How to colorize black and white photos
Start with a clean scan
Colorization works best on a high-quality scan. Scan the print at 600 DPI or higher so the tool has all the tonal detail to map color onto. A weak, low-resolution scan produces flat, unconvincing color.
Repair first, then color
If the photo is faded, scratched, or torn, restore it before or alongside colorizing. Correcting contrast and removing damage gives the colorization cleaner tones to work with and a more believable result.
Automatic colorization
An AI tool analyzes the grayscale values and applies realistic color to skin, clothing, foliage, and sky automatically, keeping the original detail intact. It removes the painstaking manual masking that hand-colorization requires.
Keep the original
Always keep your original scan. Colorization is an interpretation, so preserving the untouched grayscale file lets you re-run it later or keep the historical version alongside the colorized one.
Frequently asked questions
Can black and white photos be colorized realistically?
Yes. Modern AI colorization maps realistic color onto skin, clothing, and backgrounds based on the photo's tonal values, keeping the original detail intact. Start from a high-resolution scan for the best result.
What DPI should I scan a black and white photo before colorizing?
Scan at 600 DPI or higher so the tool has maximum tonal detail to map color onto. Low-resolution scans produce flat, unconvincing color.
Should I restore a photo before colorizing it?
Yes, if it is faded or damaged. Correcting contrast and removing scratches first gives the colorization cleaner tones and a more believable result.
