#1579: Apple “California Streaming” event, OS security updates, Epic Games v. In short, the iMac 5k is the finest photo editing computer ever created, and has won a permanent place at my. #1580: iPhone 13 and iPhone 13 Pro, Apple Watch Series 7, redesigned iPad mini, and upgraded iPad, plus iOS 15, iPadOS 15, watchOS 8, and tvOS 15iMac 5k for Photographers (In-Depth Review).Then I’ll go into detail about how non-destructive editing in Photos works with RAW image files, Photos extensions, and more. That said, non-destructive editing brings with it some confusion, particularly for those working with RAW images or using Photos extensions to do the editing.To shed light on the situation, I’ll first explain how non-destructive editing works in photo applications in general, using Photos as an example. #1577: iPhone 12/12 Pro repair program, fix corrupted Chrome extensions, iCloud Mail custom domains, Chipolo AirTag alternative, 10-digit dialing changesOne of the near-magical features of Photos, and iPhoto before it, is the way it allows you to edit a photo with the assurance that those edits are non-destructive—you can always revert to the original version. #1578: Apple delays CSAM detection, upgrade Quicken 2007 to Quicken Deluxe, App Store settlement and regulatory changes For example, when you choose Save in Microsoft Word, it saves your changes directly to the document’s file, replacing the previous version of the file in the process. Basics of Non-destructive EditingMost applications directly modify your documents. If you are unfamiliar with RAW, you may wish to read a separate article of mine that discusses the benefits of RAW as well as touching on Apple’s new HEIF image format. In this article, I will often use RAW Power as an example, though other Photos extensions work similarly. Now I’m on my own, developing a Photos extension called RAW Power that uses the same RAW engine underlying Photos and Aperture.You cannot rely on the Info pane in the Mac version of Photos to tell you the file type you are editing because it always shows you the file type of the original.) After the edit is completed, this is what is stored on disk:The full-size JPEG is an individual file on disk. (Photos makes JPEGs for all file types, including RAWs and Apple’s new HEIC files. While extremely useful, this non-destructive model can be confusing to users because it clashes with their expectations based on other applications.Photos saves the edit instructions in a location separate from the original file and generates a full-size JPEG (and smaller thumbnail images) that contain the results of the edits. From your standpoint, the image appears to be modified, but the original file remains untouched. The application applies edits to an in-memory copy of the original to produce a real-time preview of the adjusted image.The application may automatically save the edit instructions, or it may wait for you to hit Done or choose Save.

This is the main point of confusion for people. While this is clearly correct, hiding the original reinforces the perception that the original has been modified. The edit instructions are stored in the photo library’s database, along with other information about the image.If you want to continue editing the image at a later date, Photos reloads both the original and the edit instructions and then combines them to display the adjusted image.Outside of editing mode, Photos hides the original photo from view, instead showing the full-size JPEG or smaller thumbnails at every point in the application. Revise or remove individual edits without loss of qualityPhotos always stores its editing instructions in the library’s database. Discard all the edits and thumbnails for an image, revealing the original Instantly show the original image to allow for A/B comparisons Photos never modifies the original RAW images.Why go through all this trouble? Because non-destructive editors offer three important features: It is not possible to make arbitrary edits to RAW sensor data, and from those edits, create RAW sensor data (it is possible to make a linearized DNG, but linearized DNGs are not RAW images). Applications sometimes store the sidecar information inside the original file because most image formats can store miscellaneous data without modifying the pixels or impairing the ability of other applications to read the original pixel data. Sandboxed apps may store the sidecar elsewhere.Sidecars are general-purpose files, so they can also hold thumbnails and miscellaneous metadata such as ratings. For example, for an image named IMG_0005.JPG, an application may store a sidecar titled IMG_0005.xmp or IMG_0005.dat in the same directory. Avast antivirus pro 50677 license keyPhotos ExtensionsAlthough we mostly think of non-destructive editing in the context of the native editing tools in Photos, that’s not the only place it’s used. For these reasons, many photographers prefer the sidecars to be stored separately from originals. In addition, not all applications correctly retain sidecar data from other applications when they write their sidecar data into the original file. Photos stores the JPEG and extension’s editing instructions in the library. When you select a Photos extension, Photos opens the extension and sends it the original file:When you click the Save Changes button in the Photos extension interface, the Photos extension gives Photos back its editing instructions and a full-size JPEG, as shown here:As a result, Photos extensions participate in the same non-destructive system that Photos uses for its own image editor. Instead, they replace the standard Photos tools entirely.As with normal editing in Photos, Photos extensions let you edit only one image at a time—you cannot use a Photos extension to correct white balance in a batch of ten images. To access Photos extensions, start editing a photo and then click the Extensions (···) button at the top of the window.Photos extensions do not add extra sliders to the Photos editing interface. So don’t bother editing a RAW image with a Photos extension in iOS 12. Photos extensions in iOS 12 are never passed a RAW image—they are always given a rendered JPEG. That means you can edit with the RAW Power extension on a Mac and continue editing non-destructively on another Mac with the RAW Power extension, or in iOS with the RAW Power app.This is also how the system works in iOS, with one important limitation. Even better, the Photos extension’s adjustment data is synced through iCloud Photos, allowing you to continue editing with that Photos extension on another device. Again, this is just like Photos does for its own editing system:The Photos extension can show the original, as well as remove or adjust any previous edit made in that Photos extension.

A Fly in the OintmentThis approach works swimmingly as long as only one application or Photos extension edits an image. ![]()
