A soft glamour glow effect is incredibly useful when clients want to feel a little old-school Hollywood (think boudoir, wedding, and high school photography). In this column, you’ll learn how to use one of Photoshop’s oldest filters to quickly produce a soft and ethereal portrait effect that’s sure to please brides, prom queens, and princesses of any kind.
In Photoshop, choose File>Open as Smart Object to open a photo. If the photo is already open in Photoshop, or if it consists of multiple layers, activate the layer(s) and choose Filter>Convert for Smart Filters. This packages the active layer(s) into a single smart object. If you’re starting in Lightroom, select a photo and then choose Photo>Edit In>Open as Smart Object in Photoshop. [KelbyOne members may download the file used in this tutorial here. All files are for personal use only.]
TIP: If the photo to which you want to apply this effect consists of multiple layers, you can access the original layers later on by double-clicking the layer thumbnail for the smart object. When you do, Photoshop opens a separate, temporary document that contains all of your layers. Once you make your changes in that document, choose File>Save (not Save As) and then close the document, and your changes magically appear in the original document.
Since many Photoshop filters refuse to work with 16-bit imagery, it’s a good idea to ensure you’re working with an 8-bit image to start with. To do that, choose Image>Mode and make sure there’s a checkmark next to 8/Bits Channel. If there isn’t, go ahead and choose that menu item.
The filter you’ll use for this technique uses the Background color swatch at the bottom of the Toolbar for the glow color. Set it to white by pressing D on your keyboard to reset your Foreground and Background colors to their default settings of black and white, respectively.
Choose Filter>Distort>Diffuse Glow. If you don’t see the Distort option in the menu, choose Filter>Filter Gallery instead (Adobe shortened the Filter menu a few versions back, so you may be viewing an abbreviated filter list). In the resulting dialog, use the zoom buttons, beneath the lower left of the portrait preview, to adjust the zoom level so you can see the model. To the right of the portrait preview, click to expand the Distort section, and then click Diffuse Glow. On the right side of the dialog, drag the Graininess slider all the way to the left, set the Glow Amount to around 3, and set the Clear Amount to around 14. You’ll need to experiment with the Glow Amount and Clear Amount sliders on your own photos, but these settings are a good starting point. Click OK.
TIP: You can repopulate the Filter menu by going under the Photoshop (PC: Edit) menu and choosing Preferences>Plug-Ins and turning on the Show All Filter Gallery Groups and Names checkbox.
In the Layers panel, double-click the tiny icon to the right of the filter’s name (which will be Filter Gallery or Diffuse Glow, depending on the menu item you picked to open the filter in the first place). In the Blending Options dialog that opens, set the Mode pop-up menu to Luminosity to keep the photo’s colors from shifting. If you’d like, you can reduce the Opacity setting in this dialog to tone down the strength of the filter. Click OK.
TIP: You can also reopen the filter and experiment with different Diffuse Glow settings by double-clicking on the filter’s name in the Layers panel.
Now let’s hide the glow from certain parts of the photo. Click on the Smart Filters mask beneath the image layer in the Layers panel to activate it (white brackets appear around its thumbnail). Press B to activate the Brush tool and pick a soft-edged brush from the Brush Picker toward the left end of the Options Bar. Set the Size to around 100 pixels, and ensure the Mode pop-up menu is set to Normal and that Opacity and Flow are set to 100%. Whenever you’re working with a mask, painting with black conceals and white reveals, so to hide the filter effect, you need to paint with black. Press X on your keyboard until your Foreground color to black.
With that large, soft brush, paint across the background, the model’s dress, hair, teeth, and the iris of each eye. You can change your brush size as you paint by pressing the Left Bracket key ([) to decrease it or the Right Bracket key (]) to increase it. If you hide too much of the glow, press X on your keyboard to switch your Foreground color to white, and then paint that area again.
Choose File>Save to save the file. If you started in Lightroom, and you left it running while you worked in Photoshop, the new and glowing image shows up in your catalog as soon as you save it in Photoshop. To see before and after versions, click the visibility Eye icon to the left of the filter’s name in the Layers panel, and then turn it back on.
As you can see, this technique not only produces a soft, romantic image but also smooths your subject’s complexion nicely. Until next time, may the creative force be with you all!
