What we'll be doing today
Step 1
Let's start by creating a new document. Set the dimensions of the canvas to 2400x3600px.
Step 2 (Add Sky)
Open and drag the Sky 1 into canvas and keep it at the top part of the canvas.
Open and drag the Sky 2 into canvas and Change the mode of the layer to Hard Light and reduce its Opacity to 80% Then slightly erase the bottom part with Eraser Tool (E )
Step 3 (Creating Sea part)
Open and drag the Sea 1 into canvas and erase the sky part as shown in the image.
Duplicate the layer, move it to touch the sky and blend both those images using Eraser tool (E)
Step 4 (Build huge wave)
Open and drag the Sea 2 into canvas and erase the remaining part of image except the wave part we need
Use Color balance (Ctrl+B) with values (-50, 0 ,+10) to mix it with Sea.
Step 5 (Create Thunder)
Take a new layer on top of all and use Brush Anodyne Stock Light No. 948 with white color to bring Thunder effect.
Take a new layer and use Soft round Bush Tool (B) to make the thunder glow and change the layer mode into Overlay.
Step 6 (Catch the shark)
Open and drag the Shark image into canvas and erase surrounding parts of the shark.
Take a new layer and use Soft round brush tool (B) with color (#354254) to paint glowing part of Shark on left hand side (As the thunder light is coming from other direction i.e Right)
Use Color balance (Ctrl+B) with values (-50, 0 ,+55) to change the color of Shark from Yellow shade to sea blue.
Copy the wave part and paste it again on right side of shark mouth.
Step 7 (Add boat)
Open and drag the boat image and select the red boat using Pen Tool (P) and place it in front of shark.
Step 8 (Bring Jumping Couple in)
Open and drag the Jumping couple image into canvas and select them using Pen Tool (P).
Step 9 (Adding splashes)
Now let's play with adding splashes around the shark, boat and characters. For that create a new layer and add water splashes with the downloaded brush Splashes to make contact between characters and water.
Step 10 (Adjusting the light)
Now let's change the environment lighting a bit bright using Curves option. For that go to layer > New Adjustment Layer > Curves then click OK.
And make curve as I shown below and apply it to total canvas.
Here is how it looks.
Step 11 (Adding Title and Captions)
Let's start adding Titles. Create a new layer, type the JAWS and make values as shown below.
Lets arrange the words (JWS) in such a way to have Shark instead of "A" in JAWS.
Make the title glow, double-click on the JAWS Title layer to access the "Layer Style" and use the value as shown below.
Then add captions as shown in the image. Feel free to choose fonts and colors of your own choice.
Then create a new layer and add some splashes on the title as well.
Step 12 (Add Dark shade at the bottom)
Let's add the dark shade at the bottom part of the poster. For that with soft round Brush Tool(B ) paint black color and change the mode of the layer into Multiply.
Step 13 (Adding subtitles)
We are almost done! Let's add subtitles at the bottom of the poster. Create a new layer and make rectangular shape with Rectangular Marquee Tool(M ) and fill it with dark blue color(# 00020a).
Let's give credits to crew.
That's it, we are done! And here is the Final poster.
