The two ways to add a shadow in Photoshop

Photoshop gives you two main paths to add a shadow: Drop Shadow, which puts a shadow behind an object as if light is hitting it from the front, and Inner Shadow, which puts a shadow inside the edges of a shape or text, making it look recessed. Drop Shadow is what most people reach for first because it works on anything — text, photos, shapes, entire layers. Inner Shadow is less common and works best on solid shapes or text with a filled background.

Both live in the same menu and use the same controls once you open them. The difference is where the shadow falls and what it makes look like. Drop Shadow makes things pop forward. Inner Shadow makes things look pressed into the page.

This guide covers Drop Shadow first because it is the one you will use most often. The steps are nearly identical for Inner Shadow, and we cover those differences at the end.

Key Takeaways

  • Drop Shadow sits in the Layer menu under Layer Style, and you can explore it to text, shapes, or photos without flattening or merging anything first.
  • The four controls that matter most are Opacity (how dark the shadow is), Distance (how far it sits from the object), Blur (how soft or sharp the edge is), and Angle (which direction the light comes from).
  • Photoshop starts you with settings that work for most situations, so you can often just click OK without changing anything.
  • You can edit or remove a shadow later by going back to Layer Style — the shadow is not permanent until you flatten the image.

How to add a drop shadow to text or a shape

Click the layer you want to shadow in the Layers panel on the right side of the screen. If you do not see the Layers panel, go to Window at the top and click Layers. Make sure you are on the layer that holds the text or shape, not a background layer.

Go to the Layer menu at the top, hover over Layer Style, and click Drop Shadow. A window will open with a preview of the shadow on your image. Photoshop applies a default shadow when ready — usually a soft, dark shadow sitting slightly below and to the right of your text or shape. In most cases, this default is fine and you can click OK to accept it.

If you want to change how the shadow looks, adjust the sliders in the Drop Shadow window. The most useful ones are Opacity (drag it left to make the shadow lighter, right to make it darker), Distance (how far the shadow sits from the object), and Blur (how soft the shadow edge is). Angle controls which direction the light comes from — 90 degrees is straight down, 0 degrees is from the right, 180 degrees is from the left. Once you are happy with the preview, click OK.

Adding a shadow to a photo or complex image

Drop Shadow works on photos too, but it shadows the entire layer, not just the subject. If your photo sits on a transparent background (you can see a checkerboard pattern behind it), the shadow will appear around the whole rectangular layer, not just around the person or object in the photo.

If that is what you want — a shadow around the whole photo frame — follow the same steps: select the layer, go to Layer menu → Layer Style → Drop Shadow, and adjust as needed. If you want a shadow only around the subject (the person, the car, the flower), you need to first select just that subject using the selection tools. Click the layer, then use the Quick Selection tool or the Lasso tool to outline only the part you want to shadow. Once the selection is active, go to Layer menu → Layer Style → Drop Shadow. The shadow will now follow your selection instead of the whole layer.

Understanding the Drop Shadow controls

The Drop Shadow window has more sliders than you need. Here is what each one does and which ones actually matter:

Blend Mode controls how the shadow mixes with what is underneath. Multiply is the default and works for almost everything. Change this only if the shadow looks wrong against your background color.

Opacity is how dark the shadow is, from 0 (invisible) to 100 (solid black). Start at 75 percent. Lower it if the shadow looks too harsh, raise it if it is too faint.

Angle is the direction the light comes from, measured in degrees. 90 degrees means light from above (shadow below). 45 degrees means light from the upper right (shadow to the lower left). Most designs use 90 or 120 degrees. You can also click the small circle in the preview and drag it to set the angle visually.

Distance is how far the shadow sits from the object, in pixels. 5 to 15 pixels works for most screen designs. Larger distances (30+) make the shadow look farther away. Set it to 0 if you want the shadow directly underneath with no offset.

Spread makes the shadow larger or smaller before it blurs. Leave this at 0 for most work. Raise it only if you want a harder-edged shadow.

