Introduction
Old black and white photos can capture special memories and moments in time. However, color photos often feel more vibrant, lively, and closer to how we remember the actual events. Thankfully, technology has advanced to the point where it’s now possible to add color back into old black and white photos through digital colorization.
In this article, we’ll look at the different methods you can use to colorize old photos, the technological advancements that have made this possible, tips for getting the best results, and services that can help you revitalize your old family photos. With some simple steps, you can bring new life to vintage black and white images.
A Brief History of Photo Colorization
The process of adding color back into monochrome photos is known as photo colorization. This technique became popular in the 1980s as personal computers started to become common in households. Software programs like Adobe Photoshop began offering specialized tools that allowed users to manually colorize photos.
However, the process was extremely tedious. Artists would have to color each part of the photo pixel by pixel. It could take hours or even days to colorize a single image. This manual approach also required artistic skill and knowledge of colors, lighting, shadows, and textures to achieve a realistic effect.
In the 2000s, digital colorization advanced substantially thanks to machine learning and artificial intelligence. Computer algorithms were developed that could analyze the content of an image and apply colors much faster and more accurately than a human. This automatic approach made colorizing old photos far more accessible and practical for regular people to do at home.
Today, our smartphone apps leverage powerful AI to colorize photos in just seconds with a simple tap. Meanwhile, graphic designers use sophisticated software tools like Photoshop and DeOldify to produce strikingly realistic colorizations for historic images. The technology has improved enormously while also becoming easy enough for anyone to utilize.
How Does AI Photo Colorization Work?
AI photo colorization relies on deep learning algorithms that have been trained on millions of color images. The AI studies relationships between colors, textures, objects, shadows, lighting, and other elements in the sample photos. It learns to recognize patterns that can help predict appropriate color information.
When you provide the AI with a new black and white photo, it utilizes what it learned to analyze the grayscale image. It looks for textures and shapes that it recognizes from its training. This cues the algorithm on what colors would likely exist in those areas.
However, since multiple color possibilities could match a gray pixel, the AI also incorporates context. It considers what colors would logically fit the surrounding pixels and the overall scene based on the patterns it observed. This contextual reasoning enables it to generate colors that look natural and realistic.
The AI doesn’t always get it perfect on the first try. But many colorization tools let you make tweaks and adjustments until you get colors that you’re satisfied with. Overall, this automatic approach powered by deep learning produces colorized photos that would be extremely difficult to recreate manually.
Tips for Preparing Your Photos
To get optimal colorization results, it helps to start with the highest quality photo possible. Here are some tips for preparing your old black and white photos:
– Scan the original photo at a high resolution if you only have a physical print. This captures the most detail for the AI to analyze.
– Remove any stains, creases, or other damage on the original using photo editing tools before colorizing. This prevents the AI from mistaking damage for legitimate details.
– Adjust the brightness, contrast, and sharpness of the photo if needed so all elements are clearly visible. The AI relies on distinguishing fine details and textures.
– Crop out any notes, dates, or borders on the photo so the AI focuses entirely on the image content.
– If the photo contains family, research the hair and eye colors of the people so you can help guide the AI or make adjustments after.
Putting in effort to prep your photos will enable you to achieve more convincing, vibrant colorizations.

Colorization Software
For professional-level colorizing of vintage or historic photos, your best option is using advanced graphics and photo editing tools like:
Adobe Photoshop: The AI-powered Image Colorization tool in Photoshop can produce astonishingly realistic colorizations. It takes more work to mask regions and sample colors, but the control pays off in final image quality.
DeOldify: This free, open-source package uses deep learning to colorize and restore old images. It’s geared more toward programmers but they offer a Colab notebook that makes it accessible to anyone. The AI capabilities are very impressive.
AKVIS Coloriage: A dedicated colorization program with an intuitive interface for quickly revitalizing black and white photos. Works as a Photoshop or Lightroom plugin too. Provides different presets and lets you selectively apply color to regions.
Colorize Photos: An affordable app available on Mac and iOS. It utilizes AI to automatically generate colorizations. Includes tools for manually retouching colors, contrast, brightness, saturation, and more. Saves your progress so you can perfect the image over time.
The learning curve is higher with desktop software but they enable you to have full creative control over the colorizing process. This makes them ideal for restoring very special vintage photographs that you want to display.
Tips for Realistic Colorization
The AI algorithms do an amazing job applying suitable colors to old photos. However, you can take steps to enhance the realism and make the colorized photos look their absolute best:
– Leave some areas black and white. Selectively colorizing just the main subjects often looks more convincing than full colorization.
– Use historical references to research accurate colors for items like clothing, cars, buildings, etc. Don’t rely solely on AI guesses.
– Adjust the brightness, saturation, and color balance to match the scene lighting and aesthetic of the original era.
– Carefully colorize any skin exposed with natural tones. Use some soft textures and variations so skin doesn’t look flat and artificial.
– Manually refine details like hair, eyes, clothing patterns, and landscapes for a perfect finish. The AI won’t always capture fine distinctions.
– Add simulated film grain to make the final image match the vintage look of the original photo medium.
– Compare to the original and make sure you’re preserving the emotion and intention of the black and white version.
With some thoughtful enhancements and a quality source photo, you can achieve colorization results that look like they were originally taken in full color. The AI just provides the starting point but a human touch adds the final polish.
