P: Introducing the Project Indigo camera app

Adobe Employee ,
May 23, 2025 May 23, 2025

This post applies to the Project Indigo iOS camera app. 

 

Adobe Labs is excited to share an early look at Project Indigo, an iPhone camera app we've started to develop, to get feedback from the photography community. The app offers full manual controls, a more natural ("SLR-like") look, and high image quality in both JPEG and raw formats. It also introduces some new photographic experiences not available in other camera apps. For more information on the underlying technology, please refer to thiProject Indigo blog post.

 

Before you start with Project Indigo 

  • We recommend using Project Indigo on iPhone 15 Pro/Pro Max or newer devices.
    (Also supported are 12 Pro/Pro Max, 13 Pro/Pro Max, and all 14-series devices.)
  • You should have at least 1GB of storage space left for the app, the downloadable AI Models inside the app, and for captured photos. 

 

Recipes for success when using Project Indigo 

To get the maximum out of your images captured with the app, follow these guidelines: 

  • When reviewing the results, focus on Project Indigo's more natural look (in both SDR and HDR). If you haven’t done this before, try viewing the images on your laptop or desktop device, preferably on an HDR screen. 
  • Capture with both JPEG and raw DNGs with file saving enabled. Project Indigo produces computational photography DNG files, which have the same natural look as JPEG images, but much more latitude for editing after capture. 
  • Take control of the camera with the built-in Pro Controls, including controls that are exclusive to a computational camera: Frames to Merge and Merge Method. These may be intimidating for beginners, but with Project Indigo, you can try them for free, and nothing will break—you can always reset the settings to ‘Auto’ and let the camera take back control. 
  • Go to the Indigo Labs page and play with the latest innovations our team can offer. These are only available on mobile via Indigo! 
  • Be patient! Project Indigo is doing a lot of heavy lifting under the hood, and it will reward you with great photos. In return, it may ask you for a bit of time to set up captures when needed, and to wait a few seconds for the image processing to finish. 

 

Sending feedback 

Please try the app and share feedback in this community forum thread. If you report a problem you encountered, it would help to include details like which device you are running Project Indigo on, what kind of scene you were trying to capture, what you were trying to achieve with the camera, and as much information as possible about what you like or do not like about the resulting photo quality. Our team will continually monitor this thread to track issues and improve future experiences.  

 

To improve the performance and results of Project Indigo, it is important that examples of images that do not meet your expectations are forwarded to the team via your report.  A large variety of file formats are allowed as attachments in these forum posts. The best option is to attach your image's raw file directly to your feedback post. Note that there is a 50 MB limit on an attachment's file size. If your raw file is too large to attach, the best option is to share the file via a file-sharing service (Dropbox or similar) and then share the link in your feedback post. Thank you for continuing to provide feedback on the Project Indigo camera!

@red0ne Feedbacks are feedbacks, there's no demands here from me nor anyone on this thread as well.  You might have own iPhones and androids like me but you definitely do not know the "scene" of camera mobile photography that exists for example on telegram.  Everyone modding camera apps started with google camera as the pinnacle of computational photography and Marc and his team is definitely putting a repeat of that for iOS, not a exact port if that's what you're talking about.  Also do know that this is after all Marc's bread and butter so he is definitely improving on what he started with, google camera, so if you can't match the level of google camera and then exceed it, why else Indigo would exists.  There's a phlethora of camera app out there already with it's own identity that you mentioned of, but came nowhere close to what google camera is capable of.   

 

Most of the stability feedbacks were overheating, not saving photos if exiting the app too early (my own experience), shutter sounds, improper hdr viewing (udpated in latest iOS beta) seems to be already addressed by the team so the next step would be the obvious fine tune adjustments so people who uses jpeg do not have to tinker with the raws as the raw sizes even after post process to jpeg are quite large, 4-5 times the sizes.

I just registered to express my gratitude and support to the team. I’ve been using Indigo since release and while it's understandably still maturing, it shows a lot of promise. They are clearly aiming for something that isn't just a repeat of what Marc's team started at Google. I own iPhones and a variety of Android phones to experiment with computational photography, and it's clear Indigo is forging its own path.

 

Having said that, I would like to share my view as a developer (albeit of the web kind) on the behavior in this thread. It seems to have turned into both: a wishlist (probably fine) and a list of demands for the team to replicate what other camera apps do, which is particularly appalling when specific solutions are prescribed. The team has repeatedly mentioned they are small, so their budget (time, resources, etc.) is limited. Their time is (probably) best spent improving stability (their stated top priority) and executing on their vision, not reproducing the Google camera or emulating the iPhone's ISP.

 

I bet the best way to get what we want is by helping the team with feedback about specific, reproducible issues. Indigo appears to be an experiment, and its future isn't guaranteed. It needs to be stable and have an identity of its own, which it won’t achieve by copying what came before. This is just my perspective as a lurker who's genuinely excited to see this project succeed.


By @red0ne

Thank you @red0ne - most of what you have written is true. Having said that, we really don't mind a variety of feedback from users. This is after all one of the main reasons we published what is clearly and experimental app: it's to hear both the good, the bad, the ugly, and the demanding. 😉 One of the aspects of our effort is to help educate the general public about mobile photography where we think it matters. Many things that need to happen to get a nice looking image are very difficult to do, and most of us are not really aware of them until we start building a camera app. Here is where working on an iPhone is both a blessing and a curse: on one side it is a very stable (and shareable platform) where we can immediately address many generations of devices, but on the other hand it is quite closed and not very amenable to mods. Things like dual conversion gain are simply not exposed in any way, shape, or form to 3rd party apps, and if we were to find some secret API which allows control over it, our app would not pass the App Store review as, per guidelines, one cannot use such APIs.

