A RAW photo isn’t even an image-it’s just the ones and zeros describing the light levels for each pixel on the sensor. That said, I leave the option set to High Efficiency and don’t run into compatibility issues in my everyday editing apps in part because iOS usually converts HEIF images to JPEG when you export.Ī RAW file, by comparison, contains only the data recorded by the image sensor. HEIF images aren’t as compatible as JPEG among the galaxy of image editing software, which is why there’s an option to make the iPhone’s Camera app save images as JPEG (Settings > Camera > Formats > Most Compatible). For the sake of simplicity, I’m lumping JPEG and HEIF into the same group: images processed in-camera and compressed. Since iOS 11, the iPhone captures photos in a newer format called HEIF (High Efficiency Image Format), which also applies lossy compression. In most cases, because the algorithm works well, we don’t notice the compression or the smaller bit depth, which is why JPEG has remained the dominant digital photo standard for years. The image data is processed in-camera, so the only photo saved is the compressed version. Its algorithm determines areas of similar colors that won’t be perceived by typical human vision and blends them using fewer colors.
JPEG accomplishes its size reduction by throwing data away, a process known as lossy compression. That was especially important in the past when memory cards were measured in megabytes (MB), compared to today’s multi-gigabyte (GB) cards. JPEG (short for Joint Photographic Experts Group, the organization that developed it) is a file format and compression scheme designed to create good images that are small in size.
To talk about RAW Power requires a quick explanation of RAW formats and how they differ from most of the images your typical point-and-shoot camera captures.

It’s also one of the few tools that properly handles the ProRAW format in the iPhone 12 Pro and iPhone 12 Pro Max, more so than even Apple’s own Photos app.įirst, a disclaimer: RAW Power developer Nik Bhatt has been a guest on, and an early sponsor of, my podcast PhotoActive. RAW Power, an app for macOS, iOS, and iPadOS from Gentlemen Coders, is adept at taking advantage of the options that RAW brings to photo editing. RAW photos can be better-dramatically better, in some cases-than JPEG photos, but it takes some work and know-how to get them there. (To be clear, RAW is not an acronym it’s written in uppercase by convention seemingly only to be parallel to JPEG, TIFF, PNG, and other image formats that are acronyms.)
Plus, since professionals used it (and of course I wanted to be more like the pros), I dove from the high board into deeper photographic waters. RAW was better, I was told, because it encapsulates the raw data captured by the sensor without additional in-camera processing. When I decided to jump from point-and-shoot digital cameras to something more capable, I was faced with a new choice: should I capture images in RAW or JPEG format? Until that point, all my cameras shot JPEG, the imaging standard that can deliver great-looking but heavily compressed photos. #1656: Passcode thieves lock iCloud accounts, the apps Adam uses, iPhoto and Aperture library conversion in VenturaĮditing RAW and ProRAW Photos Using RAW Power 3.#1657: A deep dive into the innovative Arc Web browser.#1658: Rapid Security Responses, NYPD and industry standard AirTag news, Apple's Q2 2023 financials.#1659: Exposure notifications shut down, cookbook subscription service, alarm notification type proposal, Explain XKCD.#1660: OS updates for sports and security, Drobo in bankruptcy, why TidBITS doesn't cover rumors.
