Today I worked on a poster.
I started by using the select toold and selecting the ground area and trees and then went down to the bottom of the layers panel and added a layer mask.
Then I went to the layer menu and selected New Fill Layer, and selected Gradient. and then changed the color of the background by changing the hue to 210, saturation to 33, and brightness to 100.
I used to select tool and select all of the planet and copied and pasted it on my landscape and put it under the ground layer and made to the size of my liking and then changed the brightness from normal to lighten.
I then out the stars on by duplicating it from one document to another and then made a layer masy so the stars wouldn’t be over the planet.
I added the clouds by slected them, on another document, and cpoied and pasted it on to my landscape.
