Today in class, I explained the difference between a JPEG and a Raw file. I used an analogy that I had not used before.
I explained that getting a photo from a file is like going to a store to get a brownie. You have two choices. You can buy a brownie or you can buy the ingredient to the brownie. Now the brownie you buy could delicious and perfect, just what you are looking for...but it is hard to change it once bought already baked...you can certainly tweak it, add sugur on top, break it up into ice cream and so on. But it is hard to make huge changes without destroying it. That is like a JPEG...it comes out cooked, any digital device can read it, but you can't change it too much.
Or you can buy the brownie mix, go home, use your cookware and oven and bake it yourself. Before you bake it, you can add things and change the recipe so it comes out better or just very different and it will look like a brownie, you don't destroy it. Just like a RAW file...it is a recipe, changing it is much easier and it takes longer to cook. Of course, you can change a RAW file time and time again, but once you bake the brownie, you can't change it and once you export you can't change the JPEG much either.
There is a time and place for both of them.
