In this tutorial we will create an aquatic scene about a fisherman 
catching a big shark. There will be some blood and some underwater 
seamless blending.The techniques used here are simple so let’s get 
started.
What you’ll be creating
You will create an aquatic scene. You will need Photoshop CS5 or newer in order to follow this tutorial.
 
Tutorial Resources
Step 1
Create a new document 900×600 px. Save this file and (optional) name 
it “Fisherman”. Open the “Sky” photo and make a copy of the whole image 
by pressing Ctrl + A. Make a copy by pressing Ctrl + C. Go back to the 
“Fisherman” file and paste the copied file by pressing Ctrl + V. Use 
Free Transform (you can free transform layers by pressing Ctrl + T) to 
place the sky as I did in the image below.
 
Step 2
Create a clipped curves adjustment layer (there are a lot of tutorial
 on clipping photoshop layers, it is suffice to say that in order to 
clip a layer to another you alt click between the two layers in the 
layer palette). Below are the settings I used in order to change the 
color of the sky (drag the blue curve up and the red curve down).
 
Step 3
Import the moon brushes. Create a new layer and create a new moon as I
 did. Group the layers together (Ctrl + G)(to keep the file tidy) and 
name it Sky.
 
Step 4
Open the image “Underwater”. Select all, copy and paste into the 
“Fisherman” scene just as we did in step 1. Resize it as shown in the 
image below (with free transform  Ctrl + T).
 
Step 5
Create a layer mask for the underwater layer (Layer -> Layer Mask 
-> Reveal All or you can click on the little icon in the layer 
palette). Select the Rectangular Marquee Tool and select the upper half.
 Make the foreground and background colors default ( shortcut D) and 
click the layer mask to make sure it is selected. Press Alt + Delete to 
fill the selection with black.
 
Step 6
Create a new layer and fill it with #79a272 color (a green color). 
Change the blending mode to overlay. Create a layer mask for this layer.
 Choose the Gradient Tool and while holding Shift drag from the upper 
portion of the image to the lower in order to create the effect shown 
below (remember, in the layer mask and not over the color layer).
 
Step 7
Import the Bubble brushes. Create a new layer and use the bubble brush as I did in the image below.
 
Step 8
Import the Fish brushes. Create a new layer and use one of the fish 
brushes to create a couple of small black fish in the underwater. Lower 
the opacity of the fish layer to 50%.
 
Step 9
Open the psd file “Fish”. Select a fish with the rectangular marquee 
tool. Copy and paste the fish into our working document. Convert the 
newly imported layer to a smart object (right click the layer and choose
 “Convert To Smart Object”). This will allow us to resize the layer 
without actual loss of pixel data. Place the fish near the left side of 
the underwater. Press Ctrl + D to duplicate the fish layer and move it 
next to the other fish.
 
Step 10
Import the light brushes. Create a new layer and change it�s 
blending mode to Overlay. Using one of the light brushes create a light 
as I did in the image below. Change the fill of the layer to 31%.
 
Step 11
Create a new layer and change the blending mode to Overlay. Use the 
light brush again to create a new light. Blur this light with a 20px 
Gaussian Blur (Filter > Blur > Gaussian Blur). Lower the fill to 
51%. Create a layer mask and mask the half upper portion of the light.
 
Step 12
Duplicate the light layer and drag it to the left.
 
Step 13
Create a new curves adjustment layer. Drag the curve down in order to
 darken the scene. Fill the layer mask with black. With a white brush 
paint on the bottom of the scene in the layer mask to reveal the 
darkening effect.
 
Step 14
Create a hue/saturation adjustment layer. Below are the settings I 
used. Fill the layer mask with black and paint with white on the bottom 
of the scene (like I did on step 13). The reason we do this is because 
usually underwater should be darker and more desaturated than the rest 
of the scene.
 
 
Step 15
Open the image “Sea”. Copy all and paste into the working document.
 
Step 16
Create a layer mask for the sea layer. With a black brush paint in 
the layer mask until you have something resembling my result below.
 
