Now with the same brush, but at a new layer draw a small haze on ships. Select colors, used Eyedropper Tool (I) from places near the ships to accurately observe the gamut. Do not paint over the ships fully or you’ll lose the realism. Make this layer as Clipping Mask (Cmd/Ctrl + Opt/Alt + G).
It remains to add the haze on the aliens. But first, let me do a brush like smoke. I modified the standard “Per Smoke Brightness Variance” Photoshop brush. Select brush “Per Smoke Brightness Variance” and press F5 to move in Brush settings. Increase the size to 500px, set Spacing to 80% and go to “Shape Dynamics”. There do brush of different sizes (Size Jitter: 100%) and add it to the rotation (Angle Jitter: 40%). It remains to give a little volume to brush, because when use in drawing it was not linear. On tab “Scattering” set Scatter: 75% and Count: 1. Save this brush because it will need us at the end of this tutorial.
Create a new layer, set color #a09081 and brush Opacity: 40%, use created brush to draw fog on the alien’s legs and a little around. With the weather or situational effects can be achieved by masking the unpleasant parts or hiding unwanted elements. With skillful use of surrounding opportunities as possible to achieve realism, but only when you know the limit :).
The resulting color of smoke seemed to me too bright and I added an adjustment layer “Hue/Saturation” to the fog combined with the colors of image. In “Hue/Saturation” set Hue: -9, Saturation: +11, Lightness: -11 and applied this layer to fog layer.
Here is my result. Layers with aliens, I also combined into one group “Aliens” (Cmd/Ctrl + G). Next all following layers should be higher than the two groups with the scenery and aliens.
Proceed to part with addition of fire and pieces of dead aliens. I decided to add these pieces to convey a sense of the battle. As with the aliens, and their parts move them to a working document (Step 17). Place the parts in the right places. In resource image only two pieces, but experiment with the rotation – connection of both and you will get more (use Transform Tool (Cmd/Ctrl + T)). In this way I made the third part. When you are satisfied with the arrangement of the parts, merge all layers with pieces in one layer (Cmd/Ctrl + E).
To create a shadow under these parts I used style “Drop Shadow” (Layer > Layer Style > Drop Shadow… or icon on Layer panel). Set Opacity: 100%, Angle: 151 degrees and set checkbox on “Use Global Light”, Distance: 33px, Spread: 0%, Size: 100px. When you are finished, press OK.
Color of aliens items are not combined with the general atmosphere, so I will change this by using adjustment layers. The first layer is “Brightness/Contrast”. Set Brightness: -92, Contrast: 46. So I darkened the parts to prepare them for the imposition of the desired shade.
Now color. Next adjustment layer is “Color Balance”. Set for Midtones: Cyan-Red: +16, Magenta-Green: -16, Yellow-Blue: -26; for Shadows: Cyan-Red: +6, Magenta-Green: +9, Yellow-Blue: -10. Since in the original form of these cases were much brighter, then tab “Highlights” a don’t use. Now all the parts are harmoniously combined with the color gamut.
One last adjustment layer is “Hue/Saturation”. Set Hue: -35, Saturation: -36, Lightness: -31. Now a bit of balancing the color and saturation for realism. I specifically decided to write you this color scheme if you want to add other objects and implement them in this atmosphere.
