How to shoot RAW photos with your compatible iOS 10-running iPhone

Simply put, RAW images are lossless files that contain uncompressed and minimally-processed data captured from the camera sensor of the device. That's usually the format Also known as "digital negatives", said files need to be developed with additional software, like Adobe Photoshop Lightroom, Apple Photos, Corel AfterShot, etc. We wouldn't delve further into this issue for further reading check Wikipedia or look around on Google. 

What are the benefits of RAW versus JPEG?

Countless, but we will narrow it to a couple of things.

First of all, the lack of compression means that if you export a JPEG or a PNG file out of your source RAW, there will be zero loss of detail in comparison with a regular JPEG photo taken with the camera in the same situation. Essentially, you get the highest level of quality you can eke out of your phone's sensor. 

Also, RAW files usually have a bit depth of 12, 14, or16 bits compared with the measly 8-bit depth of a run-of-the-mill JPEG file. This means that RAW files retain a way larger amount of different brightness levels that you can edit without compromising the overall image quality - an 8-bit JPEG gives you 256 levels to play around with, while a 12-bit RAW gets you 4096. This lets you fine tune the shadows and the highlights and correctly expose your photo. 

RAW also lets you correct severely over- or under-exposed photos without deteriorating the overall quality of your photo thanks to the larger amount of information it holds within itself. Additionally, when you're shooting in JPEG your phone automatically sets the white balance of the image; with RAW, you can set the white balance afterwards in a non-destructive way.

We can go on, but what you need to take home at the end of the day is that  RAW is a much, much better choice if you want to produce quality images. With a bit of manual post-processing and touching-up, a RAW file can easily blow a JPEG pic out of the water. 

Now, many will be quick to argue that one can also edit JPEG image to achieve similar results. While that is mostly true, we shouldn't overlook the fact that unlike RAW, compressed JPEG images are way less forgiving when it comes to subsequent editing. 

Let's talk examples now. We took a resident iPhone 6s Plus, downloaded Manual (a camera app that supports RAW), and went out for a walk. We shot some regular JPEGs with the default iOS camera app and shot the RAWs with Manual.

The rather bleak and over-exposed JPEG is absolutely nothing to write home about and would normally find its final resting place in our recycle bins: the colors are uninspiring and the foliage in the background. After a few basic edits in Adobe Lightroom, we achieve a much better look for our flower scene.

The JPEG in the tricky scene above has preserved zero to no detail in the sky and clouds' area. Everything is a milky blur; the colors of the sky-blue car are also a bit off and appear a bit greenish. RAW to the rescue - we snapped two identical pictures with different expositions, merged them together into an HDR image and after a few touch-ups,  we've got a way better-exposed picture with more vivid colors.

This otherwise great shot would have been ruined if we went with the JPEG, which is obviously uninspiring and rather dull - it looks like someone has put a brown filter in front of our lens, yuck! Once again, RAW saves the day - after combining two images into an HDR in order to preserve as much detail in the sky area as humanly possible, we edited the image to the point where it's essentially wallpaper-worthy.

Once again, under low-light outdoor conditions, a run of the mill JPEG photo will end up mostly unimpressive. It takes a RAW image file to bring out the best of that beautiful flower and the industrious bee sucking its juices.

The JPEG in this scene clearly shows us why you should consider shooting RAW in tricky situations. In this indoor scenario, the JPEG exhibits a totally wrong white balance, making white appear yellowish, greens have a noticeable blue tint, while detail on the tiny plant in the background is hard to discern. That's not we are looking for in a photo. On the other hand, after a few basic edits, the RAW image we developed has more details preserved as well as the correct white balance for that scene. Also, the Android figurine is the correct hue of green.

Yes, but you need to make sure that you're sporting a compatible model. Currently, five iPhones and one iPad can shoot RAW photos: the iPhone SE, the iPhone 6s, the iPhone 6s Plus, the iPhone 7, the iPhone 7 Plus, and finally, the 9.7-inch iPad Pro. The common denominator between all of these is that they all sport 12MP iSight cameras at the back. If you have one of these and you're running iOS 10, you're good to go. Oh, and have in mind that only the rear camera can shoot RAW images.

Well, have in mind that due to their lossless nature, RAW files are noticeably larger than compressed JPEGs. DNG files taken with your iPhone will generally vary in size but will gravitate in the 9–11MB range, whereas a high-quality JPEG images are at around 3x - 4x smaller. Thus, enabling JPEG + RAW capture from within a compatible third-party app and snapping a ton of pictures will take up lots of your phone's storage, so have this in mind. 

All right, seems you've decided to improve your photography game big time, congrats! As we mentioned multiple times, you need to pick a camera app from the App Store that has this new feature implemented by its developer. Examples of such apps are Adobe Lightroom, Manual, ProCam 4, ProCamera, and many others. We will explore these in a separate post for the sake of brevity - you can check it out here.
