Everything about Apple ProRaw: a full complete review

Apple ProRaw, a new starting point
Apple ProRaw is Apple’s latest technological addition to the smartphone photography industry and sets a new starting point for iPhone photography.
It is no mystery that smartphone photography is increasingly replacing cameras in many situations: myself, who have been promoting it for at least 10 years, I’ve seen a crazy evolution in this sector.
Smartphones are always in the pocket with us and become the perfect tool to photograph our everyday life.
I was able to try Apple ProRaw for a month with the Beta version of iOS 14.3, and this below is my in-depth analyzes after this period of use.
I suggest you also read the full review of the iPhone 12 Pro Max in which you can find many other photographs in addition to the technical data of the lenses and sensors used. I’ve also covered more focused aspects in other articles related the iPhone 12 series:
Why Apple ProRaw is a big deal
Shooting in Raw format has always been a prerogative of digital reflex and mirrorless cameras. It is a “raw” format that allows you to have all the information available to be processed later in the shooting phase.
It is also true that the shot in Raw format was already available from the iOS 10 update which brought this possibility, however, only to Third Party Applications.
Why Apple ProRaw is a big deal? Because it brings this photo processing possibility to the native Apple camera in an easy and intuitive way. There is no need to install additional apps.
Furthermore, the Apple ProRaw format contains more information than a classic raw file. Below I explain these differences.

Apple ProRaw explained
One of the big differences between a “classic” raw and Apple ProRaw is the fact that the latter adds all the information from computational photography calculations to the information captured by the sensor.
We know that Apple in recent years has elevated the results of photographs taken with the iPhone thanks to an improvement in its algorithms. Thanks to the Smart HDR, Deep Fusion and Night Mode functionality, it managed to overcome the technological limitations of smaller sensors.
The Apple ProRaw file is therefore not like a classic raw file of digital reflex and mirrorless cameras that was saved directly by bypassing the processor’s computing system, but is a file enriched with all the computational photography information.
We can therefore say that Apple ProRaw is a “richer” file than a traditional raw file.
Apple ProRaw Dynamic Range
Dynamic range is the ability to record information from shadows to highlights. The greater the dynamic range, the greater the chance to have both shadow detail and highlight detail in a shot.
One of the biggest “disappointments” on the part of my students in photography classes is noticing a big difference between what they see with their eyes, in a high contrast situation, and what the camera captures.
In the current state of sensor technology there is a limit of recording information obtainable with a single click. We cannot therefore expect, in high contrast situations, to have the same “vision” as our eye (which in any case remains unique, photography is always a personal interpretation).
This is where the new computational photography algorithms such as Smart HDR come into play. So imagine that when you expose the photograph with your iPhone, the smartphone actually makes a lot of exposures which it then merges together.
Now, thanks to Apple ProRaw, all this information is available to the user even in post production.
I wanted to do a test in a very difficult lighting situation: take a picture in an alley on a street in Florence where, due to its narrow shape, little light enters at the time I was take this picture. In the background appears an iconic palace of the city: the bell tower of Arnolfo di Palazzo Vecchio.
So I did an exposure for the lights (that’s what I recommend you do almost always with Apple ProRaw). The result of the photo obtained is what you see below on the left. Then I worked directly in the iPhone Photo editor (which at the moment is one of the best solutions for editing Apple ProRaw photos for free) and you can see how much information I was able to recover in the shadows! (second photo) This information is present in the file and it’s there for you to be recovered!
The third photo was edited with Capture One Pro.
I suggest you to give a look at the smartphone review page where you can find other articles about smartphone photography :
Apple ProRaw details
At the moment the way chosen by Apple for the ProRaw is to process out the Noise Reduction directly in the calculation phase with computational photography.
What we get is therefore an already clean file without any digital noise. On the one hand, therefore, it facilitates the subsequent work for a novice user, on the other hand, however, there is a lack of general sharpness when we zoom in on the photograph a lot: we will notice that all the details are “washed out”, which is typical files that have been “excessively” cleaned of digital noise.
Let’s say that the path taken by Apple in this case was to privilege a clean file over a file with more details. I think the choice was due about the usual destination of smartphone photographs: social networks.
