There is no point in storing pixels that are brighter than the monitor's white, or in storing pixels with more accuracy than what the display can reproduce.

Most image file formats are designed to match a typical display's dynamic range: values stored in the pixels go from 0.0, representing 'black,' to 1.0, representing the display's maximum intensity, or 'white.' To keep image files small, pixel values are usually encoded as eight- or ten-bit integers (0–255 or 0–1023, respectively), which is just enough to match the display's accuracy.Īs long as we only want to present images on a display, file formats with a dynamic range of 0 to 1 are adequate. This means the brightest pixel in an image is never more than 500 times brighter than the darkest pixel. 26.1.1 High-Dynamic-Range Imagesĭisplay devices for digital images, such as computer monitors and video projectors, usually have a dynamic range of about 500 to 1. This section summarizes some of the key features for storing high-dynamic-range images. The OpenEXR Web site, has full details on the image file format itself. OpenEXR is a high-dynamic-range image file format developed by Industrial Light & Magic (ILM) for use in computer imaging applications. In this chapter, we describe the OpenEXR image file format, give examples of reading and writing GPU image buffers, and discuss issues associated with image display. When you do, it's best to store it in an image file format that retains the high dynamic range possible in the NVIDIA half type and stores additional data channels, as well. But occasionally you create one worth keeping. Most images created on a GPU are fleeting and exist for only a fraction of a second.
