JPG Compression Loss

I recently had a conversation with a photographer that insisted that shooting in RAW was a waste of time and disk space. I’m not going to spend any time refuting this point as it is well known that there are all kinds of advantages to shooting in RAW (from editability to data retention, etc). That said, I recently found a video that shows what .jpg compression does to an image over time. Watch closely as the image is compressed up to 600 times. Obviously there is no practical reason to compress an image up to 600 times, but it’s still interesting to see...
