Export normal map from unity?

In unity I can create a normal map out of a black and white image (By changing the type to normal map and select create from grayscale) Im wondering if there is a way to export the normal map like it should look so I don’t need to create it from grayscale when I use it in another project?

Here’s the Image I use.

Hi there, there is a program called CrazyBump that you can create the normal In and then import them into your project. CrazyBump has a 30 day free trail so be sure to use the time wisely if you choose to download it.

NVIDIA offers a free filter for Photoshop that lets your create a normal map from any image.
