HDRI-Studio Intros HDRI-Studio Lighting EnvironmentsProfessional photographic studio lighting for 3D computer graphic models (November 12, 2004)

With HDRI-Studio, designers, illustrators and animators can achieve the ultimate in photorealism, free from the time consuming hit and miss of traditional simulated lighting techniques. They can now concentrate on exploring the different camera placements with the 360-degree interplay of real studio lights, soft boxes and colored gels, with minimal effort.
HDRI-Studios high-resolution, full spherical maps integrate seamlessly with most 3D programs (Cinema 4D, LightWave 3D, Maya, SoftImage and more) that support the Radiance (HDR) format, and provide the full intensity of studio light sources to give artists the ultimate in realistic lighting.
HDRI-Studio environment maps were developed "of necessity" by London-based computer graphic artist Peter Crowther because, "There was nothing that could easily reproduce realistic studio lighting for CGI. I get a lot of requests from clients who want the image to look as if it were a real object photographed in a studio.
?I spent a great deal of time researching the options available for using high dynamic range images for lighting computer generated models, however, there were no environment maps available based on real photographic studio lighting. There are plenty of landscapes and interiors that are used as illumination, but these tend to produce incongruous reflections in an image thats meant to look as if it was shot in a photographic studio.
A photographer lighting real objects, has the benefit of real time feedback. A computer graphics user has to wait for the computer to render the image and, the more realistic the lighting, the longer the time it takes to process the result. Because of this fundamental difference, photographers light objects in different ways.
The idea was essentially to produce a set of lighting solutions that had the photographers lighting skill built in. Working with experienced still-life photographers in several photographic studios, they would light a series of real generic object types under various lighting conditions some gelled, some neutral remove the objects and capture the lighting. They used high dynamic range imaging equipment, from SpheronVR, to capture the lighting intensity in a full 360˚ sphere in a single pass for superior quality.
From those images, Crowther developed the HDRI-Studio range of environment maps. These apply real-world illumination effects that can be rotated 360 degrees, with adjustable luminosity, for endless possibilities. "I need balanced studio lighting that looks completely natural with any product and produces a professional studio look with anything I am working on from a palm-sized product design to a moody bottle shot or a sleek automobile image. I believe that HDRI-Studio environment maps are the only way to achieve such naturalistic effects."
HDRI-Studio environment maps are available via quick delivery web page ordering. They can be downloaded in four product categories and in a variety of resolutions. Neutral, for standard "soft box" lighting, Gel, to add hue, Abstracts for creative reflection mapped environments, and Automotive, which is specially designed to correctly capture motor vehicle lighting. The automotive set will be available within two months from launch. Visit http://www.hdri-studio.com for ordering information.
HDRI-Studio images are available in four Resolutions and three License types. Single User, SME and Corporate.
