These are the newly-created Civilization-Coastal-North America HDRI maps. They are available in 4k, 8k and 16k with 6 different times of day and 4 different altitudes: https://www.artstation.com/dreamcatcherhdri/store
The primary objective of DreamCatcherHDRI images is to faithfully reproduce earthly weather conditions.
Our maps scrupulously respect exposure values produced by the sun depending on the time of day. In a single image, the amplitude of exposure can range from -6 EV to +16 EV, which corresponds to earthly lighting conditions.
The types of clouds (cumulus, cirrus, stratocumulus, etc…) are recreated with their respective sizes, shapes and altitudes. Different types of atmospheres are produced with their wavelengths corresponding to the air’s density and the sun’s position. The light’s behavior in the atmosphere (translucency, accumulation, dispersion) is adjusted with care, allowing to obtain light, cottony clouds that are pearly and translucent. This photorealistic result is further enriched by esthetic choices so that our environments remain pleasing to the eye.
This rigor and demanding level of excellence are necessary in order to gurantee quality scenes for our clients.
