Part 2 of our amazing home aquarium tutorial!
Open a desert-like image and flip it Horizontally. Hit Ctrl/Cmd_L to open the Curves dialog and adjust it to 51, 0.70, 225. Using the Free Transform tool, adjust the edges. Again try to follow the floor perspective to move the layer correctly and change the blend mode to Multiply.
Open the image of your subject in Photoshop. Using the Magic Wand tool, change the Tolerance to 20 and tick Contiguous. Hold the Shift key and start deleting the background. When you are done, invert it using Shift+Ctrl/Cmd+I, cut out the woman and copy and paste on the background using Transform (Ctrl/Cmd+T) to scale her.
On a new layer open the Brush palette and select a small soft brush. Holding Alt/Opt, get some colour samples from the hair and paint some extra hair and woman layers, open a Hue/Saturation dialog and lower Saturation to -45. Apply a Gaussian blur with a Radius of 1px.
Hold Ctrl/Cmd and click on the woman thumbnail to select the layer then add a layer mask. Now select the mask thumbnail and repeat the actions from step 8. Go to Filter>Blur>Gaussian Blur and try a Radius of 10px to get a nice soft edge around the woman then click OK.
Select the woman’s layer and open the Colour Balance adjustment, click on the Preserve and change the Colour Levels to -24, 0 and 02. Create another layer above and fill the selection with #29a5aa, changing to Overlay with Opacity at 70%. Merge all the woman’s layer by Ctrl/right-clicking and choosing Merge Layers. This will come in handy if you want to move, rescale or transform the woman separately layer on.
You can use a default brush to create small bubbles, just click F5 to open the Brush palette, click and change the values on the Shape Dynamics, Scattering and the Other Dynamics to Pen Pressure. Start drawing the bubbles, varying the brush size and lowering the layer opacity.
Create another layer and fill with grey using the Paint Bucket tool. Go to Filter>Render>Lighting Effects, choose Light type: Spotlight, turn the light source to the right and apply. Create another layer and fill with #074e54, changing the blend mode to Soft Light. Those final two effects have added some depth to your image.
