A height field would probably be a better choice for someone first
experimenting with either. Though it has an extra step of rendering a height
field and then using the resulting image in your final render, it is still
generally faster. Also, if you want to move to an isosurface for quality
reasons later on, can't you just use the pigments used to generate the
height field as a function for your isosurface when the time comes?
