What the camera captures is "real.  The camera sees the world very differently than we do.  Our eyes have far greater capabilities than any sensor on the market today.  Every sensor is restricted in its ability to capture dynamic range, colors and tonal gradations compared to what we see.  In addition, every manufacturer tunes a camera's sensor in a way they feel makes the camera perform better, not more realistic.

If you want realistic or even naturalistic, you're often going to have to do some processing of the image whether that's something like a RAW file in Lightroom or a carefully setup processing of JPEG files in your camera.
