How does the thickness of a cloud change the way it looks from the satellite?

Here is a visible image where the satellite radiometer collected reflected energy from the visible part of the electromagnetic spectrum, or 0.6 microns. A piece of this image has been extracted and appears as a square below the larger satellite image. This portion of the image contains a cloud and some clear sky areas. You can change the appearance of this extracted image by changing the cloud thickness or the surface characteristics. You do this by moving the sliding scales (scroll bars) accompanying the picture on the right.
