OpenEXR - продвинутый формат изображений, специально разработанный для компьютерной графики и приложений, использующих технологию HDR. Такой формат способен поддерживать несколько слоёв структуры изображения, а также несколько форматов сжатия, в том числе сжатие B44 и сэмплинг Luminance/Chroma, использование которых обеспечит сильное уменьшение файлов в размерах без видимых артефактов изображения.ProEXR - плагин для Photoshop и After Effects, который позволит работать с форматом изображений OpenEXR и насладиться всеми его преимуществами.
OpenEXR is the advanced floating point image format created at Industrial
Light and Magic and the best format to use when working with 32-bit HDR
imagery in Photoshop and After Effects. However, Adobe's support for the
format is minimal - only with ProEXR can digital artists finally access all the power available in OpenEXR.
OpenEXR can support multiple layers of imagery, but Photoshop can't read or save layered EXR files...unless you have ProEXR. Store all your layers in one file and read them into After Effects, Nuke, Shake, and Fusion. Or in one step save layers as individual files for programs that are less EXR
savvy. ProEXR will also read all the image buffers created by modern 3D
renderers and place each in its own Photoshop layer.
ProEXR lets you choose from all the compression options available in
OpenEXR. Most EXR compression is lossless, but one of the most interesting
options is a lossy method similar to JPEG, applied to the world of floating point. Using B44 compression and Luminance/Chroma sampling, HDR images can be crushed to a fraction of their uncompressed size, usually without visible artifacts, only in ProEXR.
Other ProEXR features include:
* Retention of EXR color space information.
* Support for both 32-bit and 16-bit floating point.
* Full control over alpha channel processing.
* Automatic EXR project set-up in After Effects.
* Built with the latest OpenEXR libraries.
* Free, open source After Effects plug-ins for working with OpenEXR
files and 3D Channels.
