The first thing you need to do is to open the Empire State stock image in photoshop and duplicate it. Name the bottom one ORIGINAL and the top layer TOP-LESS. Now you have to erase the top part of the building on the TOP-LESS layer but leave the sky visible. The easiest way to do that is using the Clone Tool (S) and the Patch Tool (J).
Start with the clone tool and hide part of the building as shown above. Use the sky surrounding the building as cloning source. When you’re done with the Clone Tool you will see that some edges are not well blended. That’s because this tool don’t blend the luminosity. To solve that problem use the Patch Tool.
The patch tool is similar to the clone tool but it also tries to match the luminosity of the source and destination so that you get a seamless blend.
When you have the Patch Tool selected, activate the Source option on the upper settings bar and select the area that contains the miss-blended areas and drag the selection over a clear area of the sky. When you release, the patch tool will replace the area with the sky sample where you dragged the patch.
If you don’t know how the Patch Tool works watch this great video found on You Tube.
After hiding the indicated areas with the Patch Tool, this is how the image looks. We are still working on the TOP-LESS layer.
As you see on the picture above, the smooth area must be fixed. We will make it rougher using brushes and a layer mask.
Create a Layer mask for the TOP-LESS layer. Load Photoshop’s default brushes set. Use the rough brushes in this set on the layer mask using black to reveal parts of the ORIGINAL layer below.
Once you have the bottom part of the building ready, turn off the visibility of the TOP-LESS layer to reveal the ORIGINAL layer. Get the Pen Tool (P) and trace the contour of the top part of the building using paths. When your done, convert the path into a selection, go to Edit>Copy and then create a new layer above the TOP-LESS layer and paste with the shortcut Ctrl+V. Name this layer BUILDING-TOP. Select the new created layer and rotate it about 5 degrees.
Now you will start destroying the building. This operation has to be done manually with the Lasso Tool (L). Select the BUILDING-TOP layer and select small size parts of the building. After making a selection right-click and choose Layer Via Cut because you must have these small pieces of debris on a separate layer in order to rotate them. Cut multiple pieces as you see on the image below. I grouped all the layers containing the small pieces of debris.
This building needs a more rougher look. Create layer mask for the BUILDING-TOP layer and use the same procedure as on step 4 to create some rough edges. Again, paint with black on the layer mask so that you hide parts of the building. Once I made the rough look using brushes on the layer mask I used a grunge concrete texture with Overlay Blend Mode to create more damage effect.
Download the Media Militia particles pack and open Media_Militia_Particles023.jpg. Scale it down if necessary and paste it over the building to add more debris. I put it in the same group as the other debris pieces made on step 6.
Now it’s time to make your meteorite. As I said, you can create it from scratch using only filters. I discovered this technique one day while messing around with filters. Here is how you do this.
Create a new layer above the other layers and name it METEORITE. Select the Lasso Tool (L) and draw by hand a roundish shape. Try to avoid straight lines cause rocks usually have no straight lines. When you have a selection that you like, make sure your background and foreground colors are set to Black and White and go to Filter>Render>Clouds and then Difference Clouds. Try Difference Clouds a few times. If you are not happy repeat the process from Render>Clouds. Try to get a mixed surface with black and gray.
When you’re satisfied with how the rock looks after applying the clouds, go to Filter>Sketch>Bas Relief. Set Detail to maximum, Smoothness to 2 or 3 and try the different light directions. I chose Right.
Now that you have the rock, you have to turn it into a meteorite. For that you must create a layer style so open the layer styles window by double clicking on the METEORITE layer.
Meteorite layer style
Keep in mind that this layer style might not look exactly the same on your meteorite because it depends on the amount of black and white areas you have on it. After applying the style try changing the Contrast of your meteorite using Levels to increase highlights and see how it looks. Also try different blend modes for different results.
Bevel and Emboss
You can also apply a Pattern Overlay with a rock texture and Overlay Blend Mode if your meteorite needs more texture.
After applying this layer effects you should get something similar to the image below.
Select the Smudge Tool and smudge one end of the rock in order to create a motion effect.
In order to create the smoke trail you will have to create a custom brush using the Brush Preset Editor. Get a soft brush slightly bigger than your meteorite and press F5 to open the brushes window or go to Window>Brushes. This is where you have to create your smoke brush.
First, go to Other Dynamics and increase opacity to about 40%.
Next, activate Texture and choose the Clouds pattern locate in the Pattern set (it comes with Photoshop). Check he Invert box next to the pattern thumbnail, increase scale to about 90% and play with the sliders until you get something you like. Also try enabling/disabling Texture Each Tip.
The Mode option depends on the background where you will use the brush, I used Multiply here but you can try the others. Just try to get the smoke to be fluffy and smooth. You will have to create two smoke trails. One lighter and one darker.
Use the same smoke brush you created and use a darker gray to create another smoke trail. This time you can increase the size of your brush a few pixels and try a different Mode. Create the black trail above the lighter smoke layer. On a new layer, stroke along the smoke trail using orange and set the Blend Mode to Overlay. That will be the light left behind by the meteorite.
Open the explosion stock image and scale it down as in the image below. Change the Blend Mode to Screen and use a Soft Eraser or a Layer Mask to hide unwanted edges.
Open Media_Militia_Particles013.jpg (ignore the text in the image) and erase the middle part because the concentration of particles is too big there. Only leave the outer ones. Place them on the exit and entry points of the meteorite.
Use the Marque Tool and create a selection the size of the damaged zone and add some black and white clouds. Set the Blend Mode to Hard Light and decrease Opacity to 45%. Duplicate the Layer and change the Blend Mode from hard light to Soft Light and increase Opacity to 75%.
The last thing I did was to add some lights. Use a light orange color and Blend Mode - Vivid Light. Change opacity if the effect is too strong.
The scene is ready but it can look much better making some general adjustments. I always include a post editing step on my creations because I always end up with a better result.
Select the entire canvas and go to Edit>Copy Merged. Create a new document and paste the image. Add a Gradient Map Adjustment Layer, set the layer Blend Mode to Overlay and decrease the Opacity to 30%.
You have to adjust the general exposure of the image and make it brighter. I usually use Levels but this time I decided to change. So add an Exposure Adjustment Layer and use the settings shown in the screenshot below.
I wanted to give the image a bit more of depth so I used some more particles from the Media Militia pack and added some blur to them. I also added a subtle vignette effect. You can add some motion blur to the meteorite and other parts of the image if you want.
The last step is a general light shift. The light source in this image is on the left side so I wanted to enhance that. As always, I used the Lighting Effects filter.
Select the top most layer on the palette and press Shift+Ctrl+Alt+E to create a stamp of all visible layers. That will create a new layer that you can edit without affecting the other layers. Go to Filter>Render>Lighting Effects and use the settings shown in the image below.
