How to Make Glow-in-the-Dark in Photoshop
Adobe Photoshop is a powerful tool for enhancing and altering your digital images. Included with the software is a variety of quick-apply effects tools and visual filters, but the power of the software really lies in knowing how to combine the various capabilities of Photoshop to create all-new effects. Users can create things such as objects that appear as glow-in-the-dark figures by combining Photoshop tools.
Things You'll Need
- Digital image (preferably a darker composition)
Open your photo in Photoshop by opening the program and selecting “Open” from the File menu.
Click on the Layers palette at the right of the workspace and double-click on the “Background” layer to unlock it. Create a new layer by selecting the “Create a new layer” icon to the left of the trash can at the bottom of the Layers palette.
Select the new layer and select the Rectangular Marquee tool from the Tools panel. Click and drag a rectangle around the object you want to appear to glow in the dark.
Select “Edit > Fill” from the application menu and select “Color” from the “Use” drop-down menu in the “Contents” section. Select a color from the “Choose a color” for your glow. A yellowish-green is the classic color for a glow-in-the-dark effect, but you can use any color you like. Click “OK” to apply the fill to the rectangle.
Apply a layer mask to the rectangle by clicking the “Add a layer mask” icon at the bottom of the Layers palette. The icon is a rectangle with a circle in the center. Select the layer mask in the Layers palette.
Select the Brush tool and set the foreground color to black in the Tools panel. Select a Soft Round brush from the Tool options panel above the workspace and brush away the fill color around your glow-in-the-dark object so that the color left is a soft blob roughly following the lines of your object.
Return to the Layers palette and set the blend mode to “Lighter Color” in the drop-down menu in the upper left-hand corner of the palette. Set the “Opacity” slider on the upper right-hand corner of the palette to about 65 percent. Right-click ("Ctrl" and click on a Mac) on the thumbnail for the layer mask and select “Subtract mask from selection” from the fly-out menu.
Select “Select > Inverse” from the application menu to make a selection of everything outside the mask. Click on the original image layer in the “Layers” palette and select “Image > Adjustments > Brightness/ Contrast” from the application menu. Lower the brightness to darken the area outside the glowing portion of the image. This will make the glow-in-the-dark effect more pronounced.
Save your image by selecting “File > Save As.”
