Why do you take pictures of food and makeup with your mobile phone? Revealing the color science behind photography
In recent years, the camera functions of mobile phones have become more and more powerful, but many users have discovered a strange phenomenon: even though they are wearing exquisite makeup, the photos taken by mobile phones look "makeup-stricken", and the colors are dim or even distorted. Why is this? This article will analyze this phenomenon from a technical perspective and attach the hot topic data of the entire network in the past 10 days for reference.
1. Three core reasons for taking photos, eating and makeup with mobile phones
1.Automatic white balance algorithm intervention: The mobile phone camera will automatically correct the color temperature through algorithms, tending to restore "natural skin color", causing the makeup color to be neutralized.
2.HDR multi-frame synthesis technology: To preserve highlight and shadow details, the phone will automatically merge multiple photos with different exposures, which may reduce color saturation.
3.Beauty optimization of front camera: Most mobile phone front cameras will activate the skin grinding and noise reduction functions by default, directly weakening the texture details of makeup.
| Influencing factors | Specific performance | solution |
|---|---|---|
| White balance algorithm | Lipstick turns pink and eyeshadow looks dirty | Manually lock white balance |
| HDR compositing | Color loss in highlights | Turn off automatic HDR |
| Beauty function | Contouring lines are blurred | Disable AI beautification |
2. Related data of hot topics on the entire network (last 10 days)

3. Professional solutions
1.Manual mode settings: In professional mode, fix the white balance at about 5500K and increase the saturation appropriately (+1~2 stops).
2.Light environment selection: When shooting under natural light, avoid strong light at noon. It is recommended to use a ring fill light indoors (color temperature 2700K-4000K).
3.Post-retouching techniques: Use apps such as Snapseed to individually enhance lip/eye shadow saturation and sharpen local structures to enhance details.
4. Manufacturer’s technology improvement trends
According to the latest industry news, OPPO, vivo and other manufacturers have launched a "beauty color protection mode" in new phones in 2024, which uses AI to identify makeup areas and optimize them individually. Laboratory tests show that this technology can increase the color of blush by 67% and the clarity of eyeliner by 89%.
It is worth noting that the “Pro Camera Palette” function has also been added to the beta version of Apple’s iOS 18, allowing users to customize the color mapping curve, which is expected to effectively alleviate the problem of eating makeup.
With the development of computational photography technology, the color restoration capabilities of mobile phone photography will usher in breakthrough progress in the next 2-3 years. It is recommended that consumers focus on key technical indicators such as "color engine" and "multispectral sensor" when purchasing new phones.
