Flightline Vietnam

Heres how I created the graphic for the base I use for simulating a typical flight line from Vietnam.

For this example I created a new 640 x 480 picture in Photoshop. For an A4 sized picture in 300DPI you need a 2482 x 3510 size.

	Start with a base colour (RGB 182,182,146)
	Next add use an Add Noise filter ....
	and use a Guassian Blur filter. This will give you your base.
	On a new layer, add some basic 1 pixel lines to create the slab joints
	Copy this layer, and turn it off. Using the copied layer use a Blur More filter several times, until happy.
	Turn off the previous layer and make a copy of the original Line layer. Select the new copy lines and expand the selection by 5 pixles, and fill with black.
	Use a Guassian Blur filter.
	Turn back on the other layers.
	Add new layers for different elements you would like for example taxi lines and oil spills. The oil spills were created using different sized brushes.
	and then a Guassian Blur applied.
