Key Takeaways
1. Adobe’s Project Indigo is a new camera app for iPhones that uses advanced multi-frame imaging and AI to create RAW and JPG photos.
2. The app merges up to 32 images into a single 16-bit digital negative, applying adaptive color profiles for SDR and HDR outputs.
3. Project Indigo effectively reduces noise in images by combining pixel values from multiple frames, resulting in clearer photos.
4. It utilizes sensor shift technology to achieve higher resolution images by mimicking natural hand movements during multi-frame capture.
5. The app includes features like slow-shutter mode, AI reflection removal, and zero camera shutter lag, with plans for future updates based on user feedback.
Adobe has launched a new camera app for iPhones called Project Indigo. This app uses advanced multi-frame imaging techniques and artificial intelligence to create both RAW and JPG photos. You can find this research project in the Apple App Store, and it works on iPhones running iOS 18.5 or later (like one available on Amazon).
Multi-Frame Imaging Features
The standout aspect of Project Indigo is its multi-frame imaging. This feature merges up to 32 images captured quickly from the same scene into a single 16-bit digital negative for processing and export. With its AI capabilities, the app applies adaptive color profiles to the digital negative, generating standard dynamic range (SDR) and high dynamic range (HDR) output files, either as DNGs or JPGs. While the photos from Project Indigo utilize AI-generated color profiles, they aren’t exactly raw sensor images that are completely untouched; however, users can adjust the DNG images and colors in editing software like Adobe Lightroom.
Noise Reduction Capabilities
The image stacking technique is effective for reducing noise, a feature that has been present in Sony Cybershot cameras since the 2010 DSC-TX7 model. Sensor noise tends to be sporadic, and each pixel doesn’t show the same noise level consistently. By combining the values of pixels from multiple frames, much of the sensor noise can be eliminated, leading to clearer images.
Enhanced Resolution
Sensor shift technology has allowed cameras to produce images with higher resolutions than their actual sensor limits by slightly shifting the pixels with each multi-frame capture, then merging them into one high-res image. This has been seen in some DSLRs since at least the 2015 Olympus OM-D E-M5 Mark II. Project Indigo takes advantage of natural hand and arm movements to mimic sensor shifting while capturing multi-frame super-resolution images.
The app also includes additional functionalities like slow-shutter mode, AI reflection removal, and zero camera shutter lag. Adobe plans to incorporate features that researchers find beneficial in upcoming updates.
