| Dec 7, 2023 at 20:11 | comment | added | tnJed | @Zenit "Technically, it's possible of course to convert jpeg data format to raw data format" - the answer. Using another answer I was able to do it fairly easily. | |
| Dec 6, 2023 at 19:13 | comment | added | Zenit | @tnJed the answer not "why", the answer is "it's not possible". So there is no HOW. | |

Even if they are one would probably be safe to guess they comprise less than 1% of the world's camera population. ANd that's probably before you even count all of the cell phones, tablets, etc. with Bayer masked sensors. | |

| Feb 5, 2016 at 15:08 | comment | added | Michael Mauderer | Great!. Sorry the last part of the comment wasn't clear, the exact number of values vary depending on the encoding, and is mostly unrelated to the RGB channels themselves. | |
| Feb 5, 2016 at 15:04 | comment | added | Zenit | @MichaelMauderer Before edit I already had used "channel" couple of times so I chose "color" to avoid repeating :) Updated now. | |

JPEG can have only 256 luminance values per color. This is also technically wrong. I think what you meant to say is "values per RGB channel", and even that depends on the standard/compression used.

Each pixel is filtered for either red, or green, or blue. When the raw file is demosaiced colors for each pixel are interpolated based on the monochromatic luminance values of adjacent pixels filtered for the other two colors as well as the luminance values of nearby pixels filtered for the same color as the pixel in question. | |
