You can get great images straight from the iPhone and iPad's stock Camera app and share them with your friends and family. But if you're interested in using your iPhone for more pro-level photography experiments, there's a new tool for you in iOS 10: shooting RAW.you can now shoot in the RAW file format and get even more out of your images.

So... what exactly is RAW?

RAW is a file format that contains the raw data directly from a camera sensor. This raw data is unprocessed and uncompressed; it's the "purest" form of the image. RAW files tend to appear quite flat in coloration and depth initially as a result, but it allows users to really bring them to life in post-production.

RAW files tend to be larger than JPEGs: This is because JPEG files are compressed, while RAW files are not. As a result, RAW can record significantly more dynamic range, which is vital when it comes to editing.

When you shoot RAW, you can pull down highlights or boost shadows to bring out new detail in the image. It's a huge win for photographing high-contrast scenes, and it's why most professional photographers generally opt to shoot RAW. 

Let's see some JPGs and RWAs pictures ,you will know what I have said :

How to shoot RAW images on your iPhone or iPad？

Different camera makers use different varieties of RAW file formats (Canon uses .CR2 and Nikon uses .NEF, for example). An increasingly common RAW standard, however, is Adobe's .DNG (Digital Negative); this is the format Apple has chosen for iOS 10.What's especially interesting about iOS 10 and RAW is that Apple hasn't adopted it for its built-in Camera app — the company is instead leaving it up to third-party developers to implement.

As with Apple's manual camera controls, you can only shoot RAW in third-party apps that support the feature. Some of our favorites include Obscura, Manual, and ProCamera, but you can check out all our recommended manual camera apps for more options.To shoot RAW, choose the camera app of your choice and look for its RAW controls.
