Mastering Photoshop Techniques: Layer Styles


Layer Styles are nothing new. They’ve been used and abused again and
again. Despite their ubiquity, or perhaps because of it, many designers
do not yet realize the full potential of this handy menu. Its beauty
lies in our ability to create an effect and then copy, modify, export,
hide or trash it, without degrading the content of the layer.

Below we present, step by step, several practical techniques to help
you refine your designs, increase productivity and reduce layer clutter.
You will find more useful Photoshop techniques and tutorials in our
hand-picked selection, Best of Photoshop on Smashing Magazine.

The Bump Map Effect


“Wait, what?” you exclaim, “There’s no bump map effect in the Layer
Styles menu!” That’s true, but by combining Pattern Overlay and Bevel
and Emboss, we can achieve a textured, bump-mapped surface with a
controllable light source.

This technique requires two images: one for texture and color, and
the other to serve as a depth map. The depth map needn’t have any hue
because it determines depth based on a composite value, black being the
lowest, white the highest. In some cases, you may be able to use the
same image for both, but in our example we’ll use completely different
ones.

Step by Step



  1. We’ll start by creating our bump map pattern. Open the diamond-plate.psd file.
  2. Inside you’ll find a number of white shapes on a black background. Create a pattern from this document: Select All (Cmd/Ctrl + A), then “Edit” → “Define Pattern.” Name it “diamond plate bump map” and click okay.

    Creating the diamond plate pattern.
  3. Now, open the start.psd file.
  4. Repeat step 2 to create a pattern from the “patchy gray” layer. This will be used later to add texture to our background.

    Defining the texture pattern.
  5. After creating the pattern, delete the “patchy gray” layer. It’s no longer needed.
  6. Use the Rectangular Shape tool to create a shape layer about 20
    pixels wider and 20 pixels higher than the canvas. Change the color of
    this layer to a dark, brownish, chromatic gray.

    Creating the shape layer for our background.
  7. Be sure that the shape layer doesn’t have any Layer Styles already
    applied to it (Photoshop will often apply the most recent Layer Style
    automatically). Then, begin the new Layer Style by adding a Pattern Overlay.

    Adding a Pattern Overlay effect.
  8. Choose the “patchy gray” pattern from the pattern picker, and change the Blend Mode to Soft Light. This will add the texture to our background layer.


    Adding a pattern overlay effect.
  9. Next, add a Bevel and Emboss, along with the Texture effect.
    This time, change the Texture effect’s Pattern to the “diamond plate
    bump map” pattern created in step 2. We now have a grungy diamond plate
    background.


    Applying the Bevel and Emboss texture effect.
  10. As with most Layer Style effects, the default values are rarely ideal. By tweaking the Bevel Type and Size, Gloss Contour, Highlights, Shadows and Light settings you can achieve some dramatic results.


    Tweaking the Bevel and Emboss settings.
  11. With a few extra effects, you can shape the background layer even more. The example has a Gradient Overlay to simulate reflected light by darkening certain regions of the image.


    Using the Gradient Overlay to darken some regions.
  12. You may notice that the highlights from the Bevel and Emboss filter
    all seem to have the same value. This is because the Bevel and Emboss
    effects are very high on the Layer Style’s stacking order. To darken the
    highlights that lie outside our main light source, simply paint a Layer Mask using the Brush tool.

    Painting a mask to increase the appearance of light in the background.

We now have a textured, bump-mapped background that is completely
dynamic; everything about it can be modified easily from within the
Layer Styles menu. Consolidating complex imagery into one dynamic layer
like this can reduce layer clutter dramatically and allows you (and
whoever else may be using the file) to easily find and modify things.
Now, let’s move on to creating our icon.

3-D Modeling


By combining some interior effects, we can use the Layer Styles menu
to create simulated 3-D objects: great for icons, buttons and other
interface objects. We’ll now model the base of the round icon in the
example image using a single layer.

Step by Step



  1. Begin by creating a circular shape layer with a rich red fill.

    Creating the shape layer for the icon’s base.
  2. As is often the case when modeling a 3-D shape, let’s begin by adding a Gradient Overlay to our Layer Style.
    A white-to-black Radial-styled gradient set to Linear Burn works best
    for our implementation. Be sure the white area of the gradient is at the
    origin.

    Adding Gradient Overlay set to Linear Burn.
  3. We now have a dramatically shaded sphere with a head-on light source. By decreasing the opacity of the gradient, we can flatten the shape to a more concave button.

