STEP 2
As you can see from the final image, there a lots of white tiny particles in the image which may looks like stars. So I am going to add that. To add that first I need to create a new layer and then fill it with black. To create a new layer go to layer>new>layer. You will not see any change in the image but when you check your layer panel(press F7 to open) there will be a new layer which default name is “layer 1”. You can also press ctrl+shift+N/cmd+shift+N to create a new layer.
