundle. It can save you a bundle!

P.S I am giving a HDR talk at the Apple Store in SoHo in NYC on April 7th. Hope you can join the fun.
