In-depth Analysis of Professional Mode in Mobile Photography: From Parameters to AI Assistance, Ushering in a New Era of Image Creation

The rapid advancement of mobile phone photography in recent years is undeniable. This progress is attributed not only to the continuous iteration and upgrading of AI algorithms but also to the rapid development of hardware technology. Larger sensors, higher-magnification telephoto lenses, and more powerful image processing modules have jointly built a solid foundation for mobile phone imaging systems. Previously, I conducted a comparative test pitting a professional mirrorless camera costing around five to six thousand (currency unspecified) against a flagship smartphone, with both using automatic mode and no photo parameter adjustments (straight out of camera). The results were surprising: the phone outperformed the professional camera in certain aspects! While the professional camera still held an advantage in depth of field and bokeh, for most users, automatic mode is sufficient for most everyday photography scenarios.

However, automatic mode is not without flaws. The preset color effects offered by phone manufacturers are not to everyone's liking, and in scenes with significant light and shadow variations, automatic mode often fails to capture ideal light and shadow effects. To address this, phone manufacturers are continually upgrading their professional modes, providing users with more freedom and creative control. Many users, however, find the professional mode significantly more difficult to use than automatic mode, deterring them from exploring its capabilities. Many users report the overwhelming complexity of professional mode's features and confusing parameter adjustments. In light of this, I revisited the professional mode on several smartphones, discovering that with the continuous advancements in mobile imaging technology, the functionality and expressiveness of professional mode have been significantly improved, to the point of rivaling a semi-professional camera in certain aspects.

What is Professional Mode in Mobile Photography?

Despite the addition of numerous features to modern professional modes, the core functionality remains largely unchanged. The enhancements primarily focus on adding auxiliary functions to improve efficiency and convenience for professional photographers. Taking my frequently used Xiaomi 15 as an example, its professional mode interface is clean and straightforward, mainly including lens switching and ISO parameter adjustments. By default, parameters are set to automatic mode, providing a user experience almost identical to automatic shooting mode. However, in professional mode, the level of AI algorithm intervention is significantly reduced. The system primarily adjusts shutter speed, ISO, and other parameters based on ambient brightness and color temperature, without excessively altering photo colors. While professional mode may seem complex, the number of parameters requiring adjustment is actually quite limited. Since not all users understand the meaning of each parameter, I will briefly introduce them here:

1. ISO (Sensitivity): Adjusts the camera's sensitivity to light. Higher ISO values result in brighter images but also increase the likelihood of noise.

2. Shutter Speed (S): Controls exposure time, affecting image sharpness and motion blur. Long exposures can achieve special effects, such as flowing water or light painting.

3. White Balance (WB): Adjusts the color temperature of the photo, producing cool or warm tones, and allows manual adjustment to restore the true colors of objects.

4. Autofocus (AF): Adjusts the focus position, creating different depth-of-field effects, such as a sharp foreground and blurred background or vice versa.

5. Aperture (F): Some phones support adjustable aperture, allowing changes to background blur (depth of field) while maintaining the sharpness of the focused object.

6. Focus Peaking: Highlights the areas with the highest contrast, assisting in manual focusing; the clearly marked edges of an object indicate the focus point.

7. Exposure Feedback (Some phones): Real-time indication of overexposed or underexposed areas, helping users understand the exposure of the scene and adjust parameters like ISO accordingly.

To visually demonstrate the effects of these parameters, I have taken several comparative photos:

I recommend readers open their phone's professional mode, experiment with different parameters, and personally experience the changes. However, understanding the function of each parameter is only the first step; the key is to understand how to cleverly utilize these parameters.

How to Use Professional Mode in Mobile Photography?

Although different parameter combinations yield different results, in many cases, precise adjustment of every parameter is unnecessary. For instance, when shooting static portraits in the afternoon sun, primarily adjust ISO and WB, while leaving shutter speed and other parameters in automatic mode.

Professional mode isn't as "professional" as one might imagine. Even beginners can easily create more creative photos by adjusting different parameters. Here's a comparison of photos I took at sunset:

(Insert images comparing automatic and professional mode sunset photos.)

