Descrição
Introduction
The Skydome HDRI-brand is a collection of high-dynamic range images, which displays only the sky-portion of an outdoor setting. Usually the qualities selected under the brand are cloudy and detailed skies. The lighting-condition is natural exterior lighting, with no artificial sources, and captures all spheres of natural lighting.
Description
Day clouds captured in high detail for image based lighting. Only top half of the HDRI-sphere is shot, so if using for example VrayLight with Dome-setting enabled, leave the “Spherical: full-dome” unchecked. Treeline retained for better horizon alignment.
Product Includes
Main Files
7-step 2-EV, OpenEXR and Radiance image files with massive resolution of 12679×2869. Original horizon removed, and HDR reprocessed for ghosting removal.
Backplates
A series of backplates with two sets: the ones which are corrected for horizontal alignment and the distortion caused by 8mm lens and the uncorrected pictures. And the full-resolution panorama-image also.
Other Information
Camera
Canon EOS 60D /w Magic Lantern
Lens
Samyang f3.5/8mm fisheye lens with 180 degrees of horizontal field of view.
Usage
It might be confused as to what in actuality the HDR-images are used. They are used in variety of 3D-formats to produce physically accurate lighting (to recreate the lighting conditions present in the scene which from the panorama was shot), for variety of purposes. I could say the most common usage is for achieveving lifelike light conditions to architectural renders, but also for your fantastic 3D-scenes where you want to breathe a bit of life into the images, to bring them from merely ordinary 3D-renders to the hyperrealm domain.

Note: The backplates provided are based on the images taken with the 8mm Samyang, which are then processed to remove the excessive curvature done by the lens.
