By default, the image is displayed in greyscale, rather than
the matplotlib default colormap, 'jet'.
Images are assumed to have standard range for their type. For
example, if a floating point image has values in [0, 0.5], the
most intense color will be gray50, not white, as would be the
default in matplotlib.

In contrast, if the image exceeds the standard range, this
function defaults back to displaying exactly the range of the

If the image exceeds the standard range, or if the range is too
small to display, we fall back on displaying exactly the range of
the input image, along with a colorbar to clearly indicate that
this range transformation has occurred.
For signed images, we use a diverging colormap centered at 0.
