How to colorize a black and white photo

Grandparent wedding photos, historical family portraits, vintage travel snapshots — black and white images feel distant. AI colorization brings them to life with realistic, historically accurate color that makes old photos feel immediate and personal.

How AI colorization works — Magic Eraser

Traditional colorization is a painstaking manual process — artists in Photoshop paint color onto grayscale images layer by layer, researching period-accurate clothing colors, skin tones, and environmental hues. A single portrait takes 2-4 hours of skilled work. AI colorization uses deep learning models trained on millions of color photographs to understand what colors belong where — skin tones vary by lighting and ethnicity, skies follow weather patterns, grass and foliage have seasonal variation, fabric colors match era-appropriate fashion palettes. The AI analyzes the grayscale luminance values and texture patterns to infer the most likely original colors, producing results in seconds that rival hours of manual work.

ขั้นตอนการใช้งาน

  1. 1

    Upload the black and white photo

    Open Magic Eraser on web, iOS, or Android. Upload your grayscale image — a scanned family photo, a historical image, a vintage portrait, or any black and white photograph. JPEG, PNG, and TIFF accepted. Higher resolution scans produce better colorization results.

  2. 2

    Select AI Colorize

    Choose the colorization tool from the enhance menu. The AI analyzes the image content — identifying faces, clothing, sky, vegetation, architecture, and other elements — then applies historically and contextually appropriate colors to each region.

  3. 3

    Review and adjust

    The AI produces a fully colorized version in seconds. Skin tones, fabric colors, sky hues, and environmental elements are colored based on the AI's analysis of the image content. Review the result and export at full resolution. For best results, start with the highest quality scan of the original.

เคล็ดลับเพื่อผลลัพธ์ที่ดีที่สุด

Scan quality matters significantly for colorization. Scan at 600 DPI or higher if possible — the AI needs detail to distinguish between different textures and surfaces that should receive different colors. Clean the photo before scanning to remove dust and debris. If the original print is faded or low-contrast, use the AI enhancement tool first to improve the grayscale range before colorizing — this gives the colorization AI better luminance data to work with. For group photos, the AI handles multiple skin tones accurately. For landscapes, the AI infers season from foliage density and sky conditions. Historical accuracy is approximate — the AI produces plausible colors based on era and context, but specific garment colors are inferred, not known.

คำถามที่พบบ่อย

How accurate are the colors?
The AI produces historically plausible and visually natural colors. Skin tones, sky colors, and vegetation are highly accurate. Specific garment colors are inferred from context and era — the AI can't know the exact color of a specific dress, but it assigns appropriate period colors.
Does it work on very old photos (1800s)?
Yes. The AI handles photos from any era. Earlier photographs (daguerreotypes, tintypes, albumin prints) may have different tonal ranges that affect results, but the AI adapts to the specific characteristics of each image.
Can I adjust the colors after colorization?
The AI produces its best estimate in one pass. For specific color adjustments (making a sky bluer or a dress a different color), you can use additional editing tools after the initial colorization.
Is colorization free?
Yes. AI colorization is available on the free tier with daily usage limits. Premium plans remove limits for volume colorization projects.
