Unified Color has announced that HDR PhotoStudio, its High Dynamic Range software package formerly available only on the Windows platform, is now available for the Mac. The software is compatible with Intel systems running Leopard and Snow Leopard and requires at least a 2.5GHz dual core system with 2GB of RAM (4GB is recommended).

HDR PhotoStudio gives photographers control over the colours within an image, a tool set that helps them address the effects of merging multiple exposures, and an improved workflow, the company says.

HDR PhotoStudio’s 32-bit floating-point technology and Beyond RGB color space is designed to accurately depict and edit all the colours the human visual system can recognize. While the current evolution of HDR photography has often been characterized by oversaturated and unnatural-looking images, the makers of HDR PhotoStudio say their software enables photographers to provide a more true-to-life look for their HDR images.

The program’s tools aim to address some common difficulties in HDR photography. These include a halo reduction slider to fight the haloing problem of HDR images; a patented HDR noise reduction technique; the Veiling Glare adjustment designed to cut down on image haze from compounding lens glare; a Color Tone Equalizer which allows simultaneous management of saturation in six basic color channels; and a customizable recipe button to save macros.

HDR PhotoStudio supports Unified Color’s native BEF file format which enables efficient HDR image compression, so photographers can easily manage and archive the large files, according to the company. The package includes a BEF-converting Photoshop plug-in, which enables the final HDR image to be applied to a Photoshop project. The program also supports RAW files from all the major camera manufacturers as well as TIFF, JPEG, BMP, and OpenEXR formats.

Available for immediate download via the company’s Web site, the Mac version of HDR PhotoStudio is being offered for an introductory price of $100 (£63) throughout the month of February. After that, the price goes up to its regular $150 (£95).
