How to Colorize a Black and White Photo

Adding color to a black and white photo used to require the skill of a trained colorist. With modern AI, the result is one click away. This guide covers the practical steps, the things to watch for, and how to get the best result for a specific type of photograph.

필요한 것

  • ✓A black and white or sepia photograph in JPG, PNG, TIFF, or WebP format.
  • ✓For best results, the source should be at least 1000 pixels on the long edge.
  • ✓A reference color photo from the same era is helpful but not required.

Step 1: Prepare the Source

Scan or export the photo at the highest available resolution. If the original is a print, scan at 600 DPI minimum. If the original is a digital file, use it as-is. Do not upscale before colorization - the model will produce better results on native resolution input.

Step 2: Choose the Right Model

Our colorization service offers two modes: automatic and era-guided. Automatic mode is best for general use. Era-guided mode lets you hint at the period (1920s, 1960s, 1980s) and the model adjusts the color palette accordingly. For most photos, automatic mode produces good results without any input.

Step 3: Run the Colorization

Click the Start Colorization button. The model takes 3-8 seconds to process. The result is shown in a side-by-side view. Compare carefully: skin tones should look natural, sky should be the right shade for the implied time of day, and clothing colors should be era-appropriate.

Step 4: Adjust if Needed

If the result has color issues (oversaturated sky, off skin tones, wrong era colors), re-run with a different mode or with the optional prompt. For example, "1940s outdoor portrait" will produce different results than "1980s indoor party".

Step 5: Post-Process

For the most natural result, apply a final color grade in your preferred editor. The model produces a flat colorization that benefits from a slight contrast boost and saturation adjustment. Avoid heavy-handed filters - the goal is to make the photo look like a color original, not an art piece.

전문가 팁

  • ★Group photos from the same era and run them through colorization together for a consistent look.
  • ★For portraits, the model performs better when the face is well-lit and at least 200 pixels wide.
  • ★Sepia-toned originals often colorize better than pure grayscale because the brown tint gives the model a hint about the era.
  • ★For archival projects, keep the original black and white version alongside the colorized result.
