But does this make us extremely lazy in the way we take pictures, heavily relying on the raw file to save images, or should we have really thought about the image before taking it and adjusted it?
In the shots of the "Bubbles" above you can see that sometime thinking about it leads you to quite a different direction than an in camera Jpeg.
First you must realise that there is no such thing as a scientifically correct exposure. It is always a choice. The camera makes a choice in producing a Jpeg... but it has no idea about the effect you are aiming at, so it uses a preset. It then throws away all the information that it did not use and make a compressed Jpeg. This may or may not be what you intended, but within fairly close limits that is what you are stuck with.
Working in raw is not only a different type of file it is also a different way of working. You can get back to basics. if you want to get technical you can measure the darkest and lightest tones you want to capture, and make sure that they are covered by the exposure you set and the brightness range your camera is capable of. You need not bother to set the white balance as all the entire colour range will be captured.
So when you start to process the picture you know that all the data that could be captured has been captured.
As you process the picture You usually find that your raw software has read the camera settings( that would have produced a Jpeg) and has set the various sliders accordingly. From that starting point you can change all the parameters that are available, you can change the exposure the overall contrast, the local tone contrasts of highlight or shadow, the lightness or darkness of the highlight, mid tone, and shadow regions. The white balance overall, in the highlight and in the shadows. you can change the sharpness and the noise structure.
As in the days of film you have complete control of how you envisioned the photograph to look.
You can save the processed file in any file format or size you fancy. Your raw file remains unchanged.
If you save the result as a Jpeg you have simply saved a different choice than was preset in the camera, neither is
more true than the other. both used the same methods to make the chosen settings... one was made by the firmware writer in the factory the other by yourself.
Different camera firmware writers/cameras and sensors produce different results.
Every shot starts life as a raw file
You can chose to use either, or save in other formats that give you even more later options. The choice is always yours.
Raw is not about saving images it is about making choices.
