Hey everyone, which multi-lens camera setups do you prefer? I'm curious about your take on 3-camera vs. 4-camera systems, sensor sizes, and so on. How do you usually approach these choices? For example, when merging ultra-wide shots with the main camera's footage, what do you focus on? Or, in low-light mode, what methods do you use to make the sensors support each other? In practice, what should we prioritize, and which factors do you think are most important?
How should we approach Oppo-style camera systems?

When I had an Oppo device with four cameras, I used the ultra-wide-angle lens essentially as a "secondary assistant"—not to complement the main lens's 70% FOV, but to provide "more sky/ground area" in wide landscape shots. The stitching process is handled by Oppo's "[Hasselblad Natural Color Calibration](https://www.oppo.com/en/newsroom/oppo-find-x7-ultra-features-hasselblad/)" color profile. For night mode, instead of "binning," they use a "different exposure time + shared light collection" method (the main sensor takes a 1/2s shot while the others take 1s exposures to balance noise). In practice, it's not so much about sensor size but the "amount of lens overlap"—because this determines the quality of the images entering the software layer.
