Camera phones have a bias problem, and it’s baked into the physics of image processing. Auto-exposure algorithms, white balance and tone mapping were historically tuned around a narrow range of skin tones, leaving many faces washed out, muddied or simply misread. Tecno has spent the past few years chipping away at that, and its latest move pulls the effort out of the lab and into the world of art.
The company has teamed up with Brazilian visual artist Angélica Dass on a two-year initiative called 100 Portraits of Becoming. Dass is best known for Humanæ, her ongoing project matching human skin tones to Pantone swatches, so the pairing is a natural one: both artist and manufacturer are obsessed with rendering skin exactly as it is, not as a default algorithm assumes it should be.
The initiative builds directly on Tecno’s Universal Tone imaging technology, first introduced in 2023 to capture skin tones accurately across the full spectrum of human complexions. The following year the company launched its #ToneProud campaign to call out and fight skin-tone bias in smartphone cameras. Last year it expanded the Universal Tone multi-skin-tone color card to 372 skin tone patches — a reference library that tells the camera pipeline how to treat a face rather than guessing.
For the portraits themselves, the project leans on the Tecno Camon 50 Ultra, using the phone’s AI-powered mobile photography to shoot 100 subjects. It’s a smart choice of canvas: instead of demonstrating skin-tone accuracy on a spec sheet, the initiative puts it on the wall, where the difference between a face that’s genuinely represented and one that’s been flattened by generic processing is impossible to miss.
What makes this more than a marketing exercise is the through-line. Each step — Universal Tone, #ToneProud, the expanded color card, and now the Dass collaboration — treats accurate skin rendering as an engineering problem with a human answer. The 372-patch card isn’t a gimmick; it’s calibration data. And handing that pipeline to an artist whose entire practice questions how we categorize skin is a genuinely pointed test of whether the technology delivers.
- Initiative: 100 Portraits of Becoming, a two-year collaboration
- Artist: Angélica Dass, creator of Humanæ
- Core tech: Universal Tone imaging, with a 372-patch skin tone color card
- Capture device: Tecno Camon 50 Ultra with AI photography
It’s a refreshing angle in a market that usually measures cameras by megapixels and zoom range. Here the metric is simpler and harder: did the camera see the person in front of it correctly? On the evidence of Tecno’s escalating commitment, that question is finally getting the attention it deserves.
