Topaz Adjust: HDR Dynamic Brightness
Topaz is a popular brand for “plugins” for Photoshop and Lightroom. The Lightroom version does not actually work within Lightroom. Instead a Fusion Express option is placed in the Photo / Edit In menu in Lightroom. Click on Fusion Express and you get to pick Topaz Adjust, then the image data is exported to Fusion Express, which provides a Photoshop-like framework for Topaz Adjust to use. Which means you are working with a copy of the LR image, not the original. When done with your Topaz Adjust session, you are asked to save the TA version as a TIFF file. So this is all a kludge to get around the issue that TA is not native to LR. TIFF files are bloated, this is not an ideal situation. But it works.
