P: Introducing the Project Indigo camera app

Thank you for your message. To offer all of its features, Project Indigo requires a minimum of 6GB of RAM on the device. To ship Indigo on devices with less memory would probably require sacrificing some features, which is possible but is not our priority for the time being. As we develop additional features and further optimize the application speed we will keep reevaluating the opportunities to support older devices.

Thank you for your message and for sharing your experience. The issue you found is due to the Optical Image Stabilization (OIS), which physically moves the lens to keep the frame stable in presence of handshake. While the viewfinder is running we stream raw frames for ZSL capture, and those frames do not use OIS. That's why the viewfinder and final capture FOVs match. But for Night mode the capture does use OIS with the shifted lens position, while the viewfinder still does not, hence the FOV difference. We will explore options to mitigate this problem in the future.

is there a way to disable the HDR mode for captured jpegs ?

Hi Peter - there is no way to disable HDR for JPEGs. But the SDR-look is in each JPEG because they are written as base (SDR) + gain map (HDR), per the ISO standard. The ecosystem is sitll being worked on, but more and more tools are properly supporting displaying SDR and HDR correctly, depending on whether the display used for viewing can support HDR or not. 

Out of curiosity, can you tell me what is the use-case for SDR-only JPEGs?

I used Lightroom on the desktop for 10 years so I have done post processing. But I got frustrated with the whoie SD card dance. The cloud sync dance is no better. I'd love it if this app would do limited post processing in the future. Basically my ideal workflow is (I don't do video): 1. shoot with a LUT 2. 10% of the time do some light post processing but just basic contrast, vibrance etc, no cropping nothing major 3. post to flickr 

Hello - thank you for your message. Current behavior is as follows:

• If Indigo is paused while "regular" images are being processed (images without the multi-frame super-resolution) then processing will continue once the app is started again.
• If however the app is paused while SR images are being processed, it is likely that the captures might be lost. That is why we show a tip the first time a user captures an SR image to warn of this behavior and recommend not pausing the app.
• Finally, if the app is not just paused, but killed (the OS may kill the app if another app is launched that needs a lot of resources), then shots are likely to be lost in either case.

iOS and Android differ greately in how they handle background tasks. Similarly, Halide and Indigo differ greately in how they process images: Halide uses built-in iOS image processing while Indigo's processing is fully custom. Those differences make it challenging to do processing while the app is paused. We are always looking into preventing crashes and lost shots, so this issue is at the top of our priority list.

Thank you for your message. Supporting iPads is on our TODO list, but it will take extra time to tune the UI and the camera performance, so for the time being we are prioritizing iPhones. 

Hello - thank you for your comment. We are very happy to hear you are enjoying Project Indigo.

To get the "water into silk" effect, follow these steps:

• Switch to Night mode
• Turn Pro controls on (button on bottom right)
• Open the rightmost Pro control
• Switch the Merge Method to "Long Exposure"

Note that for Long Exposure to produce good results, you should be on a tripod as any camera motion can introduce blur across the field of view. In addition, you may want to adjust the Frames to Merge parameter above the Merge Method and try valuas all the way up to 32. The more frames get merged, the more "silky" the effect will be.

Hello - thank you for reporting the issue. This is not previously known to the team: can you share a DNG with us so we can inspect it in more details? Also, can you share some more details about when the issue appears:

• is it for every capture, or just some?
• does it depend on the mode, e.g., more common in Night mode?
• how does it react when you manually change white balance?
• how does it react when you manually change the exposure settings (shutter speed or iso)?

To get the DNG to your computer, you can use a cable connection for transfer, or if you have a Mac, in Apple photos you can use AirDrop but make sure to go to 'Options' in top left and click on the "All Photos Data" toggle.
