CTOnews.com, November 15 (Xinhua)-- DXOMARK announced on its official Weibo yesterday that it will launch DXOMARK Insight Service, which aims to collect consumers' pain points and feedback, provide manufacturers with effective data and analysis, and at the same time bring a better experience to consumers.

▲ source DXOMARK official Weibo DXOMARK Insight focuses on "portrait photography" in the first issue, and officials say that because DXOMARK's oldest technical expertise is in testing image quality, in the first study, officials will focus on the performance of smartphones on skin color when taking photos.

It is reported that DXOMARK stressed that the main challenges of portrait photography are "scale exposure, contrast and skin color".

In portrait photography, skin color is one of the biggest challenges when shooting color, exposure, color and contrast are also important factors for accurate skin color, and exposure is the most critical factor:

The camera needs to shoot motion, which means it must absorb as much information (light) as possible in a very short period of time.

The power of a full-frame hybrid camera is that it can capture the maximum amount of light in milliseconds.

Photos taken by ▲ DXOMARK using Samsung Galaxy S23 phone DXOMARK took a series of photos using Samsung Galaxy S23 phone and said that different skin colors bring different technical challenges to each scene. Each tone changes the contrast of the image and makes the correct exposure more tricky.

As a result, when portrait photography focuses on smartphone images, even the sensor size of today's top smartphones is 10 times smaller than that of SLR cameras, so the challenge is completely different.

Smartphones must automatically do everything for users! In addition, they need to use small sensors in low light conditions and freeze the moment, while avoiding facial shearing and providing a good dynamic range.

CTOnews.com learned from the report that DXOMARK believes that in order to improve the effect of mobile portrait photography, manufacturers mainly design "layers of intertwined lenses" (aperture up to f / 1.4), and apply a lot of artificial intelligence to achieve "computational photography", so as to "combine professional cameras and professional photographers into one", and then improve the "performance of skin color presentation". And these achievements have been reflected in a considerable number of smartphones in the current period.

In addition, DXOMARK also conducted a survey of smartphone users, the results showed that family, friends and pets accounted for more than 50% of users, on average, only 17% of respondents' photos were related to travel, and life / food themes accounted for an average of 9%, so DXOMARK believes that "portrait effect" is very important for smartphone manufacturers.
