I downloaded a sample iPhone 16 Pro ProRaw DNG JPEG XL file from the internet. It opened in Nitro just fine and seemed to take edits like older ProRaw files that I’ve edited in the past. Is there anything different about editing this new DNG file type that we should know about? Thanks!
It’s not a RAW file, and it’s not a ProRAW file. It’s relatively new file format that is intended to replace JPEG. It seems that Apple is using the DNG format to hold the JPEGXL data (since DNG is a general purpose container and not a RAW-specific container). At this point I don’t have any tips – it should just work.
Thanks, Nik – but when the sample file is opened in Nitro for iPad, both the tone map and RAW tuning sliders appear to be active. Not sure what to make of that. I checked the file in ExifTool and it appears to be ok. John.
This is a link to where you can download the sample file I’ve been testing. Thanks, John.
This is a link to the source of the sample file – thanks, John.
These are weird files. They act like ProRAW images – my code shows the sliders for ProRAW (and regular RAW) and they seem to work too, so….hmm.
These files do NOT work on earlier OS versions (Ventura, for example is not supported).
This will no doubt cause a lot of havoc as people take shots with their new phones and cannot open them on their older Macs and devices.I have also read that these files contain a regular jpeg that will open when the ProRaw DNG wrapper is exported to a device or app not otherwise supporting ProRaw DNGs. In ExifTool these files look like linear DNGs, but I’ve not been able to find a lot of real information out there. In part, perhaps, because the early reviewers of the iPhone 16 Pro / Max were caught by surprise by this new output option and didn’t have time to make the usual comparisons. Thanks for looking into this, John.
