Speaking of noise, the default 12-megapixel images were often surprisingly noisy even when shooting in broad daylight at the lowest ISO. The noise won't be visible when looking at the images on your phone's screen but would become noticeable if you start editing the images or if crop into it. In comparison, the OnePlus 8 Pro images had surprisingly low noise, despite having similar or even greater detail. The higher sharpening on the OnePlus 9 Pro also doesn't do it any favors as the noise in the images also tends to get accentuated by it.
The color performance is also a mixed bag. We had high hopes in this area, especially since OnePlus promised more natural color reproduction, but the OnePlus 9 Pro images aren't exactly natural. Daylight images can often have deeply saturated skies and bold green foliage, which is much more vibrant than in the actual scene. The white balance has a tendency to be on the cooler side while shooting in sunny conditions. Reds will occasionally shift towards magenta, especially in indoor lighting. The contrast also tends to be jacked up significantly at times, often to the detriment of the image.
Compared to its predecessor, the OnePlus 9 Pro occasionally performed worse. The OnePlus 8 Pro often had a more correct white balance and more balanced, less contrasty images.
Dynamic range is average. While the OnePlus 8 Pro had a tendency to overexpose, the OnePlus 9 Pro tends to underexpose, which can cause images to have less detail in the shadows. OnePlus' UltraShot HDR can still have that fake, aggressive tone-mapped HDR look to it at times, especially when shooting indoors, and the images from auto mode don't look as natural as those from Apple or Google smartphones.
The actual sensor on the OnePlus 9 Pro is leagues ahead of its predecessor. The IMX789 handily outperforms the IMX689 in dynamic range and low light performance. Trying to compare RAW images captured on both phones, the files on the OnePlus 9 Pro can be pushed much further in post and shadows remain clean even after +3 exposure thanks to the dual native ISO whereas the OnePlus 8 Pro images start falling apart when pushed similarly. The level of detail in the RAW files is also impressive.
It's clear then that the issue lies with OnePlus - and now Hasselblad's - tuning of the default JPEGs. If you don't mind getting your hands dirty, you can get so much more value out of this camera by shooting in RAW and processing the images yourself as the actual hardware in here is absolutely top-notch. Even the JPEG files from the Pro mode are generally superior to Auto mode, as they have less sharpening, noise, and more natural contrast.
The new ultra-wide camera on the OnePlus 9 Pro is impressive, as far as ultra-wide cameras go. The color performance is similar to the main camera but despite the incredibly wide perspective, the level of detail from the 12.5-megapixel images is really quite good.
But the main attraction here is the new freeform lens. On most other smartphones, the ultra-wide image needs to be corrected in software to remove the distortion around the edges. This is usually enabled through the camera settings and the reason this is optional is because enabling it crops the image, which reduces some of the wide perspective. This is how it's done on the OnePlus 8 Pro as well. On the OnePlus 9 Pro, there is no such option in the camera settings because the freeform lens corrects the perspective before the image even hits the sensor.
This results in images that are wider than on the previous generation model without any distortion. It's actually pretty cool and straight lines even around the edges of the frame continue to be straight without bending.
自动模式确实翻车了，白天色彩表现还不如8pro...不过789本身确实比689素质强很多，用专业模式的jpg或者raw效果更好。拍视频的话，只有4k120无裁切，超广角8k是假的，其他模式 eis无法关闭会裁切大量画幅。

苹果这代HDR搞得确实太艳了，我看着都想吐
