Also, increasing the overall saturation isn't effective, and won't make your image "better." You need to take saturation into account for every color you choose. In this case, you have a really great opportunity to take advantage of something called atmospheric shading, which is shading based on distance. When things get further away from you, they lose saturation, because there is a ton of air between you and it. Also, they get more blue, because the blue wavelength of light penetrates earth's air the best. So the macro shot should have the most saturation, and it should fade to less saturation and more blue (and eventually black) as the picture approaches space.
