Create collages, montages | Photoshop, Photoshop Elements

Choose File > New to create a new blank image. Specify image size based on the desired print size (such as 8 inches x 10 inches at 150 pixels per inch on a white background).

Note: If your images differ in resolution or pixels per inch, they could display at an unexpected size in the collage image. You can use the steps below on transforming layers to resize the images appropriately. See online Help for more information about resolution.

Choose File > Open, and open the first image (Image 1) to be added to the collage image. You now have the collage image and the first image (Image 1) open at the same time.

Select the Move tool. Click anywhere within Image 1, drag from the Image 1 window to the collage image window, and release the mouse button. Image 1 displays in the collage image window. Image 1 is on a new layer, called Layer 1.

Double-click the words "Layer 1" in the Layers panel, and rename Layer 1 so that you can track your layers.

Close the Image 1 window so that only the collage image is open. Your Layers panel now contains a Background layer and the new layer that you renamed.

In the Layers panel, click once on the layer that you want to adjust, to target the layer.

Choose Edit > Free Transform (Photoshop) or Image > Transform > Free Transform (Photoshop Elements).

Note: Before you transform your layer, make sure that the correct layer is targeted in the Layers panel.

Note the bounding box around the edges of the layer and the anchor points on all four corners and sides (eight total).

• Resize the layer by dragging the anchor points. 

• Reposition the layer by clicking inside the bounding box and dragging.

  Note: If a layer displays larger than the collage image, drag the layer in any direction until you can see a corner of the image. You can then transform the image using the anchor point on the visible corner.

• Rotate the layer by positioning your cursor just outside the bounding box, clicking, and dragging. You can rotate the layer when your cursor changes to a curved double-headed arrow.
• In the option bar at the top of the screen, click the check box to accept or commit the transformation. Or, click the circle with the slash through it to cancel the transformation.
