Step-By-Step Instructions:
1. Using your scanner, scan in the torn photo so that it is an image file.
2. Open the image of the torn photo into Photoshop.
3. Goto Image > Mode > RGB to make sure you are in an mode that allows you to edit with multiple layers.
4. Select the Polygonal Lasso tool.
5. Use the Lasso tool to create a selection around the left half of the torn photo.
6. Click CTRL+X to cut the selection.
7. Click CTRL+V to paste the selection onto a new layer.
8. With the new layer selected, click CTRL+T. This will put you into Free Transform mode.
9. Now move your cursor to the corner of the photo and when you see your cursor change to the rotation icon, then click down and drag to straight out the photo (do this same step to the other side of the photo on the other layer if needed).
10. With both layers straightened, select one of the layers and move them so that they line up to create a complete photo.
11. The tear might remove some of the photograph, so we'll repair this in the following steps.
11. Goto Layer > Flatten Image to merge all the layers.

17. Select the Paint Brush tool. Choose a small brush size. Zoom in on the eye (or other area that was destroyed in the photo) that needs to be fixed.
18. Hold down the ALT key, then select a color of what's left of the eye (or other feature that was destroyed in the photo) to bring it in as your foreground color.
19. Begin redrawing the eye or other features that were destroyed.
