Barely anyone used an explanation that anybody non-photography related would understand.
Let’s compare it to a book. You have a 1000 page book and a 50 page summary of that book. The summary is the perfect balance between detail and length. It is detailed enough for you to understand the plot of the book, it mentions every character in it, but short enough that it doesn’t take multiple days of reading, due to cutting out details that might not be too relevant. This summary will be enough for most use cases, if you however want to look for a very specific conversation between character A and B from page 781 §2, it might not be there in the summary, and you have no chance of restoring this conversation through the summary.
Raw book = Heavier, more detailed
JPEG summary = smaller, less detailed
