Re: One misunderstanding

From the article:

"As if the above points weren’t enough, what has to be one of my favourite reasons for shooting in RAW is that all image editing is non-destructive.  Unlike a JPEG file, where any changes made to the image are permanent, all changes made to a RAW image are stored in a metadata file associated with the RAW file, leaving the original file untouched.  This means you can never irreparably ruin an image by saving some mistaken changes and also you can go back to an image a few weeks, months or years later and reprocess it, from the original RAW, as your processing skills improve."

The smart jpeg-shooter leaves the original unaltered en save the processed image as a copy. As such jpeg is not more destructive than raw.

Non-destructive means that you don't loose tonal information in the picture, often leading to solarization in a print and irreversible. There are a lot of non-destructive techniques to work on jpeg pictures in photoshop.

After raw conversion what counts is not the original raw format but the outputted format. And it is as easy to create a destructive result with a raw convertor.

A good reason to shoot in raw is not only that you can reprocess later with improved skills (you can do that also with your original jpeg picture) but that you can reprocess it with new and better versions of raw software. You can't update image processor in your camera.