In automatic mode, the sunset, as the main subject, isn't prominent; nearby trees and distant buildings are equally sharp. Automatic mode prioritizes clarity across the entire scene, even when the focus is on the distant sunset, maintaining higher brightness parameters to preserve detail. If one wants a photo with strong light and shadow contrast or vibrant colors, automatic mode falls short.

In professional mode, by manually adjusting only the shutter speed, the light and shadow effects changed significantly. Non-reflective subjects like trees and buildings are subdued, while the distant sunset stands out, and the sky shows greater depth.

When shooting photos with strong light and dark contrasts, ISO and shutter speed are the primary parameters to consider. For example, when shooting a sunset, choose a lower ISO value (100-400) and then adjust the shutter speed until the optimal effect is achieved. Furthermore, if dissatisfied with the photo's tone, professional mode allows easy adjustments to achieve different styles.

Exposure compensation further increases or decreases image exposure, while a wider aperture (smaller f-number) allows the sensor to receive more light, increasing brightness without altering other parameters. However, a wide aperture also causes blurring outside the focus area, so it's not always suitable.

Another often-overlooked point is metering mode a significant advancement in recent mobile phone professional modes. Xiaomi, for example, offers center-weighted, average, and spot metering in its professional mode settings. For sunset photos, I used spot metering, focusing on the sunset to ensure accurate exposure in that area. For a more evenly lit, sharper image, average metering is preferable. Adjusting the metering mode based on specific needs ensures more accurate exposure.

Although smartphones still lag behind professional cameras in hardware, breakthroughs in image algorithms enable high-quality photos in professional mode. Most phones now support RAW format shooting, facilitating further editing on a computer and enhancing post-processing possibilities.

Which Phone Has the Best Professional Mode?

While mobile phone professional modes have improved, advancements in the past year have been relatively minor, leading to a convergence in user experience across different brands. Since automatic mode remains the preferred choice for most users, manufacturers are focusing more on optimizing automatic mode.

For an objective comparison, I tested the professional modes of flagship phones from several major brands, reaching the following conclusions:

Xiaomi, OPPO, and vivo offer comparable ease of use in their professional modes, with function switches easily located.

(Insert images comparing the professional mode interfaces of Xiaomi, OPPO, and vivo.)

Xiaomi places metering, photo format, continuous focus, focus peaking, and other functions in the settings menu, leaving only basic parameter adjustments on the main screen. While adjusting functions requires opening the settings, which is slightly cumbersome, it's easier for beginners to find each function. vivo is very similar to Xiaomi but offers additional professional features such as white balance bracketing, exposure bracketing, Zeiss color, and Zeiss horizon correction. OPPO lags slightly behind; the pull-down settings page only displays simple settings, many options being buried in the jump settings and parameter settings, leading to potential mis-taps or oversight by beginners.

In summary, vivo has invested the most in its professional mode experience, offering superior functionality and usability compared to Xiaomi and OPPO. All three support RAW format for post-processing.

(Insert images comparing the Huawei and Nubia professional mode interfaces.)

Huawei's professional mode, while feature-rich, lacks specific labels for some functions (e.g., metering mode is displayed only as an icon), making it less user-friendly for beginners but offering greater control for professionals.

Nubia's professional mode is impressive, powerful, and easy to use. It provides shortcuts like EFL, AEL, and WBL and offers conveniences for professionals, such as white balance locking. It also includes brightness histogram, RGB merged histogram, and RGB separated histogram for more accurate environmental variable control.

Will AI Redefine Mobile Phone Professional Mode?

With the proliferation of AI algorithms, manufacturers focus on professional mode has somewhat diminished. However, I believe that if automatic mode represents the lower limit of mobile phone imaging performance, professional mode represents the upper limit. AI algorithms can ensure photos are "beautiful," but they struggle to capture the "soul" of a photograph.

While professional mode offers many advantages, the user experience for average users is not ideal. Users willing to invest time in adjusting parameters and learning photography techniques (The sentence is incomplete in the original text)
