A free and open-source camera app now rivals Google's Pixel camera capabilities.

Using unofficial software can be a double-edged sword - while it may offer certain freedoms, it often compromises on key features like camera performance. For those who value photo quality above all else, sticking with the stock Android version might seem like the only viable option, despite its drawbacks such as tracking and bloatware. However there's now an alternative that bridges this gap: a free and open-source camera app that's giving Google's Pixel camera capabilities a serious run for their money.

The quality of smartphone photographs has evolved beyond mere megapixels and camera lens size. While these factors still hold some significance, they no longer dictate the overall image quality. For instance, the Xiaomi 17 Ultra boasts a relatively large 1-inch sensor, yielding superior results compared to smaller sensors found in most other phones – although this particular model is not available in the US market. The disparity between images captured by high-end devices like Google Pixel and Samsung Galaxy, versus those from niche smartphones such as the Unihertz Titan 2 Elite, becomes apparent despite all three boasting approximately 50MP cameras.

The limitations of stock Android's camera processing are deeply ingrained in its proprietary code. When users opt for an alternative OS like LineageOS, their phone's native camera app is often swapped out for a generic open-source counterpart. This new software lacks the fine-tuning that makes flagship cameras shine, resulting in images that, while serviceable, can feel distinctly less polished than those from higher-end devices. Even with identical hardware, the difference can be jarring, akin to downgrading from a premium phone to a more budget-friendly option.

While some custom ROMs successfully integrate the stock camera application, users can also sidestep the problem by installing Google's camera app, albeit with considerable effort required. However neither of these alternatives is suitable for individuals transitioning to a custom ROM in pursuit of open-source software.

Several long-standing open-source camera applications exist, but their capabilities vary significantly. Open Camera stands out for its comprehensive feature set, allowing users to fine-tune settings according to their preferences. In contrast, the Fossify suite of open source apps takes a minimalist approach, providing limited customization options. As a result, users may find it restrictive if they're dissatisfied with the default output. A more recent alternative is PhotonCamera, which shows considerable promise as a viable stock camera app replacement. However its availability is restricted; it cannot be found in the Play Store or F-Droid by default. To access this app and others like it, users must add the IzzyOnDroid repository to their list of sources.

The PhotonCamera app captures multiple images in quick succession before combining them into a single high-quality image. This approach echoes the early days of Google Camera on Nexus devices, where users could opt for standard photos or wait briefly for HDR-enhanced shots. In contrast to this delayed process, the Pixel Camera now achieves similar results instantly. While PhotonCamera may not match the speed of its rival, it still offers a viable alternative with potential tweaks for capturing fast-moving subjects efficiently.

The image taken with the Google Pixel 10a's default camera software is juxtaposed against one captured by the Murena Fairphone 6, which is powered by PhotonCamera under /e/OS.

A side-by-side comparison reveals striking similarities in image quality between the stock camera app on a Moto Edge+ 2023, running LineageOS 23, and the PhotonCamera app on the same device.

On the same device, we're now comparing its camera capabilities with those of a magazine pile.

Generally speaking, images captured by the default camera app appear crisper, but PhotonCamera deliberately introduces more blurriness to create a shallower depth effect. This distinction becomes more pronounced when comparing high-resolution images on a desktop versus a mobile device's smaller display.

The PhotonCamera interface comes with a default purple gradient that doesn't quite resonate with me. Thankfully, it's simple to swap out for something more appealing. I usually head straight to settings, opting for the teal theme, which effectively eliminates the gradient. Grid lines are also readily available, providing valuable assistance in framing your shot according to established composition principles. You can choose between JPG and RAW formats for saving your photos, while noise reduction is easily disabled. The app's flexibility extends to adjusting sharpness, saturation, contrast, and exposure levels to suit your desired aesthetic.

Advanced users have direct access to essential features via the viewfinder, including a countdown timer and flash activation. Controls typically reserved for "pro" modes in standard apps are also readily available, like manual ISO and exposure adjustments.

A cluttered workspace can be overwhelming and my desk is no exception. Currently, I have a collection of phones scattered each one begging for attention. Although PhotonCamera might work on devices like the Fairphone 6 and Moto+ 2023, others such as the Unihertz Titan 2 Elite or Bigme Hibreak Pro Color are not compatible. The best way to determine support is to download the app directly. Fortunately, this service comes at no cost.