Step 17
Create a Curves Adjustment layer and clip it to the sea layer. Drag the curve up to lighten the waves.
 
Step 18
Create another clipped Curves Adjustment layer. Drag the red curve down to make the waves bluer.
  
 
 
Step 19
Create a new layer and clip it to the sea layer. Change the blend 
mode to overlay. With a 20% opacity white brush paint in the areas shown
 below.
 
Step 20
Create a new layer and change the blending mode to Color Dodge. With a
 soft brush at 5% opacity paint with #008c29 color over the sea.
 
Step 21
Open the image “Little Shark”. Select all, copy and paste into our 
working document. Convert the little shark layer into a smart object and
 lower the opacity to 45%. Place the little shark as shown below.
 
Step 22
Open the image “Big Shark”. Select all, copy and paste into our 
document. Convert to smart object. Resize and place the big shark as I 
did in the image below.
 
Step 23
Add a layer mask to the big shark layer. With a black brush at 30% 
Opacity paint with black the lower areas of the shark so that it appears
 it is submerged into water.
 
Step 24
Create a new layer and change the blending mode to Overlay. Clip it 
to the shark layer. With a white brush at 20% Opacity paint over the 
nose and the tail of the shark to make them stand out.
 
Step 25
Create a clipped hue/saturation adjustment layer. Increase the 
saturation to 57 and fill the layer mask with black. With a white brush 
at 100% Opacity paint in the layer mask over the mouth of the shark to 
make it red and bloody.
 
Step 26
Create a new layer and clip it to the shark layer. Change the 
blending mode to Color Dodge. With a 1px white brush at 60% Opacity 
paint some lines on the portion of the shark that is above the water. 
This will make the shark stand out more.
 
Step 27
Create a new layer and clip it to the shark layer. Change the 
blending mode to Overlay. With a 3px brush at 50% opacity paint over the
 indicated areas.
 
Step 28
Create a clipped Curves Adjustment layer. Drag the curve down to 
darken. Fill the layer mask with black. With a white brush paint over 
the indicated areas in the layer mask.
 
Step 29
Create a clipped Hue/Saturation Adjustment layer. Drag the saturation
 slider all the way to -100. Fill the layer mask with black and with a 
white brush paint in the layer mask only inside the mouth to keep the 
redness.
 
 
Step 30
Create a new layer. Choose a chalk brush. With a white color draw 
some little waves crashing into the body of the shark like I did in the 
image below.
 
Step 31
On a new layer create some bubbles in the underwater portion of the shark.
 
Step 32
On a new layer with a yellowish color draw something like a hook in the mouth of the shark.
 
Step 33
Import the blood brush. Create a new layer and with a red color 
create a red splash near the mouth of the shark. You don�t have to use
 the same brush I use or the same splash, most blood splashes out there 
will do. Use a layer mask to hide unwanted parts of the red splash.
 
Step 34
Create a new layer and clip it to the splash layer. With a soft white brush draw some highlights on the splash.
 
Step 35
On a new layer create another red splash using the blood splatter brush. Group the blood layers together.
 
Step 36
On a new layer create some blood marks on the side of the shark using either the blood brush or the standard chalk brush.
 
Step 37
Make another layer and draw some blood hanging from a tooth of the 
shark. Make another clipped layer to the hanging blood layer and create 
some shadows and highlights to make the blood look more real.
 
Step 38
On a new layer create some blood flying from the mouth of the shark using the blood brush.
 
Step 39
Add some shading (highlights and shadows) to the blood layer you just
 created. I used a couple of layers to draw with white and black and a 
curves layer, all clipped to the blood layer.
 
Step 40
On a new layer cover with red the surface of the shark�s eye. Use a dark red.
 
Step 41
Now on another layer create with a brighter red the iris.
 
Step 42
At this step I feel that I can add more wounds to make the scene more
 realistic. Create a new layer and with the blood brush or the standard 
chalk brush create some red marks on the sharks nose. Double click the 
layer to enter blending mode and use the settings shown below.
 