Bottom line is, myself and the team are at this point quite versed in not getting upset at any criticism, asks, demands, or any other feedback. We are working as best as we can, and we will be releasing improvements asked by the users when we can.

There's only one person that did it, George, from Telegram group of modders by modifying system binary files.  However, the newest Pixel 10 pro series has DCG exposed since it has white level of 4095 vs 1023.

Here's another night mode auto shot in quite dim lighting.  There is only one street light not in frame to the right.  It took 1s to proccess and I am extremely impressed at what it does in terms of raw!  The shadows can be recovered quite well, if pushed all the way up the dark areas noises both chroma and luma are not blotchy artifacts like previous since it didn't need to drop shutter speed much unlike the other scene.  The sooc jpeg did fine in terms of exposure on how it represents the true darkness of that scene, but too much crushing shadows.

 

The processed jpeg from raw is how I would like night mode to behave vs currently as that look is more zsl instead of psl, which night mode tends to be brighter and have more shadow exposure.  I also removed all denoising in light room mobile and left sharpening untouched.  This amount of noise if done to sooc jpeg is more than acceptable due to the nature of the scene darkness.  Please pass this to the team and see what they think as well in terms of noise to sharpness.

Indigo was a very promising camera app until a few days ago when it stopped writing DNG files.

I tried erasing / downloading Indigo again, tried quitting Indigo then shooting RAW with the native Apple app then back to Indigo. Always wait for the little progress circle over the preview to complete before doing anything else. No quick clicks of the shutter. No overheating.

Nothing has restored DNG functionality (while Indigo is obviously set to DNG+JPG).

Indigo 1.0.2 on iPhone 16 pro / iOS 18.6.2 / available 81 GB / no previous photos saved in Photos / iCloud not used for Photos. 

It should be obvious that not having access to DNG files has made Indigo rather useless.

By @Antonis R

Hi Antonis, this is indeed concerning, but it also sounds very weird - I can honestly say this is the first time I am hearing of this problem. To debug this further, can you answer a couple of additional questions:

  • If you capture JPEG-only, is it always saved correctly?
  • If you capture JPEG+DNG, is the JPEG always saved correctly?
  • How are you verifying that the DNG is or isn't written to disk?
  • Have you tried rebooting the device to see if that helps?

Thank you for helping to triage this.

I have been using Indigo from the start and it became my main camera app (mapped it to camera button)

the main differentiator from stock camera app is color rendition wchi feels much more natural, film-like, less flat and processed. The image has much more plasticity!

Attached few recent pictures (all are straight unprocessed jpegs)

p.s. still waiting for pure astophotography mode

By @karen_5438

Thank you for sharing your images - these all look wonderful! Regarding improvements to long exposure functionality, including the astrophotography mode, these are in progress. It will take a few cycles for us to progressively add more, as astrophotography requires custom processing which differs from regular captures. Stay tuned!

Hi guys,

 

Loving Project Indigo so far. Thanks for building this! I want to share a minor issue I've experienced with the app.

 

I’m using a Japanese-model iPhone and a shutter / notification sound is required when taking photos in Japan (or when the device is in Airplane Mode). However, in Project Indigo the shutter sound plays continuously—even when I’m not pressing the shutter button. This constant sound makes it very hard to take photos in public without disturbing others.

 

Could you please look into this for a fix or workaround? Thank again for building a great app.

By @liyuu_8951

Thank you for reaching out. This is a known issue, due to the fact that Indigo's viewfinder always streams raw frames which are used both for our custom auto-exposure algorithm and for our Zero Shutter Lag (ZSL) functionality. We are working with Apple on trying to enable shutter sound disabling world wide. Please stay tuned.

By @powerful_Elixir5E29

A new build is imminent. Having said that, there are a few things to be aware of here:

  1. Indigo is experimental, and there is no commitment (yet) from Adobe on productizing it. So all effort that goes in it is due to a passionate, but rather small team working on it.
  2. As menioned above, we are a small team. Depending on what an app does one doesn't necessarily need a big team, but Indigo is complex so things take time.
  3. Did I mention that Indigo is complex? Indeed, since we own the full image capture and processing pipeline, making changes is oftentimes a lot more involved than if we were to "just" reuse Apple's capture pipeline. For many 3rd party camera apps adding certain features is really just a bit of UI/UX work. For us it may require that plus a decent amount of messing about with the core capture and processing functionality.
  4. Furthermore, building on the 'experimental' label from above, as we are building Indigo, we often find that the way we did some things initially is suboptimal and may make things slower for the user, or it may make building extensions harder. So we are changing quite a few things under-the-hood which you may not notice any gains from, but which will allow us to do things better or faster later.

 

The team really appreciates the support we are getting from the community, especially here on the forum. We are accutely aware that Indigo has some sore spots that need fixing or improving, and the main one are stability and performance. These will be coming out to our users over time, and the next update already includes some such improvements - for example, I can tease that we managed to improve the super-resolution speed without impacting image quality. Stay tuned for more.
