What does Apple's raw photo mean?

Raw in Apple camera means that the pictures taken after using Apple mobile phone to turn on the raw mode will be saved in unprocessed format, and the color information of the pictures will be reserved for post-processing. Its raw format is an unprocessed format, which is no stranger to many photographers.

RAW is a lossless format, which retains richer levels and details, has wider adjustment space, and the adjusted image will not lose data.

Correspondingly, JPEG format compressed from RAW stores less details of color information, and its later adjustment range is limited. However, the RAW format needs to be opened with a corresponding camera or professional application, and its compatibility and universality are not as strong as JPEG format. RAW format is more suitable for experienced photographers who need post-optimization of photos, while JPEG format is more suitable for direct users who don't need post-optimization.

Apple ProRAW, which appears on the iPhone 12 Pro series, can be understood as having the control and flexibility of the traditional RAW format, and at the same time, it allows photographers to experience the power of Apple in computational photography. By establishing a new image pipeline, Apple merged the processing of CPU, graphics processor, image signal processor and neural network engine into a new depth image file.

Apple ProRAW also integrates the advantages of multi-frame processing and computational photography, such as the existing DeepFusion technology and intelligent HDR 3, and all front and rear cameras are available. All the algorithms behind these will end when you finish shooting, and there is no shutter delay. Apple ProRAW also adds Apple's noise reduction processing, so that you can take the lead in the later stage and have more time to deal with other aspects.
