I've been reading about Vue 5 and what it can do with HDRI images in terms of matching the lighting of the scene to that of the image. This all sounds very exciting but the one thing no one says is what exactly is a HDRI image and how is it different from any other kind of image ? Is it something I can create with just a regular camera ? Is there a good place to shop for these images online and can I find more variety of these then just ones of skys ? Hoping somebody here and demystify the process! :) Thanks!
