How to Create a Cerberus Photo Manipulation in Adobe Photoshop
Cerberus is a three-headed dog from Greek mythology, the guard of the gates of Underworld. While he’s usually pictured as a furious, blood-thirsty beast, I like to think of him as a good dog just doing his duty. Today I’ll show you how to create Cerberus using the techniques of photo manipulation in Adobe Photoshop.
What You Will Need
You’ll need the following resources in order to complete this project:
1. How to Prepare the Assets for the Photo Manipulation
Open of the rottweiler photos in Photoshop. Take the Magic Wand Tool (W) and select the area outside its body.
The automatic selection is rarely perfect, so let’s fix it. Go into the Quick Mask Mode (Q) and use a brush to paint the unselected areas.
Go out of the Quick Mask Mode (Q) and go to Select > Inverse to invert the selection. Then grab the Magic Wand Tool (W) again and select Refine Edge on the top.
Change the View Mode to On Black to better see the edges.
Check Smart Radius and increase the Radius. Then play with the other settings until you’re satisfied with the result.
You can also use the Refine Radius Tool (E) to make the edge detection more accurate, especially where the fur is visible.
When you’re done, press OK and invert the selectionagain to remove the background, or simply copy the selection to another file.
Do the same to the other dogs. Use the Quick Mask to remove the parts from the neck down.
Gather all the dogs in one file.
The main dog is illuminated in a different way than the others, so let’s fix it quickly. Select its layer and go to Image > Auto Contrast, then Image > Auto Tone.
2. How to Merge Various Photos Into One
Use the Lasso Tool (L) to select half of the front of the main dog. We need to make the chest wider to place all these extra heads.
Use the Move Tool (V) to drag the selected half to the right, creating some space in between.
This space must be filled. Select it with the Lasso Tool (L).
Go to Edit > Fill and select Content-Aware.
The chest should get filled nicely!
Let’s make the body more muscular and intimidating. Go to Filter > Liquify and use the Forward Warp Tool (W) to “sculpt” the body. Use a small brush and be very careful—you can use Undo only once here, and it’s hard to fix a modification. To be safe, press OK after each successful modification and go back to this filter to continue.
After the body is done, remove the head with the Lasso Tool (L) (no animals were harmed in the production of this tutorial!).
I decided to flip the whole image with Image > Image Rotation > Flip Canvas Horizontal. This isn’t necessary; it just looked better to me.
Time to add the heads of the dogs. Drag one of them over the main body and use the Free Transform Tool (Control-T) to adjust the size of the head to the body.
Use the Eraser Tool (E) or the Layer Mask with a soft brush to subtly blend the overlapping parts. You can learn about the power of the Layer Mask from the quick tutorial below:
… and then use the Liquify filter to reshape its neck. You can show the Backdrop of the body to see the changes better.
Then use the Layer Mask again and continue with the last head.
3. How to Add and Adjust the Background of the Photo Manipulation
Let’s add the background now. Drag the photo to the file and adjust its size with the Free Transform Tool (Control-T). Make sure the ground fits the perspective of the dog’s body. Then use the Crop Tool (C) to crop the whole scene.
Open Window > Adjustments and select Hue/Saturation from the panel (with the background layer selected).
Play with the sliders to make the background dark and mysterious.
Add another Hue/Saturation adjustment, and this time make everything hot orange.
Use the Paint Bucket Tool (G) to fill the Mask of the adjustment layer with black. Then paint on it with white to “paint” the light coming from the lower right corner.
This bright light has flattened the ground, so let’s adjust it. Right-click the adjustment layer and select Blending Options. Hold Alt and drag the lower black marker to the right. This will remove the effect of the adjustment over the darker areas of the background.
To make the light brighter, change the Blend Mode to Linear Dodge.
Duplicate (Control-J) the adjustment to make the effect stronger. Then modify it to better fit the environment.
Add a Brightness/Contrast adjustment.
Use it to make the whole scene darker.
Use the Layer Mask to remove the darkness from the foreground and keep it in the background.
4. How to Make the Scene Consistent
Let’s go back to the dog now. Select its layers and group them (Control-G). Then add the Hue/Saturation adjustment to the group. Don’t forget to clip it (Control-Alt-G) to exclude the background.
Use the adjustment to fit the lighting on the dog to the background without any lights.
“Turn on” the lights again, and paint on the Layer Mask of the darkening layer to reveal the light on the dog’s coat.
Add another clipped Hue/Saturation layer. This time make the fur bright, as if illuminated by the orange light source.
Use the Layer Mask again to affect the illuminated side only.
Go to the Blending Options and drag the lower black marker to remove the light from the darker parts.
Duplicate (Control-J) the adjustment layer and make it affect an even smaller area…
… but make it stronger with Color Dodge Blend Mode.
Let’s make the eyes glow! Add another Hue/Saturation layer and make it red and saturated.
Use a Layer Mask to apply it to the eyes only.
Change its Blend Mode to Linear Dodge to make it better fit the details of the eyes.
Duplicate the layer and use this stronger effect in the darker parts of the eyes. If you want to learn how to animate glowing eyes, check out this tutorial:
5. How to Add the Final Touches to the Photo Manipulation
A nice trick to make the new elements a part of the background is to blend some of their parts with it. Add a Layer Mask to the group of dog photos and gently paint over some shadowed areas that still stand out too much (especially on the backs of the heads).
The whole dog is also very sharp, and thus still quite flat. Go to Filter > Convert for Smart Filters and then Filter > Blur > Gaussian Blur. Make the dogs blurry, but not too much.
Smart Filters have a Layer Mask, too! Use it to leave the blur only on the edges.
Let’s add a glow to the sky. Select it with the Magic Wand Tool (W)…
… create a New Layer and paint the colors…
… and then use a Layer Mask to clean the effect off the arches.
Finally, you can add some adjustments to the whole scene. Levels will help you adjust the contrast, and Vibrance will make the colors more vivid.
When you’re done, right-click the layers and select Flatten Image. Go to Filter > Noise > Add Noise to unify the whole scene with a slight grain. Finally, go to Image > Size and make the image smaller before you publish it.
