Restoring a Portrait

It can be a lot of fun making sure your digital photographs look pristine and clear of intruding tourists. Photographs that tell a reliable story can capture a moment for a long time. Did you know that modern ink used in home printers is actually designed for archive use? Tests have shown that desktop printed documents are capable of surviving over 200 years. That’s a long time for you to be keeping pictures of Scruffy the dog, still wet from his first bath.

Some images, however, are priceless. They’re not printed on modern acid-free paper, using this state-of-the-art ink that makes us glad we’re not running our cars on anything made by Lexmark. These photographs are often of our own ancestors, the portrait surviving only because it has been behind glass for years, or was tucked into the attic for a couple generations, or sheer luck. Sometimes luck isn’t enough and time takes its toll despite our best efforts.


This is another image I found on the internet. There is an amazing amount of old photographs that have been scanned and uploaded onto the world wide web, and many of them are in similar condition to this. Age spots, mildew, water damage, creasing, wrinkles, and simply the changes in environment making the ink peel and flake off – many things can cause these minor bits of damage that grow to ruin the entire image. Soon, the portrait becomes unrecognizable and it goes from priceless to worthless. This effect is tragic, but correctable.

It used to be, before digital technology, that a skilled artisan needed to step in and take the original photograph to a laboratory. There, under a microscope or multiple magnifying glasses, the artist would carefully paint, cut, paste, and eventually repair the marred surface of the image. It was a painstaking process, not least of all because the artist was working with the original piece. If anything should happen, the photograph is gone, and is irreplaceable.

Nowadays, with scanners and other digital-capture devices (even your camera!), you can have something to work with and leave the precious original alone. To mimic the hard work performed by the artist mentioned previously, you simply need to use the methods I mentioned in the beach scene. You cannot erase the damaged sections, but you can take pixels from another section and paint over the flaw. Taking your time and envisioning what result you want will allow you to gradually restore the portrait to its prior glory. With the right training and a lot more time devoted to the project, it is even possible to improve on the original and clear up errors inherent in old photography – even adding color to a black-and-white portrait!

Here is the result of a few minutes’ work on this piece I found.


If you did not know it was originally damaged, it should be difficult to tell that anything has been done to the image. It is still very soft-focused, the colors are all the same, and lines that are supposed to be continuous do follow from one point to another without apparent disruption.

Just for comparison sake, here are the two images side-by-side.


Now if only we could make her smile…

We can. We’ll do that next week.
