Turn any photo into a dot grid artwork with these Photoshop actions. You'll get great results with dots that change size. They get larger in brighter areas and smaller in darker areas. Free download available.
Now let’s create the terrain. Open file “Desert” and using the quick selection tool select the terrain only (not the sky). Copy and paste the terrain into our document. As you already guess now you should right click the desert layer and convert it to a smart object. Resize it and position the terrain as shown below. If your selection was imperfect feel free to add a layer mask and mask the
In this step and the following steps we will apply some adjustment layers to the desert layer in order to blend it better with our image. Usually almost any imported/pasted layer is often more saturated than the rest of the composition (not only in this case but in general) so let’s add a Hue/Saturation Adjustment layer and tweak with the values. We notice that the terrain looks much better if we decrease slightly the saturation. But in order to apply the effect only to the terrain layer we must clip the Hue/Saturation to the Desert layer by Alt-clicking between the two ( and we will do so for the rest of the adjustment layers applied to the terrain). If you notice the a group called City and wonder why you don’t have it don’t worry about it, you will find out why in the future steps.
Now let’s color correct the terrain a bit. Add a curve adjustment layer and use the settings shown below. Clip this layer to the layer below (it should be clipped to a Hue/Saturation layer which in turn is clipping the desert layer). Lower the opacity to 32%.
Now let’s add some selective lighting. We will make the foreground part of the terrain darker. Add a curves adjustment layer and drag the curve down to darken. Click on the layer mask and with a black brush paint on the top part of the terrain to keep it untouched by the darkening effect. Lower the opacity until you achieve a pleasant effect (40%). Clip the layer to the layer below.
And as a last adjustment layer applied to the desert create a Brightness/Contrast layer and drag the Contrast slider to the right until a value of 70 is reached. Clip the layer to the layer below.
Group the terrain layer and the all the adjustment layers we applied to it into a new group.
Now we’ll create a city in the distance. Create a new layer and press Ctrl + G to add it to a group. Name the group city and move it below the terrain layer.
First of all be careful to put all city related layers inside the group City or else we will have a messy document. Our city will have three layers of building outlines to simulate depth. First outline will be dark and it will sit in front, second will be a little lighter than the first and sit in the back of the first outline and third will be even lighter and will sit behind the two other outlines. If you followed the step 17 you should have a single empty layer inside the City group. Select this empty layer and group it again by pressing Ctrl + G. Name the group Dark Buildings. Choose the Mosque Brush and with click a couple of times using a variety of mosque buildings to create a something like I did below.
