The jump from the iPhone 6s to the iPhone 11 represents more than just a generational shift—it’s a leap in mobile photography. Released in 2015, the iPhone 6s was praised for its 12MP rear camera at the time, but by 2019 standards, it showed its age. The iPhone 11, launched four years later, brought significant upgrades not only in hardware but also in computational photography. For users considering an upgrade or curious about how far Apple has come, the question remains: did the camera upgrade make a huge difference?
The short answer is yes—dramatically so. But the full picture involves more than megapixels. It's about image processing, dynamic range, low-light performance, software enhancements, and video capabilities. Let’s break down exactly where the improvements lie and what they mean in real-world use.
Sensor and Hardware Evolution
The iPhone 6s features a single 12-megapixel rear camera with an f/2.2 aperture, optical image stabilization (OIS), and phase-detection autofocus. While solid for its era, it lacks advanced features like portrait mode, night mode, or ultra-wide shooting. Its front-facing camera is 5MP with Retina Flash—an improvement over previous models but limited in low-light detail.
In contrast, the iPhone 11 introduced a dual-camera system: a 12MP wide lens (f/1.8) and a 12MP ultra-wide lens (f/2.4). The wider aperture on the main sensor allows more light capture, improving low-light shots. The inclusion of the ultra-wide lens expands creative possibilities, letting users capture landscapes, architecture, or group photos with significantly more context.
Apple also upgraded the image signal processor and integrated the Neural Engine into the A13 Bionic chip, enabling smarter scene recognition, better HDR processing, and real-time depth mapping for portrait effects.

Image Quality: Daylight and Dynamic Range
In well-lit conditions, both phones can produce acceptable images, but the differences become immediately apparent upon close inspection. The iPhone 11 captures richer colors, deeper contrast, and superior dynamic range thanks to Smart HDR, which intelligently balances highlights and shadows.
The iPhone 6s tends to overexpose bright skies or underexpose subjects in backlit scenes. It lacks local tone mapping, meaning details in shadows are often lost. The iPhone 11, however, uses machine learning to analyze different areas of the frame separately, preserving detail in both dark and bright regions.
Low-Light Performance: Night Mode Makes a Difference
This is where the gap widens most dramatically. The iPhone 6s has no dedicated low-light enhancement. In dim environments, photos become noisy, blurry (due to slower shutter speeds), and lose color accuracy.
The iPhone 11 introduced Night Mode—a game-changer. Automatically activating in low light, it combines multiple long-exposure frames to reduce noise and boost brightness while maintaining natural color tones. Even without flash, the iPhone 11 produces usable, detailed images in near-darkness—something the 6s simply cannot match.
For example, taking a photo indoors without additional lighting: the 6s might produce a grainy, orange-tinted image with motion blur. The 11 delivers a clean, balanced shot with accurate whites and minimal noise.
Video Capabilities: From HD to 4K at 60fps
Video recording saw one of the most practical upgrades. The iPhone 6s supports 1080p HD video at 30fps and slo-mo at 120fps. While adequate for casual use, it lacks stabilization in higher frame rates and doesn’t support 4K.
The iPhone 11 records 4K video at up to 60fps, includes extended dynamic range for video (up to 60fps), and features cinematic-grade stabilization across all cameras. Audio zoom syncs directional sound with optical zoom, enhancing vlogging and storytelling.
Additionally, the front camera on the iPhone 11 shoots 4K video and supports slow-motion (1080p at 120fps), making selfies and face-to-camera content significantly sharper and more professional.
| Feature | iPhone 6s | iPhone 11 |
|---|---|---|
| Rear Camera Resolution | 12MP | 12MP (Dual: Wide + Ultra-Wide) |
| Aperture (Main) | f/2.2 | f/1.8 |
| Low-Light Mode | No | Night Mode (Auto) |
| Portrait Mode | No | Yes (Rear & Front) |
| Video Recording | 1080p @ 30fps | 4K @ 60fps |
| Front Camera | 5MP | 12MP, 4K video, Slofies |
| Smart HDR | No | Yes |
Real-World Example: Travel Photography Upgrade
Consider Sarah, a frequent traveler who used her iPhone 6s for documenting trips across Europe. She loved capturing street scenes and sunsets but often found her photos disappointing—overexposed skies, muddy shadows, and poor indoor shots in museums or cafes. After upgrading to the iPhone 11, she noticed immediate improvements.
During a visit to Paris at dusk, she took a photo of the Eiffel Tower lit against a twilight sky. On the 6s, the tower would be washed out, and the sky turned gray. With the iPhone 11, Night Mode activated automatically, producing a vibrant image with crisp lights and a deep blue gradient in the sky. Later, inside Notre-Dame, where lighting was dim and uneven, the 11 captured clear textures in stone carvings—details lost entirely on the 6s.
She also began using the ultra-wide lens for capturing entire facades of buildings without stepping back—something previously impossible without cropping or stitching.
Actionable Checklist: Is Upgrading Worth It?
If you're still using an iPhone 6s and wondering whether the camera upgrade justifies the cost, consider this checklist:
- Do you frequently take photos in low light? → iPhone 11 adds Night Mode
- Do you want sharper, more detailed selfies? → 11 has 12MP front camera vs 5MP
- Are you frustrated by overexposed skies or dark shadows? → Smart HDR fixes exposure imbalances
- Do you record videos regularly? → 4K at 60fps offers professional-grade quality
- Do you wish you could capture more in a single shot? → Ultra-wide lens expands field of view by 120°
- Do you use Portrait Mode? → Available on 11 (not on 6s)
If three or more apply, the upgrade brings meaningful benefits.
Frequently Asked Questions
Can the iPhone 11 take better portraits than the iPhone 6s?
Absolutely. The iPhone 11 supports Portrait Mode on both front and rear cameras, using depth mapping from the dual-lens system and machine learning. The 6s lacks hardware and software support for true depth effects, making any “portrait” look artificially blurred and less realistic.
Is the front camera really that much better?
Yes. The jump from 5MP to 12MP is substantial. The iPhone 11’s front camera captures four times more detail, supports 4K video, and introduces “Slofies”—slow-motion selfies. Combined with Retina Flash and improved skin tone rendering, selfie quality improves dramatically.
Does software matter as much as hardware?
More than ever. While the physical sensors are better, Apple’s computational photography—Smart HDR, Deep Fusion, Night Mode—is powered by the A13 chip and years of algorithm refinement. Two phones with similar megapixels can perform very differently based on software alone. In this case, both hardware and software leap ahead.
Conclusion: A Transformative Upgrade
Moving from the iPhone 6s to the iPhone 11 isn’t just an upgrade—it’s a transformation in how you capture and experience photography. The camera improvements aren’t subtle tweaks; they represent fundamental advances in low-light capability, dynamic range, video resolution, and creative flexibility.
If your iPhone 6s is your daily driver, know that today’s smartphones don’t just take pictures—they enhance them intelligently, preserve moments more faithfully, and empower creativity without extra gear. The iPhone 11 delivers all of this out of the box.
