Topaz Adjust is one of my favorite Photoshop plugins for enhancing & cleaning up images. With Topaz Fusion Express you can now use Topaz Adjust and other Topaz Labs plugins in Aperture.

Topaz Fusion Express is an image editing plugin that runs other Topaz Labs plugins including Adjust on selected photos. Topaz DeNoise and DeJPEG can be used to remove excessive noise and compression artifacts from poor quality photos. Topaz Simplify creates art effects such as line drawings or watercolors from your photos, and Topaz Clean smoothes and manipulates details.

Topaz Adjust gives many options for enhancing images and adding stunning effects. Adjust can enhance details, contrast, color, and exposure for a more natural appearance or for extreme effects.

In this photo, I used Topaz Adjust to emphasize the storm clouds.

Other presets let you sharpen or soften details, fix the exposure, and adjust the color. You can also manipulate all of the settings manually and create your own presets.
