“Raw image files are sometimes described as ‘digital negatives’ though they are not negative images, they fulfill the same role as negatives in film photography: that is, the negative is not directly usable as an image, but has all of the information needed to create an image.” ( Wikipedia)Īt the heart of raw data is the Bayer filter, which was invented by Bryce Bayer in 1976. Most photographers prefer shooting raw footage due to the high quality of images that the camera sensor could possibly produce.” ( Technopedia)
It is the unprocessed data from a camera’s image sensor. Technopedia describes it as: “the crude output of a video or still camera recording. NOTE: Here’s an article I wrote that explains the basics of high dynamic range media.Ī raw file is a direct capture of the sensor data generated by the camera. In this tutorial, I want to explain what these are. Separate from, but essential to, high dynamic range (HDR) media are raw and log files, along with LUTs.