If we think that posting on Instagram the picture get resized to 1350px on the long side, we understand how in most cases it is almost impossible to zoom in to notice the finest details on these social network’s posts.
If you are a lover of detail at the expense of a greater noise in the file, in this case you will have to look at other solutions, such as Raw taken by Halide Camera App.
I point out in any case, that also the correction of the vignetting and the natural distortion of the lens (not the perspective distortion!) are already applied in the Apple ProRaw file.
Apple ProRaw: Are there any slowdowns when using this format?
It was one of the questions I asked myself, especially thinking of digital cameras where many times, the burst changes if I only activate the Jpg or Jpg + Raw shot at the same time.
I must say that activating the Apple ProRaw file, during the portrait session I did with the iPhone 12 Pro Max, I did not notice any kind of slowdown compared to shooting in the basic Heic format.
This is a proof of the great computing power of the new Apple A14 Bionic chip combined with a greater Ram inside the iPhone 12 Pro series: we have no slowdown when we shoot with Apple ProRaw.
Apple ProRaw: how to edit the file for free on iPhone?
What is the easiest, fastest and free way to edit Apple ProRaw photos? Use the Apple Photo application. Apple has therefore made an update to its application to allow us to easily and quickly edit the Apple ProRaw files.
At the moment it seems that the native Apple Photo application is the one that also manages to recover more shadow detail than Lightroom CC and Capture One Pro.
It must be said, however, that in many situations where there are gradations, such as in the example of the skies, artifacts (banding) can be seen, which is not the case in the developments obtained with Lightroom CC and Capture One Pro.
Apple ProRaw, some problems that may arise
I noticed in some photos, especially those that have shades of color as in the case of the skies, some banding artefacts when I shot with Apple ProRaw.
To remove these defects, you need to enter the “Edit” mode of Apple Photo and act slightly recovering some of the exposure and the highlights. This usual help to make this defect disappear.
Apple ProRaw in Lightroom CC and Capture One Pro
What other software besides Apple Photo can I work with Apple ProRaw files? Being a universal Raw DNG format, all software that supports this format can open these Raw files.
I have personally tested the Apple ProRaw files with the two software I usually use: Lightroom CC and Capture One Pro.
Both software therefore open files regularly, even if in both cases, we find (as in the case of all raw files from smartphone) a file that looks very different from what we see as a “preview” on the screen when we look at it on our smartphone.
The reason is obvious: the ProRaw file has a “preview” in the Apple Photo gallery that matches the one of the iPhone default shot.
But when we open this file in Lightroom CC or Capture One Pro, the programs recalculate a new preview that shows the pure captured data. Consequently, in the case of Apple ProRaw files, we will almost always see an underexposed file that needs to be corrected in order to have a correct interpretation.
Generally, I noticed more detail (by adjusting the Noise Reduction and Sharpening parameters) within Capture One. Even with Lightroom I get excellent developments with excellent recovery of lights and color in general.
Apple ProRaw and Night mode portraits?
Apple ProRaw can be activated in basic photo modes and also when Night Mode is activated.
It is not available in portrait mode and therefore not even in the night portrait mode introduced by iPhone 12 Pro.
Apple ProRaw vs Halide Raw
This was an interesting test. Halide Camera App was the application I used the most with iPhone Xs during this last year before the arrival of the iPhone 12 Pro Max. I used this App for all the photographs I wanted to take with a manual control.
At the moment (Halide App version 2.0.5), the App uses a traditional Raw DNG format capture. What does this mean? Which still fails to exploit all the computational photography algorithms I described above.
Halide’s raw is therefore an “old school” raw like for cameras. A Raw that comes out directly from the sensor.
Where then can we see the differences? We see them when we analyze the images side by side with 300% zoom. We will see a big difference in the details as reported in the upper paragraph.
We understand that at the moment, Apple’s direction with the ProRaw has been to favor a very clean file (little digital noise) at the expense of details when we zoom very very closely.
In the case of the raws that come out of Halide Camera App we have an opposite situation: a file that did not have the benefits of computational photography as far as noise cleaning is concerned, so it has much more noise, but at the same time has more detail.
