iOS 9.3 is coming in the Spring and will introduce Night Shift as well as a number of other new features.
A Look at iPhone 4's Camera Quality
As part of its feature page on the new camera, Apple has posted several example photos, noting that they are actual, unretouched photos taken using the iPhone 4. The images show clear, high-quality photos taken under optimal light conditions. Gizmodo took a look at the metadata included on one of the photos and offered its perspective on the image quality.
The performance under obviously optimal light is very good. The processing leans a bit to over-saturation and over-exposure, which is not a bad thing. Nikon goes for a similar image processing treatment in their cameras.
However, keep in mind that this image doesn't confirm Apple's claims about higher ISO and better performance under low light conditions, which is supposed to be a lot better thanks to the bigger backlit sensor. We will have to wait to see this in our review.
And besides the still image features, iPhone 4's rear camera is also capable of HD video recording in 720p at 30 frames per second. With tap to focus, LED flash for video, and iMovie for iPhone for editing footage, Apple touts the new iPhone's ability to shoot, edit, and share high-quality video all on a phone with no need for access to a computer.
