The HDR Efex Pro Software from Nik Software is a software plug-in for use with Adobe Photoshop, Adobe Photoshop Lightroom, and Apple Aperture. It allows you to create stunning High Dynamic Range (HDR) images by blending multiple exposures of the same scene. The software is optimized for use with multi-core CPUs.
HDR blends an underexposed image, a properly exposed image, and an overexposed image together in order to create a stunning image that preserves shadow and highlight detail. This software gives you many options for creating HDR images, including one-click visual presets, advanced tone mapping algorithms, detailed HDR controls, and U Point technology for fine-tuning colors and tonality.
