What is HDRI?
It stands for High Dynamic Range Image. High Dynamic Range means that the image has a ton of dynamic range compared to a regular photograph or normal video. HDRI is often used to render outdoor and indoor scenes in 3D applications such as Maya, Mudbox, and 3DStudio MAX.
How Can I Use a HDRI?
HDRI’s are just a collection of photographs that contain additional light. HDRI’s are often used in the computer industry, to simulate the sun, light, and shadow and they can be really cool to use in a 3D scene. HDRI’s can be really helpful if you want a rusted, old metal look or if you want a really nice, bright sunset.
