You can edit photos in a variety of formats with the macOS Photos app. For some folks, working with the RAW format offers several benefits.
RAW vs JPEG.
Of course, keep in mind that files in the JPEG format, the standard file format in the digital photography world, are stored as compressed files. This means they take up less storage space than RAW files.
Unlike a JPEG file, RAW format is uncompressed and isn’t actually an image file, but is a collection of data from your camera’s sensor that are saved on your camera. Software like Photos allows you to view the data as images and edit the RAW files. The benefits — as noted by Format magazine are:
- Your camera is capturing absolutely all the data it receives from the camera’s sensor so you have more data to work with.
- RAW has a higher brightness level than JPEG.
- The RAW format contains 68 billion more colors than JPEG files.
- RAW files have a higher dynamic range than JPEG files.

The best way you can use the RAW format is after you’re done shooting, during the editing process. Which is where Apple’s Photos comes in.
About RAW Files on a Mac
There are some things you should know about the availability of RAW files on your Mac depends on a few conditions:
- If you have the Download Originals to this Mac option turned on in Photos (Photos > Preferences > iCloud > Download Originals to this Mac), then your RAW files are always present in Photos on your Mac.
- If you have the Optimize Mac Storage option turned on, then your RAW files are stored in iCloud Photos. The Photos app saves disk space on your Mac by displaying optimized JPEG versions of your RAW images. If you edit an optimized image on your Mac, Photos downloads the RAW file for that image.
- When Photos downloads a RAW image from iCloud Photos, it creates a new full-sized JPEG for optimal viewing on your Mac. It won’t replace the RAW and embedded JPEG file already stored in iCloud. iOS devices will view the embedded JPEG.
- RAW files that you store outside the Photos app library (say, in your Pictures folder) are always present on your Mac, but aren’t stored in iCloud and won’t stay up to date in the Photos app on your iPhone, iPad, or iPod touch.
How to Import RAW Image Files Into Photos
To import RAW image files into Photos, open the app and:
- Select File > Import.
- Go to the folder containing the files you want to import as RAW.
- Select a file or files and click Import.
- In the Import view, select the images to keep, then click Import Selected.
Use a RAW File as the Original in Photos
Some cameras allow you to shoot photos in both RAW and JPEG formats simultaneously. When you import your pics from these cameras, Photos uses the JPEG file as the original. However, you can tell it to use the RAW file as the original instead.
In the Photos app, double-click a photo to open it, then click Edit in the toolbar. Choose Image > Use RAW as Original.
How to Shoot RAW Photos on an iPhone
If you’re like me, you take most of your photos with your iPhone. However, the iOS Camera app doesn’t support capturing RAW photos. However, there are several third-party apps that allow you to do this, such as the free VSCO, which is pictured below, and the $5.99 Halide.
