From Eric at Topaz Labs:
Topaz Adjust, our most popular image enhancement tool, has been upgraded to v4 to include many new presets, the ability to handle larger images, a new user interface, faster noise reduction, and greater stability. It's completely free for existing Topaz Adjust customers. Download it here:
We would like to give endless thanks to those who offered suggestions, feature requests, and bug reports on our software. Members of both the Topaz Flickr Group and our site forum were instrumental in helping us reach the final version of Adjust 4. This is part of the reason we are able to continue to offer completely free major upgrades from day one: our community spends valuable time supporting us in our efforts, so we are extremely happy to reciprocate. Thanks again.
If you like Topaz Adjust, you might also like one of our other photo plug-ins. Topaz DeNoise, for example, is a supercharged version of the noise reduction capabilities included in Topaz Adjust, and Topaz Detail offers similar detail enhancement and sharpening capabilities without any halos. Check them out here.
Finally, as part of a intro promotion surrounding the new release of Topaz Adjust 4, the coupon code NEWADJUST will not only save $10 off a new purchase of Topaz Adjust, but will also save 20% off of any bundle purchase or Adjust->Bundle upgrade. This coupon code will expire on March 15, 2010.
Enjoy the upgrade and have a great day
