Fairphone 4 Camera test

We put the Fairphone 4 through our rigorous DXOMARK Camera test suite to measure its performance in photo, video, and zoom quality from an end-user perspective. This vendible breaks lanugo how the device fared in a variety of tests and several worldwide use cases and is intended to highlight the most important results of our testing with an pericope of the captured data.

Pros

  • Low noise levels in unexceptionable light and indoor conditions
  • Good detail in unexceptionable light
  • Accurate white balance

Cons

  • Underexposure
  • Limited dynamic range
  • Unnatural rendering of visionless skin tones (reddish cast)
  • Lack of detail in indoor and low light images
  • Strong white wastefulness tint on night shots with flash
  • No bokeh mode
  • Narrower field of view on ultra-wide than many competitors

Following on the Fairphone 3, the Fairphone 4 is the latest iteration of the company’s sustainable smartphone and comes with overall refreshed hardware, including the wing of an ultra-wide camera and a wider vent on the primary camera. Both camera modules use 48MP 1/2″ image sensors.

Despite the technology update, the Fairphone 4 does not come tropical to the category leaders Google Pixel 6 and Apple iPhone SE and occupies one of the lower spots in the DXOMARK Camera ranking for High-End smartphones. When shooting still images, the camera produces well-judged white wastefulness and controls noise well in unexceptionable light and under indoor conditions. However, the Fairphone 4 is held when by frequent underexposure and a lack of image detail.

The Fairphone 4 does not come with a defended tele module and as a result, tele image quality leaves some room for improvement. On the plus side, the ultra-wide is capable of achieving decent image results in the right conditions. The field of view is not quite as wide as on many competitors, though.

When recording video, the Fairphone delivers the weightier results in unexceptionable light and static scenes. In such conditions, footage shows pleasant colors, a neutral white balance, and an winning level of detail. Video stabilization is pretty constructive as well. However, with moving subjects in the scene, autofocus instabilities, sharpness differences between frames and noise wilt noticeable, expressly in low light.

Test summary

About DXOMARK Camera tests: DXOMARK’s Camera evaluations take place in laboratories and in real-world situations using a wide variety of subjects. The scores rely on objective tests for which the results are calculated directly by measurement software on our laboratory setups, and on perceptual tests in which a sophisticated set of metrics indulge a panel of image experts to compare aspects of image quality that require human judgment. Testing a smartphone involves a team of engineers and technicians for well-nigh a week. Photo, Zoom, and Video quality are scored separately and then combined into an Overall score for comparison among the cameras in variegated devices.

About DXOMARK Camera Photo tests

For scoring and analysis, DXOMARK engineers capture and evaluate increasingly than 2,600 test images both in controlled lab environments and in outdoor, indoor and low-light natural scenes, using the camera’s default settings. The photo protocol is designed to take into worth the main use cases and is based on typical shooting scenarios, such as portraits, family, and landscape photography. The evaluation is performed by visually inspecting images versus a reference of natural scenes, and by running objective measurements on images of charts captured in the lab under variegated lighting conditions from 1 to 1,000 lux and verisimilitude temperatures from 2,300K to 6,500K.

[glossary_exclude]Fairphone 4 Photo scores vs High-End[/glossary_exclude]
The photo tests unriddle image quality nature such as exposure, color, texture, and noise in various light conditions. Autofocus performances and the presence of artifacts on all images captured in controlled lab conditions and in real-life images are moreover evaluated. All these nature have a significant impact on the final quality of the images captured with the tested device and can help to understand the camera's main strengths and weaknesses.

Exposure and verisimilitude are the key nature for technically good pictures. For exposure, the main symbol evaluated is the splendor of the main subject through various use cases such as landscape, portrait, or still life. Other factors evaluated are the unrelatedness and the dynamic range, eg. the worthiness to render visible details in both unexceptionable and visionless areas of the image. Repeatability is moreover important, considering it demonstrates the camera's worthiness to provide the same rendering when shooting several images of the same scene.
For color, the image quality nature analyzed are skin-tone rendering, white balance, verisimilitude shading, and repeatability. For verisimilitude and skin tone rendering, we penalize unnatural colors but we respect a manufacturer's nomination of verisimilitude signature.

Autofocus tests concentrate on focus accuracy, focus repeatability, shooting time delay, and depth of field. Shooting wait is the difference between the time the user presses the capture sawed-off and the time the image is unquestionably taken. It includes focusing speed and the sufficiency of the device to capture images at the right time, what is tabbed 'zero shutter lag' capability. Even if a shallow depth of field can be pleasant for a single subject portrait or close-up shot, it can moreover be a problem in some specific conditions such as group portraits; Both situations are tested. Focus verism is moreover evaluated in all the real-life images taken, from infinity to close-up objects and in low light to outdoor conditions.
