![]() The trouble is that the HDR data in HEIC is not documented and there doesn't appear to be a way we can decode and encode this data. ![]() We do support high dynamic range in Pixelmator Pro – say if you open a RAW image on a display that supports this feature. In the process, figure out this whole iPhone photo situation.īy Andrius 13:39:51 Hi guys, we have actually spoken to some folks at Apple about this and as far as the issue goes, you've hit the nail on the head with the following: Democratize this technology and allow users to experiment with these new displays. It's time an application pioneered HDR photo creation, with true HDR results to view on an HDR display. The new displays are really one of the best parts of the new devices, period. It is time we get real support on here from Pixelmator. Being stuck with SDR content on these displays is common because truly HDR compatible displays were too expensive to matter for far too long. All three of Apple's major product lines support have XDR displays. But here's a more generalized suggestion. If anyone can get to the bottom of this it is you. Where is this extra data stored? Has Apple told anyone?īack to Pixelmator. This is quite a unique phenomenon that I don't feel has gone noticed. You'll see the brightness immediately reduce as the image becomes SDR. Want to test it? For those at Pixelmator who have a MacBook Pro with an XDR display, import this provided image into Photos app, then edit it in the Pixelmator Pro module. Editing iPhone photographs outside the first party controls will immediately remove this HDR and kick the picture back to SDR. This has clear implications for Pixelmator Pro, or any other photo editor. The only problem is that Apple has not documented any of these features for images. HLG is a new technology supported in Dolby Vision video on iPhone which makes a file compatible with both HDR and SDR displays. Which, if my suspicions are correct, overcomes the limitations of. So, they're most likely using this form of HDR coded to HEVC inside an HEIF file with HLG (Hybrid Log Gamma) support. Apple notably added Dolby Vision video recording in iPhone 12, which is saved in the. HEIC file format is actually just a container format for. Here's at least my guess on how it works. Images in this format are brighter, more lifelike, and take advantage of XDR displays. I'm an amateur when it comes to understanding file formats, color space, or high dynamic range. ![]() ![]() What does this mean? There is high dynamic range data in processed iPhone photographs that no app other than Photos or Camera (and Preview) knows how to view. ![]() To make things weirder this data is found in the. This is actually extremely uncommon and Apple is surely the ONLY company doing this at the moment with processed images. This is not just an “HDR processed” image that’s compressed to SDR. Big difference on something like an OLED or MiniLED display. If some of you are confused I’m talking about the image equivalent to the difference between an SDR video and an HDR video. True HDR that takes advantages of XDR displays in the new MacBooks, iPads, and iPhones. But it seems as if Apple has included true HDR, perhaps even Dolby Vision, in their processed photographs with little notice. This gives the “HDR look” a la Google Pixel. For photography it’s well known as a feature to use multiple exposures, bracket them, and compress dynamic range to fit onto SDR displays. I’ve been exploring HDR image editing recently to test the Pro Display XDR on my new MacBook Pro and finding information about actually getting a true HDR image seems uncommon. Or you may notice more highlight detail in the Photos app compared to a third party app. Some of you with newer iPhones (I assume starting with iPhone 12, but can't confirm.) may notice the images become brighter than the rest of the display when viewing. What if I told you Pixelmator, and every other photo editor on the planet, is missing critical information from iPhone photos? ![]()
