Skydome HDRI - Starlight Sky II

Skydome HDRI - Starlight Sky II

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

Beautiful starlight sky with a sun glowing from beneath the horizon. 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.

Resolution

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.)

Backplates

Supplied with two JPEG versions of the panorama. One in as described above in the pictures and one is the same, but it covers the whole 360/180 area.

Package includes

OpenEXR and Radiance HDR-files Both HDR-files are supplied as Skydome-versions (only top half of the panorama) and full 360/180 panoramic versions.

JPEG-backplates JPEG-backplates are provideda s well in Skydome versions and as well in full panoramic views. Both of these views are provided with no noise reduction applied, and processed backplates for minimal noise. The difference between-JPEG backplates and HDR-backplates are that the JPEG-backplates are more refined, in this case contains more stars.

Exposure

3-step 2-EV settings used via the Magic Lantern HDR-Bracketing Feature

HDR-rig

DIY no-parallax rig on top of a “basic” tripod.

Camera

Canon EOS 60D

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.
