Learn How to Combine Photos in Photoshop

Understanding Photoshop's Layer Foundation for Photo Combining

Before you can successfully combine photos in Photoshop, you need to understand how the software organizes visual information into layers. Think of layers like sheets of transparent film stacked on top of each other. Each photo you bring into your project sits on its own layer, and you can move, resize, or blend them without affecting the others. This is fundamentally different from working in simpler image editors where everything flattens into one image immediately.

When you start a new Photoshop document, you begin with a blank canvas. Every photo you add becomes a new layer. The Layers panel (usually visible on the right side of your screen, or accessible through Windows > Layers) shows you all your layers stacked vertically. The layer at the top of the panel appears on top of your image visually. The layer at the bottom appears behind everything else. You can reorder layers by dragging them up or down within the panel, which instantly changes what appears in front and what appears behind.

Each layer has an opacity setting, which controls how transparent or solid it is. A layer at 100% opacity is completely solid and blocks everything behind it. A layer at 50% opacity is half-transparent, allowing you to see the layers underneath. This becomes crucial when combining photos because you can make one photo semi-transparent to create blending effects, double exposures, or subtle overlays. You'll also see a small eye icon next to each layer in the Layers panel. Clicking this icon hides or shows that layer without deleting it, which helps you focus on specific parts of your composition while working.

Practical takeaway: Open Photoshop and create a new document. Place at least three different photos as separate layers and practice reordering them by dragging in the Layers panel. Adjust the opacity of the top layer to 50% and observe how the layers beneath become visible. This hands-on exploration builds the mental model you need for all combining techniques that follow.

Importing Multiple Photos as Layers in One Document

The most straightforward way to combine photos is to open them all in a single Photoshop document as separate layers. There are several methods to do this, and understanding each one helps you work more efficiently depending on your situation. The method you choose depends on whether you're starting fresh or already have a document open, and how many photos you're combining.

If you're starting from scratch, one efficient approach is to use File > Scripts > Load Files into Stack. This feature opens a dialog where you can select multiple image files at once from your computer. Photoshop then creates a new document and places each selected image on its own layer automatically. This saves significant time compared to opening files one at a time and manually copying them into a single document. The script arranges layers with the first selected file at the bottom and the last selected file at the top.

Another method is to open your first photo normally (File > Open), then add additional photos as layers by going to File > Open as Layers. This dialog works like a standard file browser where you can select multiple files by holding Ctrl (Windows) or Command (Mac) while clicking each filename. When you confirm, Photoshop places each selected image as a new layer in your existing document. This approach works well when you've already decided on your canvas size and want to bring in additional images to combine.

You can also create a new blank document with your desired dimensions (File > New), then drag and drop photos directly from your file explorer or desktop into the Photoshop window. When you drop an image, Photoshop asks if you want to place it as a smart object or as regular pixels. Placing as a smart object preserves the original image data, allowing you to resize it without losing quality. Placing as regular pixels means the image becomes rasterized at its current size. For combining photos where you might need to resize elements, smart objects offer more flexibility later in your workflow.

Practical takeaway: Gather five photos you want to combine and use File > Open as Layers to bring them all into a single 1200×800 pixel document. Arrange them in a visually interesting order (not necessarily chronological). Practice hiding and showing layers using the eye icon to visualize different arrangements before deciding on your final composition.

Resizing and Positioning Your Combined Photos

Once your photos exist as layers in the same document, you'll almost certainly need to resize and reposition them to create a cohesive composition. A photo imported as a layer may be much larger or smaller than your canvas, or positioned off to one side. The Transform tools in Photoshop let you scale, rotate, and move layers until they fit your vision for the combined image.

To resize a layer, first select it by clicking on it in the Layers panel. Then go to Edit > Free Transform (or press Ctrl+T on Windows, Command+T on Mac). This activates the transform bounding box—a frame with handles around your layer. You can drag the corner handles to resize the layer. Hold Shift while dragging a corner to maintain the image's original proportions, which prevents distortion. Drag from the center point to resize from the middle outward, or drag from the edges to resize from that direction. When you're satisfied with the size, press Enter or click inside the bounding box to confirm.

If you need to rotate a layer, activate Free Transform again, then move your cursor slightly outside one of the corner handles. The cursor changes to a curved arrow, indicating rotation mode. Click and drag to rotate the layer. This is useful when combining photos at angles for a dynamic, creative composition. You can also use Edit > Transform > Rotate to access preset rotation options like 90° clockwise or flip horizontally, which is faster when you know exactly what rotation you need.

To move a layer around your canvas, select the Move tool from the toolbox on the left (or press M). With your desired layer selected in the Layers panel, click and drag directly on that layer in the main image to reposition it. The Move tool only affects the currently selected layer, so you can move each photo independently without disturbing the others. When combining photos, you'll likely spend considerable time with the Move tool, fine-tuning positions until the composition feels balanced. Pay attention to how elements from different photos interact—do they overlap in interesting ways? Do they create leading lines or visual flow?

Practical takeaway: Take one of the photos you imported in the previous exercise and practice resizing it using Free Transform while holding Shift to maintain proportions. Rotate it 15 degrees, then reposition it to a corner of your canvas. Repeat this process with another layer, creating a small grid or collage layout. Notice how the layering creates depth when images overlap.

Creating Seamless Blends Using Layer Masks and Opacity

When photos sit directly on top of each other with hard edges, the combination often looks cut-and-paste rather than integrated. Layer masks and opacity adjustments transform separate images into cohesive compositions by creating smooth transitions between them. A layer mask is an invisible control that determines which parts of a layer are visible and which parts are transparent, without actually deleting any pixels from the layer itself.

To add a layer mask, select the layer you want to mask in the Layers panel, then click the rectangle icon at the bottom of the Layers panel (it looks like a small square). Photoshop adds a white rectangle next to your layer's thumbnail—this is your mask. A white mask means the entire layer is visible. A black mask means the entire layer is invisible. Gray areas in the mask create partial transparency. The key insight is that you can paint on the mask with any shade of gray (or black or white) to control visibility, and this is completely reversible. Painting on the mask doesn't destroy the actual image.

To create a subtle blend along the edge where two photos meet, select your layer mask (click on the white rectangle in the Layers panel), then choose the Gradient Tool from the toolbox. Set your foreground color to black and your background color to white. Drag the gradient across the edge where you want the transition to happen. The gradient creates a smooth fade from opaque (white) to transparent (black), blending one photo into another seamlessly. This technique is foundational for creating composite images that don't look obviously photoshopped.

Layer opacity offers a simpler but equally powerful approach for blending. Select any layer and adjust the Opacity slider at the top of the Layers panel. Reducing a layer's opacity to 70% or 50% makes it semi-transparent, allowing layers beneath to show through. This creates ethere
