The end result is an 8-bit image where you should be able to see lots of details that might otherwise be lost in a regular photo.

The idea is to take several photos with different exposures, and put them together so that all partsВ of the image areВ properly exposed (not too bright or too dark) вЂ“ for example the sky is usually much brighter than the rest of anВ image, so the tonemapping software will choose a darker exposure to use for the sky and a brighter exposure for the rest of the scene to balance it out.

вЂњHDRвЂќ photo, not an HDRI by our definitionДЄlthough many cameras and tutorials refer to this as an вЂњHDRвЂќ image, this type of image can be better described as a tonemapped image. To illustrate the difference between a JPG and an HDR file, all we need to do is play with the brightness: Luckily, there are several formats that can do this, the most common of which has the extension вЂњ.hdrвЂќ. If you want to light aВ 3D scene using an image, what you really need is a format that can store more than just 8 bits of data per channel so that you can haveВ a much larger range of brightness. The problem with LDR images is that they are limited to a relatively small range of brightness, from 0 to 255, which is not actually all that much. An example of an LDR image is a JPG file. They store 8 bits of data for each of the red, green and blue channels for every pixel. Most photos and images in general are what I call вЂњLDRвЂќ images, or Low Dynamic Range images. вЂњDynamic rangeвЂќ is the measurement of how much brightness information is contained in an image, so a вЂњhigh dynamic rangeвЂќ image is an image that has a very large range of brightness, more than you can see on your screen in one go actually. вЂњHDRIвЂќ stands for High Dynamic Range Image. If youвЂ™re already confident that you know what an HDRI actually is, scroll down to the вЂњCreating an HDRIвЂќ section.ДЄnВ HDRIВ is a panoramic photograph that covers the entire field of visionВ and contains a large amount of data (typically 32 bits per pixel per channel) which can be used to emit light into a CG scene. This is by no means the only way to make an HDRI, but it is a good introduction to the process.Д«y the end of this tutorial, youвЂ™ll have made your very own 360Вє HDR environment map that can be used to light a 3D scene.Д«uckle your seat belts boys and girls, because this is gonna be a long one!Д«efore we actually get into making anything, itвЂ™s important to thoroughly understand what it is that weвЂ™re doing, and demystify some of the confusion around the subject. IвЂ™ve been making HDRIs for a couple of years now, so I hope I can save you some time and experimentation. One mistake like using the wrong focal length or choosing a slow shutter speed can mean all your time has been wasted and youвЂ™ll have to start all over again. Not only do they provide accurate lighting, but they can be seen in the background and in reflections, which makes them all the more immersive.Д¬reating a high quality HDRI from scratch is quite a complicated task that requires very specific equipment and a meticulous workflow. They are essentially snapshots of the real world that contain exquisitely detailed lighting information, which can transport your bland CG objects into realistic virtual environments. There is no easier or quicker way to light a CG scene than to use an HDRI. A simple 3D scene that was lit using only the HDRI above (no additional lamps)
