It doesn't affect the scalars themselves, just the colors that are assigned to them.
Say you use a red to green to blue color map, with red corresponding to -10 and green corresonding to 0 and blue corresponding to 10. Say you apply some filter or step to another timestep and your new data values change from having a range of -10 to 10 to a new range of 9 to 10. All the data now looks blue. If you click rescale to color range, the data that has a value of 9 will now look red instead and you will see all the colors along the map. David E DeMarle Kitware, Inc.
