RAW is like a dream. I love it, love it, love it. I love it so much I wrote it three times.
Seriously, it's so much easier to work with Raw. You can improve the image a lot without messing up the integrity of it.
Think of it like this: You know how when you have to peel tape off a surface or a sticker off a window? Well, Jpeg is a nice-looking sticker, but everytime you get a corner up and start peeling, it breaks off. Very frustrating. RAW is like pulling up a corner, and as you peel you worry about it breaking, but it just keeps peeling until you get it and you think, "ahh, that was awesome."
Okay, bad analogy.
Try this: It's like cooking with a high-grade gas stove vs. a cheap electric. With gas you can fine tune the heat and make changes to the heat quickly and accurately, but electric is frustrating because you're literally creating an overflow in an electrical current, which will only get worse if it doesn't slow down, so the stove is constantly changing temperatures and making it difficult to do it right.
Still a bad analogy.
Oh well. I can't get it too well. It's just that RAW lets you do a lot to fix the photograph. Fix isn't even the right word all the time. It's a way to create a look. It takes longer, but it's worth it.
Here's evidence for you: Ken Rockwell says shooting in RAW is mostly pointless.
So shoot RAW.
Thank you.
