Smartphone cameras and the software that automatically processes the images have become so good at creating fantastic photos on the fly that most people don’t even carry a separate camera anymore (well, except for some Gen Zers going retro). There are plenty of apps that can slap a filter on a picture to make it look even better, but if you really want to elevate your mobile photography skills, consider the format the pros use: RAW.
Editing a RAW file is more work, but it allows the photographer to have more control of the light and color in the image after it’s been captured — and in some cases, enough pixels to significantly crop the photo and still have it look sharp. Here’s a guide to getting started.
What Is RAW?
“RAW” means raw data — and lots of it. Many phone cameras automatically capture and save images as JPEG or HEIC files, which crunch down and discard some of the image data to reduce the file size. However, when you choose to capture images as RAW files, you get uncompressed and unprocessed data from the camera’s sensor. Without the compression, RAW images contain more detail and colors to work with. But the files can be huge.
There are many specialized camera tools that capture and edit RAW files available in the app stores. (More on those later.) But if you’re just dabbling for now, here’s how to use the options available on the newest iPhone and Android models, as well as other free tools.
The iPhone’s RAW settings
On an iPhone 12 Pro (or later Pro and Pro Max models) running at least the iOS 14.3 operating system, you can capture and store RAW files by going to the main Settings app, and choosing Camera and then Formats. Tap the button next to Apple ProRAW, which is Apple’s variation on the RAW format. On iPhone 14 Pro models, you can choose the resolution to store your RAW files: 12 megapixels or a whopping 48 megapixels.
Then open the iOS Camera app, line up the shot and choose the RAW feature at the top right of the screen. Now all you have to do is tap on the shutter button to save the file to the camera roll.
A 48-megapixel file allows for photos with good detail even with significant cropping, but the file size of each photo can be 75 megabytes or larger. If you have an iPhone with a terabyte of space, the larger file sizes are less of a problem, but phones with less storage can run out of space fast.
Only images taken with the iPhone’s main camera can be saved at the 48-megapixel resolution. Those snapped with the phone’s wide-angle or telephoto cameras (or photos captured in night mode or with a flash) are automatically saved at the 12-megapixel resolution.
RAW options for Android
Finding the RAW settings on an Android phone varies based on the device and its manufacturer, so check your phone’s support site for specific instructions.
If you have one of Google’s Pixel phones running Android 13, go to the Camera app and tap the Down arrow in the upper-left corner, then choose More Settings and then Advanced. Next, tap the button next to RAW + JPEG control. The camera will capture the image in both JPEG and RAW formats, but it saves the larger files into a separate RAW folder on the Google Photos app.
On Samsung’s Galaxy phones, the Camera settings includes a Pro mode and advanced picture options to save images as RAW files. In the settings, go to “Format and advanced options” and tap the button for RAW copies. For late-model Galaxy phones, Samsung also recently released its free Expert RAW camera app, which is available in the Galaxy Store.
Edit your RAW files
If you have an iPhone, you can use Apple’s Photo app to edit RAW files. For Android phones, Google Photos offers “limited” support for the format, but its older photo-editing app, Snapseed, has a tool to edit RAW files. The Snapseed app, which is free and works on both Android and iOS, has a support site with an online tutorial and an instructional video on YouTube for beginners.
At first glance, RAW files can seem flat, murky and bulky. But once you start to process them in a compatible photo-editing program, you can take advantage of all that extra data.
In the editing app, you can use the on-screen slider and other controls to adjust an image’s white balance, which neutralizes color casts; change the exposure; pull parts of the picture out of shadows; deepen colors and more.
Some photographers prefer to handle RAW files using tools in Adobe Lightroom, which have mobile versions for Android, iPhone and iPad devices (free, with in-app purchases). Adobe’s site has a tutorial, as do many websites specializing in digital photography.
To edit your photos on a bigger screen, you can store the files in a cloud server or transfer the file from your mobile device to a desktop computer using Wi-Fi or AirDrop, and then use either Adobe Lightroom’s subscription desktop version or one of the many desktop photo apps (including Apple’s Photos for Mac).
Once you are ready for more advanced techniques using RAW files, you can buy or subscribe to the myriad specialized photography apps in your app store, including VSCO (for Android and iOS) and ON1 Photo RAW (also for Android and iOS). For those using iPhones and iPads for editing, you could also consider the apps Halide Mark II, Darkroom and RAW Power.
When you’re done editing your RAW image, you can save it as a JPEG or other common formats for sharing, printing or making art.
