HDR is all the rage, and Unified Color has thrown their hat in the software ring. 32 Float is the company’s affordable answer as an Adobe Photoshop Plug-in. It is available now for $99.99 but I would recommend taking advantage of their 30-day free trial download to “kick the tires”. Below is the official hype from the vendor.
