Seattle is known more for its clouds than its sunny days, so when the sky is blue, the bright light can feel harsh. Here, the S25 Ultra photo pops more by lightening the shadow areas of the car, but almost too much. The Pixel 10 Pro XL image looks more natural, even though the car is darker.

Just down the street, though, the contrast between the cameras swings in the other direction. The Pixel 10 Pro XL brings out all the vibrant colors of the flowers, the orange awnings and the bright red umbrellas. The S25 Ultra’s shot is more muted. I couldn’t tell if perhaps some of the sunlight was hitting the lens from the side and causing that washed-out appearance. Both cameras still did a fine job of keeping details in the shadows, though.

Pixel 10 Pro XL vs. Galaxy S25 Ultra: Zoom quality

To be honest, zooming much past 10x on a phone always seemed like a futile gesture to me. Pushing past the optical range of the telephoto camera (5x on both cameras) puts you into digital zooming territory, where the camera upscales a small portion of the sensor so it fills the frame. Although digital upscaling has improved in recent years, when you get past 20x or so, photos tend to become a mess of fuzzy enlarged pixels — it’s rarely worth it.

Google decided to take a different approach to extreme zooming on the Pixel 10 Pro and Pro XL. Up to 30x zoom, it uses Google’s Super Res Zoom technology to upscale and sharpen the results, which generally turn out well.

In the extreme range from 30x to 100x, though, the Pixel 10 Pro uses generative AI to rebuild the image based on the original capture. It takes a few seconds for the processing to happen, and it’s all done on-device, not with assistance from cloud resources. The results can be impressive, particularly for static subjects like buildings or landscapes. But when you view them with any scrutiny, it’s almost always obvious that the photo has been treated with AI, with a flat, angular look — and it doesn’t handle most text in a photo at all. But that’s also me scrutinizing the image; it won’t look good printed or viewed on a large screen, but it comes across perfectly fine on a phone screen.

The Pixel 10 Pro keeps both versions of the image: The original capture and the AI-generated one.

Google says that if the camera detects people in a Pro Res Zoom image, it won’t attempt to use generative AI on them — it could easily create a person that looks nothing like the actual person in the image. When that happens, you can tell: In this shot, the sailboat has been rendered (complete with a nonsensical guess about lettering on the sail), but the people on board are sharpened but still fuzzy.

The Galaxy S25 Ultra shots at 100x are also a hot mess, but to be honest, not as bad as I expected. They’re heavily processed to compensate for the upscaling, but… not terrible? I feel like I’m giving the S25 Ultra a “good job, buddy!” for showing up and not face-planting when, in fact, the photos are objectively not great, but they’re better than I expected.

Pixel 10 Pro XL vs. Galaxy S25 Ultra: Low-light situations

Pike Place Market is a maze of levels and long, shop-lined corridors and alleys that don’t get a lot of direct light. The notorious Gum Wall — yes, an alleyway where people stick used gum on the brick walls — is dark at one end and brighter at the other depending on the sun’s position in the sky. Neither phone fell back into its respective night mode, and both made acceptable shots in the midst of a lot of color and texture. Here again, I give the edge to the Pixel 10 Pro XL for its warmth and brighter overall tone. However, in both shots, the details on the wall suffer — note the pixelated “Extra” wrapper at top left. My apologies if you’ve just lost your appetite; at least photos don’t include the specific aroma of an alley filled with thousands of fruity gum globs.

Speaking of colors and textures, this barbershop in a muted hallway lit by what look to be fluorescent ceiling bulbs and a prominent ring light is another example of each camera taking a mixed-light situation and making a good exposure. I give the edge to the Pixel 10 Pro because the neon Open sign hasn’t been turned into a flat red, as in the S25 Ultra photo.

Leaving the bustle of downtown Seattle for the beach near the Mukilteo Lighthouse about half an hour north, this beach at sunset looks much better using the ultrawide camera on the Pixel 10 Pro XL compared with the ultrawide on the S25 Ultra. And in this case, I can’t say that either picture impresses. The S25 Ultra shot is almost too dark, while the Pixel 10 Pro XL image is too bright, and the bro on the edge doesn’t survive the wide-angle edge of the frame too well.

And for a true night test, I put both phones on a tripod to capture this section of Shilshole Marina. Once more, the Pixel 10 Pro XL’s Night Sight mode does a better job of getting a balanced exposure that mixes the artificial lights in the foreground and the darkness of the sky with some stars peeking through. The S25 Ultra looks like it’s throwing as much processing at the image as possible, making the brighter areas look overexposed and introducing a lot of noise in the sky.

Pixel 10 Pro XL vs. Galaxy S25 Ultra: Portrait modes

One of the improvements Google is touting for the Pixel 10 Pro is in the quality of portrait mode photos, specifically high-res 50-megapixel shots.

In this indoor cafe with screened window light, the Pixel 10 Pro XL is really trying to contain the flyaway wisps of hair, but it’s made them ghostly and more evident instead. Everything else about the photo looks good, from the colors to the soft background — in fact, the hair at her shoulders shows better separation than on top of her head.

On the other hand, the S25 Ultra’s Portrait mode photo has made the top hairs nicely distinct, but the falloff at her shoulders and the general smudge of background make the depth of field in this photo more obviously synthetic. Also, once again, I prefer the tone and warmer temperature of the Pixel photo.

Outside, the S25 Ultra’s Portrait mode is improved, with more natural blurred areas — note the hair over the subject’s left shoulder that’s slightly blurry but not as soft as the foliage in the background. The flyaway hairs at the top of their head also look natural. The high-resolution Portrait mode version from the Pixel 10 Pro looks entirely natural to my eye, with a soft background and all of their curly hair in focus. Once again, I prefer the Pixel’s version, but they both look good. (Although I probably should have tried Camera Coach to compose the portraits better in the frame without so much space above their head.)

Pixel 10 Pro XL vs. Galaxy S25 Ultra: Which is the better camera?

I’ve certainly come down on the side of the Pixel 10 Pro XL for most of these photos, largely due to the warmer white balance and better color fidelity. But as you can see, none of the photos are outright bad. If you’re looking for a new flagship Android phone, both models will fill that need. And if you specifically want a great camera system, right now the Pixel 10 Pro has pushed into the lead.
