Restore a damaged photograph - choose one that Mrs. Olden provided or one of your own.
- Scan image (use 300-600 ppi)
- Open in Photoshop
- Crop & Straighten image
- Duplicate Background layer and rename it 'retouch'
- If the image is black & white it may be helpful to use the B&W adjustment layer to removes color cast when retouching. You can add toning (like sepia) back later.
- Make exposure adjustments (look at histogram to get a good range of tones)
- Zoom in and start working on the image using retouching tools. (healing brush, spot healing brush, clone stamp, patch tool)
- Sometimes you need to try different tools to get it right.
- Also changing settings for the same tool might help (size, normal vs content aware vs proximity match) often helps.
- Zoom out and turn layer on and off to see 'before' vs 'after'.
- Add any color back using adjustment layers OR 'colorize' your image.
- Yay- hopefully it looks beautiful!
