Destructive editing is more or less improving your image by manipulating pixels of the digital photograph. When making changes to the photograph as a part of the editing process is considered “destructive,” making changes permanently to the pixels. When manipulating an image for example: when darkening an image or area of an image, the pixels within targeted boundaries will be altered to become darker. Whenever the image is saved. the subjected pixels will be written into the image permanently and can not be returned to their original state. Hence, the term “destructive editing” since the original state of the pixels are considered to have been destroyed.

Lets say you have a photograph and cant choose between either a colored version or a black and white. There can be destructive editing and can be considered non destructive because of working on different layers, instead of working on the original layer. Nondestructive lets you export two copies of the original photograph, one in color and the other in black and white. There are various advantages of nondestructive editing like image quality, flexibility, and preservation of the original data. Preserving the unaltered state is for future edits, on the other hand if the original data is edited permanently then there is no return.
