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.
Beautiful starlight sky with a sun glowing from beneath the horizon. Whole HDRI-sphere is shot, so if using for example VrayLight with Dome-setting enabled, use the “Spherical: full-dome” checked.
Massive resolution of 12272×3472 allows the sky to be rendered directly from the viewport with considerable detail (tested with up to 8000 pixel wide renders.)
OpenEXR and Radiance HDR-files. Both HDR-files are supplied as full 360/180 panoramic versions.
JPEG-backplates JPEG-backplate is provided in full 360/180 panoramic view.

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.
