Tutorial: AKVIS NatureArt

Night Sky

Mysterious and unexplorable, the night sky has fascinated humanity since time immemorial. Using the Night Sky effect in AKVIS NatureArt, you can imitate the beauty of the night sky on any image: add scattering stars, iridescent nebulae, or impressive meteor showers.

Night Sky Effect

The effect will be applied only in a selected area! Use the follow tools to make a selection:

  • Star Zone . Use this tool to mark areas where stars, meteors, or trails should appear. You can change the tool\'s size in a pop-up window which opens with a right mouse click in the image window.
  • Nebula Zone . Use this tool to select the areas where the nebula should be added to the other objects. You can change the tool\'s size in a pop-up window which opens with a right mouse click in the image window.
  • Eraser . Use this tool to erase selection areas. You can change the tool\'s size in a pop-up window.
    • Hint: To get a straight line, draw a line while holding down Shift.

 

In Settings Panel you can adjust the parameters for the Night Sky effect:

Common Parameters:

  • Base Color. This parameter sets the default color for all objects. Click on the plate to open the color selection dialog.
    \"Base
    Base Color = White
    \"Base
    Base Color = Red
  • Fading (0-100). When increasing the parameter, the brightness of stars, meteors, trails, and nebulae gradually decreases at the bottom of the selection.
    \"Fading
    Fading = 25
    \"Fading
    Fading = 75

 

Select objects that will be displayed in the night sky by enabling the check-boxes: Stars, Meteors, Trails, and Nebulae. Adjust their parameters in the appropriate tabs.
