It’s all smoke and mirrors. But you can call them “options” and “settings”.
48 megapixels. This is the maximum image resolution an iPhone 14 Pro user can achieve from the wide-angle camera. That’s a 65% increase in image resolution, about the same as some medium format cameras. But the iPhone camera can also capture 12MP stills of him. What are the reasons for the disparity?
Well, there’s a lot to unpack. We start with the camera array.
all good things come in three
The iPhone 14 Pro rear camera array has three cameras. First, there’s a 12MP ultra-wide-angle 13mm camera with a ƒ/2.2 aperture and a 6-element lens. For long range shooting there is a 12MP 77mm 3x telephoto lens with ƒ/2.8 aperture, optical image stabilization and a 6-element lens. Finally, the main 24mm ƒ/1.78 aperture camera features 2nd generation sensor-shift optical image stabilization and 7 lenses.
This is a very complex technology packed into a bounding box about 1 inch on each side. But something interesting happens on the software side.
4 to 1 advantage
The iPhone 14 Pro’s camera sensor relies on something called “pixel binning,” a process of combining pixels and averaging their values. This allows high-megapixel sensors to output lower resolutions to reduce noise and improve frame rates. This concept is used in the iPhone’s main 24mm camera and is called the Quad-Pixel Arrangement, an Apple-branded version.
It allows users to shoot RAW images and combine 4 pixels into one super pixel with 2.44 microns real estate to capture 12MP images with excellent low light capabilities. Alternatively, you can use each pixel individually to create a larger, more detailed 48MP image of him. This allows content he creators not only to have high-quality images, but also options.
The user[設定]in the menu[カメラ],[フォーマット], then toggle the Apple ProRaw option to enable Apple ProRaw. This turns off Quad-Pixel Arrangement and saves the image in uncompressed 48MP ProRaw format.
ProRaw is also available in 12MP lossless configurations by selecting that option in the ProRaw resolution settings and turning on Quad-Pixel Arrangement. This feature groups pixels into dedicated red, green, and blue clusters, and the camera uses computational photography and machine learning to build the image into the best possible presentation.
Apple calls this process “deep fusion,” and puts a special “photonic engine” processor in an Apple silicon SOC (System on a Chip) to do the heavy lifting. Deep Fusion takes uncompressed RAW image data from up to 12 photos and combines them to produce 10-bit and 12-bit color gamuts with up to 68 billion shades.
We also see a 2x improvement on the wide camera and a 2.5x improvement on the primary camera. The iPhone camera may look impressive, but a lot of the work is done at the software level.
Shooting in 48MP mode allows you to crop, reframe and zoom high resolution images without losing as much detail as you normally would. This is very useful for producing these two camera angles in one image by cropping. The 48MP camera also improves sky contrast and provides more detail in background images.
However, this results in much larger image file sizes, which can be a problem if creatives buy the 128 GB model.Images shot at 48MP resolution can be over 100MB in size. . Add in his 4K ProRes HDR video at up to 60 frames per second with Apple’s new Cinematic and Action mode stabilization, and you have a mobile filmmaking tool that quickly consumes that 128 GB of his. increase.
But creators are starting to make incredible-looking footage and spend money on dedicated cameras.
better in low light
Conversely, Quad-Pixel Arrangement mode allows the camera to allocate 4x the light-gathering capacity to each pixel bundle, even for 12MP images, resulting in better low-light performance. In low light, Apple has improved performance, albeit at the cost of some detail. But Apple does its best to mitigate this with its large aperture lens and quad pixel arrangement. Shooting in 12MP Pro-Raw is also beneficial. As with all photos and videos, you have to make sacrifices.
In short, ProRaw gives you greater creative freedom. A handy tool to have in your pocket for content creators and mobile filmmakers. literally.
Hopefully, as Quad-Pixel Arrangement technology matures, Apple engineers can find a way to make it all available to content creators. and low-light options to give users the boost they need.
