Brightening can be applied only to an image. Raw is not an image.

A digital image (as opposed to a film or a print) is an array of numbers with X, Y coordinates representing brightness levels at each point. Usually there are three values for each point, for the three primary colours.

A raw image is also an array of numbers stating the values read by the sensor at each X, Y point.

It is just as much an image file as is a TIFF or a GIF. JPGs could be regarded as corrupted image files.