Step 43
On a new layer draw by hand with a black and white brush some more shading for the wounds on the nose.
 
Step 44
Now let�s make some underwater wounds. On a new layer create some 
wounds near the tail of the shark with a dark red. Lower the opacity of 
the layer to 64%.
 
 
Step 45
With a round soft brush at 10% Opacity draw some red blood dispersing
 in the water near the wounds. Group all the layers associated with the 
shark and name the group “Shark” to keep the document tidy.
 
Step 46
Open the image “Boat”. Copy and paste the boat into our working 
document. Convert the boat to a smart object. Resize the boat as shown 
below.
 
Step 47
Add a layer mask to the boat layer. Mask away the bottom of the boat so that it looks submerged in the water.
 
Step 48
Create a clipped Hue/Saturation Adjustment layer. Drag the saturation slider to -66.
 
Step 49
Create a clipped Curves Adjustment layer. Drag the curve down to 
darken. In the layer mask use a soft white brush at 50% opacity and 
2-3px size to create some lines along the lines of the boat.
 
Step 50
Create a new layer and clip it to the boat layer. Sample a blue color
 from the water and with a soft brush at 2-3 px create some blue lines 
along the boat. This step is just to have some color variation in the 
boat.
 
Step 51
Create new layer and clip it to the boat. With the chalk brush draw some blood spots on the boat surface.
 
Step 52
Create a new layer. With the chalk brush at 40-50% Opacity draw some small waves splashing into the boat.
 
Step 53
Open the file “Fisherman”. Make a selection of the fisherman (with 
the pen tool). Copy and paste the fisherman into our working document. 
Convert it to a smart object. If needed create a layer mask to hide 
additional parts of the fisherman.
 
Step 54
Create a clipped Curves adjustment layer. Drag the curve down to darken the fisherman until he is just a silhouette.
 
Step 55
Create a new layer and clip it to the fisherman. Sample a light blue 
color from the sky or sea and paint some light on the left side of the 
fisherman as shown below. No need for great precision, just the general 
feeling of light hitting the left side of the fisherman.
 
Step 56
You may notice that the fishing line is not complete. Create a new 
layer and with a black chalk brush at 1px size complete the line to the 
shark�s mouth.
 
Step 57
The fisherman while fighting the beast should have some blood on 
himself. Create a new layer and with the chalk brush draw a couple of 
red spots on the fisherman. Group all the layers related to the 
fisherman and name the group “Fisherman”.
 
Step 58
Time to add some splashes. Open the file “Splash1″. Choose Select 
> Color Range. Click once on a white spot on the image to make a 
selection of the drops and click ok.
 
Step 59
Now that we have a selection of the splash press Ctrl + J to make a 
new layer from the selection. Ctrl + A to select all, Ctrl + C to copy 
and while back in our working document Ctrl + V to paste the water 
drops.
 
Step 60
Add a layer mask and mask all the unwanted parts until you have something like the image below.
 
Step 61
Repeat the steps 59-60 two more times to add splashes in the indicated regions but this time using “Splash2″ image.
 
Step 62
Import the splash brush. Create as many layers as you see fit and 
create splashes on them using the brush. You can mask portions of the 
splash you don�t like. Place some splashes around the shark and some 
around the boat. Group all the splashes together and further add a layer
 mask to the group to refine where the splashes are.
 
Step 63
Create a Color Balance adjustment layer. Use the settings shown below in order to achieve a darker, more interesting mood.
 
Step 64
Create a new layer and set the blending mode to Overlay. With a soft 
brush paint with white over the areas indicated below in order to 
emphasize them.
 
Step 65
Create a Curves adjustment layer. Drag the curve down to darken. 
Select the gradient tool and in the layer mask drag from the up left 
corner towards the right bottom corner with black and white as default 
colors in order to reveal the darkening effect only in the upper left 
portion of the scene.
