Join Ben Long for an in-depth discussion in this video Exploring nondestructive editing, part of Exploring Photography: Shooting in Raw Mode.
- In a non-RAW image file like a TIF or JPEG…or Photoshop document,…every pixel in the image is represented by a number…that corresponds to that pixel's color.…It's actually represented by three numbers,…one each for the separate red, green, and blue channels,…but for the sake of this discussion,…we can get away with calling it a single number.…When you make an edit to an image,…the numbers corresponding to the affected areas…of the image get changed.…When you save the document, those new numbers are…written into the appropriate parts of the image file,…replacing the numbers that were there before.…
The old numbers and corresponding old image…are lost forever.…In this way, editing is destructive to your original image.…When your RAW converter processes a RAW image,…things get a bit more complicated.…The original RAW file has one set of numbers,…but after performing RAW conversion, your computer…is now holding a different set of numbers.…A set of numbers that have been processed…to represent a full color image.…
