About HDRI
There are two types of images. Low Dynamic Range Image(LDRI) and High Dynamic Range Image(HDRI). The first one comprises “normal” bitmaps [like JPEG, TIFF, BMP…], bitmaps which have 8 bits per pixel, with values between 0-255 [in RGB mode]. Which means that there are only 256 levels of luminosity, which doesn’t cover by far the range that can be captured by a real camera, with different levels of exposure. On the other end we find HDRI, whose values can get a lot higher then 256. The main feature is that the value of each pixel is proportional with the quantity of light on each pixel. Basically, instead of just storing colors on the screen like normal bitmaps do, the HDR format stores the quantity of light per pixel. Meaning we can have more then 256 levels of luminosity.
