Gradient Smithy allows, among others, to realize what photoshop calls gradient map effect. Clearly, the plugin uses any gradient to associate to every level of Luminosity a colour. Furthermore, Gradient Smithy allows to create first complex Gradients, quite easily.
Features:
-Mode creation is mode by default. In this mode very few options are available.
-When you go into the application mode, the plugin possesses in memory, the gradient you just have created. If it is not the case, the plugin automatically proposes one.
-From application mode to creation mode
When you return in the creation mode, the last gradient in memory is lost! So be careful, and save your work.