The problem with raw files in Halide arises when we shoot automatically in low light and the application, for reasons related to the photographic technique, will raise the ISO.
Files taken with the Halide App therefore suffer much more from the increase in ISO than files taken with Apple ProRaw.
Apple ProRaw, how to enable and use it
To activate the Apple ProRaw is very simple. I walk you through the steps to enable it on iPhone 12 Pro and iPhone 12 Pro Max:
Go to Settings -> Camera -> Formats -> Activate the item “Apple ProRaw”.
Later in your Camera App you will find at the top right a button to activate and deactivate recording in Apple ProRaw format. I remind you that if you activate this setting, it will remain so as long as you use the camera. At the next restart the Raw capture will be disabled. If you want to make ProRaw format always active, you need to be sure that this option is checked:
Go to Settings -> Camera -> Preserve Setting -> Apple ProRaw.
I remember that Apple ProRaw works with the basic camera mode, in the Night mode and also for the front camera. It does not work in portrait mode.
Apple ProRaw file format
The format in which Apple ProRaw files are saved is the Adobe DNG universal format. This is the best choice that Apple could make in order to immediately have total compatibility with all software that read this universal format from Adobe.
Apple ProRaw File size
The weight of Apple ProRaw files varies from 11 Mbyte to 33 Mbyte. It is highly variable depending on the scene, the lights and colors captured within the file.
When Apple ProRaw will be Available?
Apple Pro Raw is available from iOS 14.3 that was released on 14/12/2020.
Apple ProRaw supported devices

Will Apple ProRaw come to iPhone 11 Pro or other previous iPhone?
It is difficult to imagine this. If Apple ProRaw had been planned for other iPhones then this news would have already been given by Apple for some time. I am sure that the limitation is partly due to further boost sales of the new iPhone 12 Pro series, on the other hand by some hardware advantages (more ram?) present only in the iPhone 12 Pro series at the moment.
It may be probable, however, that Apple will decide next year, perhaps with the time available to further optimize the algorithms, to extend Apple Pro Raw to the basic versions of future iPhones (subsequent iPhone 13 series).
Is Apple ProRaw worth it?
If you ask me if it deserves to keep recording in the Apple ProRaw format activated, I obviously say yes as the extra data allows you a great versatility in file editing.
In fact, many times, the photograph taken quickly suddenly (as in my case the title image here) turns out to be one of your favourite shots. Therefore, having the file with all the information at your disposal to be able to modify it is a great advantage!
I hope in the future that Apple will give the possibility to save the development presets in the iOS App and on Mac Os and that it will allow a Copy / Paste setting of the development settings (option that is already available in the version of the App on Mac Os ).
I hope perhaps an option to reduce the amount of Noise Reduction applied and have more detail available even at the expense of more noise. Let’s see what the future updates will bring!

Hello Alessandro, thanks a lot for your very good review.. all’ what I wanted to know about Apple ProRaw is well explained. I’m using as standard APN a Canon 5D with C1 for CR2 images. But will get soon an iphone 13 pro which allows to work with ProRaw files. It’s possible to get a Raw photo with older iphones, mine is from end 2018, if using «ProCamera » app, but all features of ProRaw are not included, I guess you must have I12 Pro or above.
Will come back when tries are done in different situations.
But unfortunately the demo file on your site seems to be not reachable ? Ok, the most important details are given actually.
Alessandro MichelazziPosted at 22:37h, 19 January
Ciao Michael, I think it’s missing the links for the AppleProRaw since I’ve changed some things with the hosting and in the process some links and file got missing… Thanks for your works and happy you find it useful!
Stephen DixonPosted at 13:41h, 07 April
Thank you for putting together such a detailed and thorough set of articles demonstrating the various capabilities of the iPhone 12 Pro Max. I see that you are a Capture One user as well and so wondered if you have had a chance to use the latest version of Capture One and experiment with its support for Apple ProRAW image files to see if this makes any better improvement in what you can do with your images. I haven’t had chance to do this myself so was interested to hear your thoughts.
