A digital imaging program can be used to stack two pictures together. The technique used by these software applications can be used to achieve a relatively seamless integration of the two images. Adobe Photoshop is the most commonly used digital imaging program, but most comparable products can be used with similar results. There are varied methods used in the Photoshop program that can be employed to achieve the stacked photo effect, but all are based on the same basic techniques that can be tweaked for the achievement of a special effect. For example, if you want to insert a picture of someone in an exotic locale, then all the information around the person needs to be extracted with the Photoshop program. Extraction leaves the person's outline intact and ready to layer over the other picture.
Things You'll Need
- Adobe Photoshop or other comparable software
- Two digital pictures
Open both pictures in the digital imaging program. For this example, we shall continue with the scenario of the person superimposed in the exotic locale. Select the picture of the person and then drag the image with the move tool over to the other image, and drop it into the frame. Stacking the two pictures in this manner creates layers on one picture and frees the layer of the person from being locked as the background.
Select the magnetic lasso tool from the toolbar and trace the outline of the figure. Unlike the lasso tool, the magnetic lasso tool has a tendency to stick to areas of contrast; so a white shirt on a dark background will be easily traced. Once the whole outline has been drawn, use the move tool to grab the image and move it aside. Delete the remaining texture; all that will remain is the image inside of the selected area, namely the person.
Place the person in the position desired and then, if size adjustments need to be made, use the transform option to make the image larger or smaller. This technique is commonly used when the image of the person is not proportionate to the background. Once satisfied with the placement and size of the figure, use the zoom tool to ensure the edges of the transformed image are clean. Use a small brush setting on the eraser tool to smooth and clean up any jagged lines. When satisfied, flatten the image and save as a JPEG file.