Size is how much the shadow blurs, in pixels. This is the most important control for how soft or sharp the shadow looks. 5 to 10 pixels gives a soft, natural shadow. 20+ pixels gives a very soft glow. 0 pixels gives a hard shadow with no blur.

Editing or removing a shadow after you create it

Shadows in Photoshop are not permanent. As long as you have not flattened the image, you can go back and change the shadow anytime. Click the layer that has the shadow, go to Layer menu → Layer Style → Drop Shadow, and the window opens again with your current settings. Adjust anything you want and click OK.

To remove the shadow entirely, click the layer, go to Layer menu → Layer Style → Drop Shadow, and click the Delete button at the bottom of the window. The shadow disappears but the layer stays intact.

If you want to copy a shadow from one layer to another, right-click the layer that has the shadow, click Copy Layer Style, then right-click the layer you want to paste it to and click Paste Layer Style. This is faster than recreating the same shadow twice.

How to add an inner shadow

Inner Shadow works the same way as Drop Shadow but puts the shadow inside the edges instead of outside. It is useful for making text or shapes look pressed into the page or carved out. Click the layer, go to Layer menu → Layer Style → Inner Shadow. The controls are identical — Opacity, Angle, Distance, Blur, and Size all work the same way.

Inner Shadow works best on solid shapes or text with a filled background. On photos or transparent layers, it usually looks odd because it shadows the entire layer edge rather than a specific object. If you want an inner shadow on just part of a photo, select that part first using the selection tools, then explore Inner Shadow.

You can use both Drop Shadow and Inner Shadow on the same layer. Click the layer, go to Layer Style, and check both boxes. This creates a shadow on the outside and inside edges at the same time, which can look striking on text or buttons.

Common mistakes and how to avoid them

The most common mistake is making the shadow too dark or too large. Photoshop's default settings are conservative on purpose — they work in most situations. If you change Opacity above 90 or Size above 20, the shadow usually starts to look fake or overwhelming. Start with the defaults and make small changes.

Another mistake is forgetting that shadows need contrast to be visible. A dark shadow on a dark background is invisible. If your shadow is not showing up, check the background color. Raise the Opacity or lower the Blur to make it more visible, or change the Angle so the shadow falls on a lighter part of the background.

A third mistake is explore the shadow to the wrong layer. If you have a background layer and a text layer on top, make sure you click the text layer before opening Layer Style. Shadows explore only to the layer you have selected.

Frequently Asked Questions

Can I save a shadow and use it on other images?

Yes. Create the shadow you want on any layer, then right-click that layer and click Copy Layer Style. Open another image, click the layer you want to shadow, right-click, and click Paste Layer Style. The shadow settings copy over exactly. You can also save a set of layer styles as a preset by going to Window → Styles and clicking the New Style button.

Why does my shadow look blurry or soft even though I set Size to 0?

Photoshop's anti-aliasing (edge smoothing) can make even a 0-blur shadow look slightly soft on screen. If you need a completely hard-edged shadow, lower the Opacity to make it less noticeable, or use a different approach like drawing a shape and filling it with a solid color.

Can I add a shadow to just part of a layer?

Yes, but you have to select that part first. Use the Quick Selection tool, Lasso tool, or any other selection tool to outline the area you want to shadow. Once the selection is active (you will see marching ants around it), go to Layer menu → Layer Style → Drop Shadow. The shadow will follow your selection instead of the whole layer.

What is the difference between Drop Shadow and Outer Glow?

Drop Shadow creates a dark shadow that looks like it is cast by an object. Outer Glow creates a colored halo around an object, usually lighter and more diffuse. Drop Shadow is for depth and realism. Outer Glow is for emphasis or a glowing effect. They are separate options in the Layer Style menu.

Do I have to flatten my image to keep the shadow?

No. Shadows stay attached to the layer as long as the file is in Photoshop format (.psd). If you export to .jpg or .png, the shadow becomes permanent and part of the image. If you save as .psd, you can always reopen the file and edit the shadow later.
