DescriptionHDR (high-dynamic-range) imaging is an innovative technique for perfecting photos. It displays a greater range of luminance levels that better represents what the human eye actually sees. With the exclusive addition of Ultra HDR, HDR Projects Professional 4 will let you perfectly capture that soft, indoor shadow, or bring out every color in a sunset. Use it as a standalone platform, or as a plug-in to Adobe Photoshop or Lightroom (plug-ins included free!).