    Reducing the Opacity for a subtler effect.
  4. Let’s also move the direction of the light to the upper-left. While
    leaving the Layer Style menu open, move the mouse over the image itself
    (the Move Tool icon should appear). Simply click and drag the epicenter of the gradient to the upper-left of the shape layer.

    Repositioning the gradient within the Layer Styles menu.
  5. While Bevel and Emboss may seem like more logical tools, you can
    often get a cleaner, more customizable beveled look by using a
    combination of other effects. First, add a black Inner Glow, set to Multiply. Adjust the Choke, Size, Opacity and Contour until you have a softened edge inside the shape.


    Adding a Glow to darken the edge of the base.
  6. Like for any well-rendered spherical surface, we have to add some
    reflected light in our shadow region. This is easily achieved with the Inner Shadow effect.
    Change the color to white and the Blend Mode to Linear Dodge. Adjust
    the angle so that it appears in the lower-right of our shape. Tweak the
    Contour, Distance, Size and Opacity to create a subtler effect.


    Adding subtle reflected light using Inner Shadow.
  7. To enhance the feeling that the shape is part of the document’s
    “environment,” we can add some effects to interact with the background. Drop Shadow is usually the easiest tool to use for this. Massage the settings until everything feels right.


    A simple Drop Shadow goes a long way.

  1. Using the Outer Glow effect, we can
    simulate the reflected red light that our background image would absorb
    if this were an actual setting. Change the glow’s color to a darker red,
    and change the Blend Mode to darken. Again, work with the Size and
    Opacity settings to create the desired effect. This is one of those
    effects that, when used correctly, no one should notice because it just
    looks natural.

Please notice that Layer Style gradients can’t be dithered, which can
make them lower quality than their Gradient Layer and Gradient Tool
counterparts (— Marc Edwards).

Diffuse vs. Specular Light


Now, our icon reflects a simulated diffuse light, which gives it the look of a matte-finished surface. If you prefer a glossier appearance, you can easily create a specular highlight using (what else?) Layer Styles.

Step by Step



  1. Duplicate the current shape layer (Cmd/Ctrl + J).
  2. Clear the new layer’s Layer Styles: right-click the layer in the Layers palette and select “Clear Layer Style.”
  3. We also need to modify the shape of the layer to give the reflected
    light a sharper edge. Using the Direct Selection Tool (A), select the
    shape path in the layer’s vector mask. Copy it (Cmd/Ctrl + C) and paste it (Cmd/Ctrl + V) above the current path. Change this path’s mode to Subtract from shape area (-).
    Then move the shape down and to the right to create a crescent shape.
    You may also want to make the negative shape larger to create a more
    natural inside curve: simply Free Transform (Cmd/Ctrl + T) and then scale the shape up.

    Modifying the shape of the specular highlight.
  4. Because we need this layer only for its Layer Styles, we can set its Fill Opacity to 0%.

    Dropping the layer’s fill to 0%.
  5. We also want this layer to inherit the Layer Styles of the underlying layer, so create a Clipping Mask on the new layer (Cmd/Ctrl + Option + G).

    Creating a Clipping Mask to inherit effects.
  6. Now, begin the Layer Style with a Gradient Overlay.
    Use the default black-to-white gradient, and set the Blend Mode to
    Screen. Knock the Opacity down to about 50%, and change the angle to
    about 115°. You may need to change the positioning of the gradient,
    which you can do by clicking and dragging inside the document window,
    just as you did in the 3-D modeling section.


    Setting the Gradient Overlay to Screen.
  7. This is a good start for the highlight, but it still looks somewhat
    unnatural. Using a transparent inside stroke, we can shrink the
    perimeter of the interior effects. Add a Stroke effect to the layer and drop its opacity to 0%.
    Change the position to Inside, and work with the size slider until the
    highlight begins about where the darker inner glow ends on the
    underlying layer (the example image uses 5 pixels).


    Using a 0% Inside Stroke to shrink the perimeter of interior effects.
  8. To add a more dynamic look to your highlight, you can add a white Inner Shadow set to Screen with a custom contour. Tweak the distance and size settings to finish off the effect.


    The Inner Shadow creates a more dynamic specular reflection.

X-Ray Vision


Step by Step


To create the die-cut type inside our icon, we could turn the text
layer into a shape layer and use the paths to mask away areas from the
base. However, this would result in degenerated content; we would no
longer be able to modify the type. Instead, we’ll simulate a mask using
the Knockout Blending Option. This will also allow us to apply custom effects to the cut-out area.


  1. Create a new Type Layer with the text “fx”, and position it within the circular base. The example uses 120 point Garamond Bold Italic.
  2. Drop the Fill Opacity to 100%.
  3. Begin your Layer Style by adding an Inner Shadow. Increase the size, and increase the opacity to about 90%. You may also want to modify the distance and contour to your liking.

