iPhone 5′s back-facing camera has the same 8-megapixel, five-element lens with 2.4 aperture as the iPhone 4S. It is also 25% smaller and has the same 3,264 by 2,448 backside-illuminated sensor, but comes with improvements such as 40% faster photo capture, improved low-light performance, and improved noise reduction.
The native Camera app and third-party camera apps take advantage of iPhone 5′s low-light boost mode. If you’re familiar with camera terms then it means that iPhone 5′s camera ISO can go up to 3200 (vs 800 before – that’s four times the power). ISO is the measurement of a camera’s sensitivity to light. The higher the ISO number the more sensitive the sensor is. A higher ISO number means that a camera will be able to shoot images in conditions with less light. Simply put, it just means that you can take photos with less light than ever before.
Strangely, the native camera app doesn’t make use of the low-light boost mode while taking Panorama mode. It’s not clear if there is a reason for not using the mode while taking panoramic photos, but if you want to enable it then it is now possible thanks to a new jailbreak tweak called LLBPano. It’s by @Poomsmart, the same developer who had released a jailbreak tweak called LLBiPT5, which enables low-light boost mode in iPod touch and Flashorama, which lets you turn on LED flash while taking panoramic photos.
You can enable or disable the low-light boost mode in the Settings app (Settings -> LLBPano -> Panorama Low-light mode toggle).
I tried it out on my jailbroken iPhone 5 and noticed an improvement in the quality of panoramic photo in low light.
LLBPano is available for free on Cydia. There have been some complaints about it causing boot loop problems, but the developer has fixed it in the latest update (v1.0-2). If you’re on your iPhone 5, tap on the download link below to install it from Cydia. Please note iPhone 4S, iPhone 4 or iPhone 3GS are not supported. According to the developer, iPod touch 5G is supported but need to install the LLBiPT5, not sure how it works since it doesn’t have the necessary hardware to support it.
Let me know how it goes in the comments.
