HDR Expose 2 is a standalone HDR application that allows you plenty of room to adjust your photos to be just the way you like, and helps you avoid some of those tell-tale signs that you’ve used HDR; by helping make things look more natural. 32 Float V2 is a plugin for Photoshop that mirrors the functionality of Expose 2.
Both programs have been updated with new features like Batch Merge and Batch Processing tools and a completely restructured user interface. Unified Color says that the programs are also significantly faster, which is always a nice feature for editing programs.
HDR Expose runs $149, 32 Float V2 comes in at $99 and you can get the combo of both for $199, all directly from Unified Color.