    The beginnings of the die-cut effect.
  4. We now have the beginnings of a die-cut effect, except that the text still shows the base below it. To fix this, go to the Blending Options section in the Layer Styles menu. Change the Knockout from None to Shallow
    (this setting samples pixels from the layer directly beneath the
    current layer’s group). Because our text layer doesn’t belong to a layer
    group, it samples instead from the Background layer. (Using a Deep
    Knockout would always sample from the Background layer, regardless of
    the layer’s group.)


    Shallow Knockout samples pixels from the layer directly beneath the current layer’s group.
  5. To get the text layer to sample from our diamond plate layer, start
    by clicking “Okay” to close the Layer Style menu. Select the text layer
    and both of the buttons that make up the base, and group the layers (Cmd/Ctrl + G).
    As you can see, the “fx” shapes are now drawing pixels from the textured layer directly below the new layer group.

    Grouping the icon so that the Knockout samples from the diamond plate layer.
  6. The knockout effect is very convincing, but the type still feels
    detached from the base. Let’s add a beveled effect to simulate the
    surface quality of the base. Start by adding an outside Stroke with a size of 2; then drop the opacity to 0%. This doesn’t achieve anything but is necessary for the next step.
  7. Now add a Bevel and Emboss effect. Change the Style to Stroke Emboss and Technique to Chisel Hard.
    This will apply the bevel’s lighting effects within the stroke area
    created in the step above. Modify the settings to achieve a subtle and
    smooth edge.


    Adding a Stroke Emboss.
  8. Let’s take the bevel one step further by adding a thin specular highlight to the bottom-right edges of the shape. We can use a white Drop Shadow effect, set to Screen, to add a bright highlight just at the edge of the bevel. You’ll want to modify the distance and size to give the highlight a sharp edge.


    Adding a thin specular highlight using a Drop Shadow.
  9. Finish off the Layer Style with more shading within the die-cut letters by adding a simple black-to-white Gradient Overlay, set to Multiply.

Quick Tips


Despite frequent misuse, the Layer Styles menu really is a powerful
tool that every designer should learn to work with. Not only does it
provide a level of speed and control not easily found through other
means, but it provides invaluable flexibility. Our example shows how a
multi-dimensional icon and a completely dynamic background can be
consolidated within four simple Shape layers, allowing them to be easily
modified, reused and repurposed throughout your designs. Below are a
few extra tips to remember when working on your next project.

Effects Stacking Order


You may have noticed sometimes that an effect isn’t visible when
another effect is being used. For example, a Color Overlay seems to
override a Gradient Overlay. This is because of the Layer Styles
Stacking Order. Just as with the Layer’s Palette, one layer will cover
another that is lower down in the stacking order. Unfortunately, the
Layer Styles menu doesn’t allow you to rearrange the order of effects.
One way around this (even if you sacrifice the ability to edit) is to
use Create Layers, which turns all of your Layer Style effects into
actual layers that you can move.

Interior Effects Stacking Order:


  • Stroke
  • Bevel and Emboss
  • Inner Shadow
  • Innger Glow
  • Satin
  • Color Overlay
  • Gradient Overlay
  • Pattern Overlay

Exterior Effects Stacking Order:


  • Stroke
  • Outer Glow
  • Drop Shadow

Non-Color-Specific Styles


Though not always possible, you may want to use black, white and
grays for your effects. Using monochromatic colors in conjunction with
the proper Blend Mode allows you to create styles that are
non-color-specific, meaning you can modify the color of the actual
layer, and your Layer Style will update appropriately.

Scaling Effects


There may be times when you’ve created a Layer Style that looks great
at the original size, but when the shape is increased or decreased,
your beautiful style is destroyed. Fortunately, Photoshop provides a
method to adjust styles that are out of whack. Simply choose Layer → Layer Style → Scale Effects, and then input the percentage you need.

Inconspicuous Menu Options


A number of hidden commands are available to you from within the
Layer Styles menu. Depending on the effect, you will have access to
either the Hand tool or the Move tool by simply mousing over the
document window. The Hand tool allows you to move the document around
just as you would outside the Layer Styles menu, and the Move tool
repositions the current effect and updates the settings automatically.
When using the Move tool, you can still access the Hand tool by holding
the space bar. While using either of the tools, you can zoom in and out
by holding Space + Cmd or Space + Option
respectively. Don’t forget, as with most other menus in Photoshop,
holding “Option” will change the “Cancel” button to a “Reset” button,
allowing you to undo any changes.
