Tutorial continued… Reduce planet earth down to the size of an egg yolk using Photoshop’s adjustments and layer styles
With the Background layer in the palette highlighted, click once with the Magic Wand tool on the white background around the egg white. This starts off the selection process.
Continue to Shift-click over the white background to further select the entire area. Avoid selecting the eggshells, yolk, or egg white at this stage. If you need to undo any of the selection, hold Opt/Alt and click. When completed, go to Select>Inverse to flip the selection.
Press Q to enter Quick Mask mode. Use a hard-edged brush to paint over both the eggshells. Paint as close as you can to where the shells meet with the egg white, leaving a slight gap. Press Q to exit Quick Mask mode.
Add a new Hue/Saturation adjustment layer from the Layer menu. The active selection will attach itself to the adjustment’s mask. Select the Pen tool and make a path around the base of one of the eggs. Start from where the egg white meets the edge of the shell and work your way around the base.
When you reach the other side of the eggshell, stop at the point where the shell meets the egg white. Close the path by drawing across to the first point made and Cmd/Ctrl+Ctrl/right-click and choose Make Selection. With black as your Foreground colour, Opt/Alt+Backspace to add this selection to the adjustment’s mask.
Opt/Alt-click on the mask to view it in the black and white preview mode. You may see some areas, where the eggshell meets the egg white, that are not in black. Use the Brush tool to touch these areas up, adding them to the mask.
Repeat this process of selecting and adding to the mask for the other egg. The last object to add to the mask is the yolk. Cmd/Ctrl-click on the mask of the earth’s layer, and then Opt/Alt+Backspace to apply this to the mask of the Hue/Saturation adjustment layer. You should end up with just the egg white masked on the adjustment.
The Hue slider in the Hue/Saturation adjustment can be moved to change the colour of the egg white. Tick the Colorize box and set Hue to 220, Saturation to +30. Change the blend mode of the adjustment layer to Color.
To soften the edges between where the eggshells touch the egg white, select the Blur tool. Lower its Strength down to 60% and zoom in to get a closer look. Make sure the Hue/Saturation adjustment’s mask is selected and brush over the edges to soften them.
Select the Magnetic Lasso tool and set its Width to 4px, Contrast 25% and Frequency 94. Zoom into the inside edge of the cracked egg and draw a path around where there is egg white inside. When using the tool, hold Opt/Alt to activate the Polygonal Lasso tool to draw straight lines back to the first point of the path.
Click on the Hue/Saturation adjustment’s mask and select the Eraser tool (with Foreground set to black). Erase the areas where there is egg white inside the shells. The selection will let you get close to the broken edge of the egg to reveal the blue hue.
Use the Blur tool to remove the harsh edge from where the egg white meets the broken edge of the shell. Use the Magnetic Lasso tool on the other half of the egg and erase where there’s a small amount of egg white left over.
Duplicate the Background layer and go to Filter>Sharpen>Unsharp Mask. Set Amount to 100% and Radius to 2.5px. Apply a layer mask to the duplicate and press Cmd/Ctrl+I to turn it from white to black. Use the Eraser tool over the front of the shell on the right to bring through the sharpening filter.
