Join Aaron F. Ross for an in-depth discussion in this video High dynamic range imaging, part of 3ds Max: Advanced Lighting (2017).
- [Instructor] High dynamic range imaging, or HDRI,…is a revolution in the way we store…and display images on the computer.…It's a way of storing all possible brightness values…in the real world.…This allows us to do things…that we couldn't do before…without incurring some costs such as image artifacts.…Now we can change the exposure of a shot…or its tonal variation after it's been recorder,…after it's been rendered or stored.…
HDRI then means that we have a lot more freedom…in color correcting or grading shots.…High dynamic range imaging also enables something called…image based lighting,…in which we can illuminate a scene with an image.…What is dynamic range anyway?…It's the ratio of highest to lowest values in a signal.…For an image, that means the ratio…of its greatest to lowest value or brightness.…So it's the contrast ratio.…
Human eyes are sensitive to…a very wide range of brightness values.…We have a contrast ratio,…or dynamic range of a million to one,…but a standard image file,…like an eight bit sRGB file…
