What an unprocessed photo looks like
What an unprocessed photo looks like: Dec 27, 2025 (Photography) Here’s a photo of a Christmas tree, as my camera’s sensor sees it: Sensor data with the 14 bit ADC values mapped to 0-255 RGB. It’s not even black-and-white, it’s gray-and-gray. This is becuase while the ADC’s output can theoretically go from 0 to 16382, the actual data doesn’t cover that whole range: Histogram of raw image The real range of ADC values is ~2110 to ~136000. Let’s set those values as the white and black in the image: Vnew = (Vold – Black)/(White – Black) Progress Much better, but it’s still more monochromatic then I remember the tree being. Camera sensors aren’t actually able to see color: They only measure how much light hit each pixel. In a color camera, the sensor is covered by a…
