Originally posted by carpents Actually, both of your responses underscore that for the vast majority of uses, the differences between RAW and JPEG is nil. In other words, if you're only posting the shot online or making small prints, you'll not tell the difference between a properly exposed and shot JPEG and the corresponding RAW.
carpents,
I understand that you are also using raw, so I'm not trying to persuade you of anything.
However, as a technical matter, I disagree with the first sentence, both with the "vast majority" part, and with the word "nil." As I said, the difference between 7.014293 and 7.0 is not nil. As for the words "vast majority," they aren't very meaningful. If you say "the vast majority of consumers don't need to shoot raw," I can agree with that. The vast majority of consumers don't need a DSLR, either. But let's narrow the focus down to
people who are serious enough about photography to have spent more than $1000 on their current camera and an extra lens. Moreover, let's talk not about the vast majority of these people - since there are no raw people vs jpeg people - but the
photographs that this small set of photographers take. Okay, let me just talk about myself. I just post-processed 400 images from a shoot in a natatorium where the lighting was truly awful. I can say with absolute confidence that the results I have now, while still not great, benefited substantially from the fact that I was shooting raw. Not just some of the images, not even the vast majority of them, but
all of them. I know this because the first time I shot in that natatorium, eight months ago, I shot jpeg. The photos I ended up with were unusable.
I should also point out that I disagree in part with i*Steve's comment that you can't tell the differences here because the crops are too small. He and I seem to be allies here, so I don't want to suggest that he's wrong, just that I would personally like to be a bit more precise. He's definitely right that, the smaller the crop, the less the data in either photo, and the less the data, the less range there is for difference, and I take it that was his point. And if the in-camera conversion started out pretty close to the on-computer converted raw file, well, then scaling both images down is indeed likely to produce two files that are nearly identical.
But the technical point I would like to add is, it's just a matter of percentages, and at least some of the time, if you can post-process a raw file well - say, really bringing out those subtle shading differences in clouds at sunset - the differences will remain even when you scale the images down.
It's very simple: the more data you start with, the more options you have. Some people don't WANT options. That's perfectly understandable and I have no problem with it.
