right so what info from the raw does it take if it ignores all that?

It takes the raw data read from the sensor, and it can also read the white balance.

so exposure settings?

Yes, raw processors can read the metadata stored in the raw file, and that includes the values of the f/stop, shutter speed, etc. as recorded by the camera. But even if third-party raw processors are able to read the metadata regarding camera settings, such as contrast, saturation, sharpness, etc., they generally won't do anything about it, because each camera manufacturer does things their own way and not according to a standard. Also, some metadata may be unreadable by third-party raw processors.

However, there are a few cameras which do use the standard DNG format for raw files, and presumably all of the camera settings are honored by third-party raw processors that support DNG.

A common use for shooting raw is to *not* use the camera maker's idea of color rendering and image processing, or at least do something rather different.

please explain?

If you have a Canon camera and you like Canon colors, then you can shoot JPEG and always get Canon colors. But what if you have Canon camera and don't want the Canon 'look'? Or suppose you want to heavily manipulate your photos in a way that isn't natively supported by the camera? Or suppose you don't have the time to get all of the JPEG settings exactly right? Raw shooting gives you as much flexility as possible without having the look determined by the camera maker. Or suppose you use various cameras during a photo shoot and you want the output to look as similar as possible, and so raw shooting and using a third-party raw processor can make everything look similar.

But most camera makers also supply raw processing software so that you can duplicate the camera JPEG 'look' while still having greater flexibility in processing.
