How to combine photos in Photoshop Elements
1 Create a new document
Go to File>New>Blank File, and from the drop-down menu choose a suitable document size for all your images (we chose A3 from the International Paper options). Rotate the canvas 90°, go to Edit>Fill Layer and choose Black.
2 Open your images
Now you can open the images that you took. Open each image in turn, then select it (Ctrl+A) and copy it to the clipboard (Ctrl+C). Next, go back to your original document and paste the image onto it (Ctrl+V).
3 Move and Transform
Before you open the next image, go to Image>Transform>Free Transform and make sure Constrain Proportions is ticked. Then drag one of the corner tabs to resize the image and drag it into the correct position on the canvas.
4 Final adjustments
By repeating steps 2 and 3 for each image you’ll have the basic composite, but you may need to rotate individual layers to make them fit with the images around them. Select them and go to Image>Rotate>Free Rotate Layer.
