Unified Color has announced second-generation versions of its HDR Expose software and its 32Float HDR plugin for Photoshop. The latest versions add color dodge and burn tools, and tone curve adjustment, all the while using the company's 32-bit colorspace that separates color and luminance information to avoid color shifts when changing brightness. The latest version also includes presets, which can be created and modified, to speed up the blending process. Version 2 also gains the ability to batch merge images, using one of these presets. A free 30 day trial of both the 32 Float v2 plugin and standalone HDR Expose 2 software is available.