Alessandro MichelazziPosted at 17:44h, 13 April
Hello Stephen! Well, I’ve to say that Capture One Pro supports DNG since some versions, so Apple ProRAW files are read by the program. The problem however arises since there’s no proper color profile and tone map support for the Apple ProRAW inside Caputre One Pro (at the moment, maybe in the future this can change). The result is that the file you import will be quite dark with a lot of work to do to address the problem.
This is why I’m working on my own custom profile for Apple ProRAW (you can pre-register on this page: https://products.alessandromichelazzi.com/smartphone-raw-presets-lightroom ) to be able to have a good base for any photo shot in Apple ProRAW when opened in Capture One. At the moment I’m focusing to release for Lightroom, then the next will come to Capture One Pro. So let’s keep in touch!
Rima HerberPosted at 03:45h, 02 April
I usually use photoshop(C6) via bridge for the raw images, but when I download the raw images from my iPhone 12 pro max, they are in the dng format and I find they don’t perform well in Bridge. Can you recommend a process for me? I want to be able to process the dng files using photoshop, if possible.
Alessandro MichelazziPosted at 17:47h, 13 April
Hello Rima. The process you are doing is correct. Apple ProRAW is saved as a DNG universal format so you can open it using Camera Raw from Bridge or Lightroom. Recently Adobe has updated its programs with a new profile that matches the tone mapping of the photo as you see on the iPhone gallery. My own Apple ProRAW color profile and presets (https://products.alessandromichelazzi.com/smartphone-raw-presets-lightroom) will have the opportunity to have a good color and tone rendering even if you don’t have the latest version of Photoshop / Lightroom updated.

Thanks for the answer. Again great review and i love the iPhone 12’pro max camera
Now i have to learn how to copy and paste edits on my Mac!
Mark WeinribPosted at 05:41h, 04 February
Thank you for the reviews. I have the 12 pro max and this was really helpful. However, I didnt understand what this meant:
-the development settings (option that is already available in the version of the App on Mac Os –
What are the development settings?
thanks again and I look forward to your reply
Alessandro MichelazziPosted at 16:07h, 09 February
Hello Mark. What I mean with that sentence is that, if you are using Apple Photos App on Mac Os you can Copy / Paste the editing between raw files (but not save presets). On iOS you can’t save presets of a certain edit nor copy / paste it to another shot you have in the gallery… For this feature you have to use an App like Darkroom.
IgorPosted at 11:18h, 16 December
Many thanks Alessandro for you review.
To those who want to buy the best smartphone for photography would you recommend the iphone 12 pro max or do you think there are better alternatives?
Alessandro MichelazziPosted at 12:20h, 16 December
Hello Igor, thanks for your comment!
Well, I think that iPhone 12 Pro Max has a slight edge over the competitor at this time. I think not only talking about the pure image quality, but the full workflow: from shot, to editing (inside Apple Photo without any need of extra applications) to the complete iCloud storage. Not considering all the unique App on iOS like Halide Camera App, as mentioned in the article. All these aspects gave a clear added value to Smartphone shooters. If you like more the Android side, I would suggest then the Google Pixel 5, on witch I will cover soon a full review!
Romain MaletPosted at 12:37h, 15 December
Perfect i m waiting … 😬 but from iPhone XS, thé upgrade talking about photo part Does Not disaponted you?
Romain MaletPosted at 21:16h, 14 December
Thx a lot for you article I was writing it as a Messi ! I m going to play with your raw file in Lightroom I give my opinion here, first question before playing with the iPhone 12 pro max, are you impressed by the result ? Or it s ok nothing more ?
I played around a little I m a kind of disappointed a little bit maybe my expectation was too high. Have you tried to take picture with tripod ? In good light I m not sure the are are better than the iPhone X don’t you think ?
Alessandro MichelazziPosted at 09:30h, 15 December
Hello Romain. Well, I think that at the moment Apple ProRAW deliver some good results especially for the dynamic range of the lights. In this fields it’s far away better than any other file from previous iPhone.
If we talk about details, yes, it’s a bit disappointing. But as I’ve mentioned in my article, Apple’s decision was to sacrifice detail in exchange for cleaning the file.
Halide Camera’s latest update (2.1) introduces a ProRAW + variant which I think is intended to bypass the noise cleanup. I am already doing some tests with it and when I have some new material, I will update the article! 😊
