| Hyperfocal Design's HDRI skies allow for true realism in your renderings. Each HDRI Sky can add instant, super realistic lighting to your scene, accurate reflections, and a dynamic background that reacts realistically with semi-opaque surfaces such as tinted glass or atmospheric effects such as dust and smoke. HDRI stands for High Dynamic Range Image and each HDRI Sky has a range of exposure values from extremely under exposed to over exposed, allowing you to choose precisely the exposure or 'shutter speed' you wish. Each sky zip comes as an .exr and .hdr, and includes:
- 4,096 X 2,048 HDRI
- 4,096 X 2,048 LDR Jpg
- 512 X 256 Lighting HDRI
- 1024 pixel preview Jpg

Our HDRIs use only the best quality digital optics for crisp, clean images - we don't use mirror balls or distorted, low quality fisheye lenses. Due to the huge resolutions achieved, these images are amongst the only HDRIs available that can be used for background images & reflections as well as lighting. They provide maximum flexibility for your virtual camera and scene, allowing long zooms and extreme detail in reflection close-ups. Sky HDRIs, Advantages
Using Hyperfocal HDRI skies has advantages over using spherical environments which can include unwanted trees, buildings & other objects. Hyperfocal's HDR skies can be used in any scene, and the sky when combined with your 3d scene objects will create unique, accurate reflections. Time of Day and Weather Conditions
Browse through an ever increasing collection HDRI Skies featuring a variety of time and weather conditions, including sunrises and sunsets, cloudy days and stormy skies. Each sky is named with a 24h time stamp and sky/weather condition. Choose Your Exposure Level.
You don't even need to be using HDRI lighting to benefit from Hyperfocal's HDRI skies - one of the drawbacks to traditional sky textures is that you are limited to the low dynamic range of the single exposure level provided. HDRI sky textures allow you perfectly match the exposure level and mood of your 3d scene. Compatibility
Hyperfocal design's HDRI Skies are compatible with any application on PC or Mac that supports .hdr or .exr files. This includes all major 2d and 3d applications such as HDRShop, CS2, 3dsmax, Lightwave, Softimage and so on. |
