Hey guys,

I’ve been experimenting with handheld multi-frame photography on iPhone.

The goal is to get long-exposure style effects without a tripod — things like light trails, cleaner static backgrounds, and motion-composited shots from multiple frames.

The hardest part is hand-shake. Even tiny camera movement can ruin the final image, so stabilization before combining the frames became a big part of the work.

I also tried an early Action Shot-style result inspired by old Lumia/Nokia cameras. It is still rough, especially with shadows and difficult lighting, but the first prototype is starting to work.

Just wanted to share one of the early results here.

I’ve been working on an iOS camera app called LSC, mainly around computational photography and image processing on mobile hardware.
The app currently has several modes:

Light Trails
A long-exposure style mode that accumulates bright/moving regions over time. It is mainly useful for light trails, traffic, night scenes, moving lights, etc.

Motion Clean
A frame-averaging mode that tries to remove moving objects from the scene. For example, if cars or people pass through the frame during capture, the final image can keep the static background and reduce or remove the moving objects.

Action Shot
This is the new mode I recently added. The idea is to capture movement over time and composite selected moments of the moving subject into a single image.

For Action Shot, I’m currently using a mostly old-school computer vision / deterministic image processing approach rather than generative AI. The pipeline is based on frame differences, motion masks, morphological filtering, and compositing.

It works in many simple scenes, but it is still a first version. Motion detection can produce bad results in shadows, reflections, low contrast areas, and some difficult lighting conditions. So yes, it can make mistakes, but the core idea is now working and I’ll keep improving it.

One of the harder parts was dealing with hand-shake. Since this is meant to work handheld, even small camera movements can break the masks and compositing. I added a stabilization step to reduce hand-shake before processing, which helped a lot, but it is still an ongoing part of the work.

I originally started this because I missed some of the old Lumia/Nokia computational photography features, but from a DSP / image processing point of view, it became a pretty interesting problem: frame alignment, temporal accumulation, motion detection, mask cleaning, and image compositing on mobile hardware.

Any feedback from people working with signal processing, image processing, or computational photography would be very helpful. Good or bad results both help me improve the algorithm.

I’ve added the first version of a Lumia/Nokia-style Action Shot feature into LSC Long Shot Camera.
It’s still early, and yes, it may make mistakes in some scenes. But the main idea is already working: capturing movement and combining selected moments into a single image.
My goal is to bring back some of those old, beautiful, nostalgic Nokia/Lumia camera features on today’s phones — step by step.
With your feedback, shared results, and suggestions, I believe we can improve it and make it much better over time.
I also added a stabilization filter to reduce hand-shake issues during handheld shots.
If you try it, please share your results — good or bad. It would really help me. 😊

Back in the Lumia and Windows Phone era, one of my favorite camera features was Motion Shot.
It could combine multiple positions of a moving subject into a single image, creating those iconic action sequences that looked almost impossible to capture with a phone.
I’ve been working on a long-exposure and computational photography app for modern smartphones, and recently decided to add a modern version of Motion Shot as one of the upcoming features.
It made me realize how many creative camera ideas disappeared over the years, even though smartphone hardware became dramatically more powerful.

Some features I still miss:
• Motion Shot
• Cinemagraphs
• Refocus

What old Nokia/Lumia camera feature would you most like to see make a comeback?
I’m genuinely curious because there are probably other forgotten gems worth bringing back.

Hi all,

I’ve been working on a mobile computational imaging application called ClearView Cam (Lite/Basic/Pro), focused on improving visibility in challenging real-world conditions such as fog, rain, snow, haze, smoke, dust, glare, and low-contrast environments.

The goal of the system is not to generate visually pleasing or AI-generated imagery, but rather to recover and emphasize scene information that may already exist within the incoming signal but is difficult for the human eye to perceive under degraded atmospheric conditions.

The entire processing pipeline runs locally on ARM64 mobile CPUs without relying on cloud processing, neural network inference, or GPU-based rendering frameworks. The emphasis has been on deterministic, low-latency image processing that can operate in real time on commodity mobile hardware.

Some of the areas explored during development include:
* Multi-stage local contrast enhancement
* Dynamic luminance normalization
* Adaptive color balancing
* Visibility recovery under atmospheric scattering
* Preservation of fine spatial structures
* Noise suppression while maintaining edge information
* Real-time optimization for mobile CPU architectures

The project originated from an interest in computational imaging for situations where visibility directly impacts situational awareness, such as driving, outdoor observation, industrial monitoring, and long-range visual inspection.

Here is an example showing the processing pipeline and the resulting visibility enhancement under adverse environmental conditions.

It’s been an interesting exercise in balancing computational efficiency, image fidelity, and real-time performance under strict mobile hardware constraints.

I’d be interested to hear from others working on computational imaging, embedded vision systems, or CPU-optimized image processing pipelines.

Over the last few months I’ve been working on two apps focused on long-exposure and computational photography:

LSC Long Shot Camera
Capture long-exposure style photos directly from your iPhone camera.
https://apps.apple.com/us/app/lsc-long-shot-camera/id6773305290

LSC Studio
Convert existing videos into long-exposure photos directly on-device.
https://apps.apple.com/us/app/lsc-studio/id6775602955

LSC Suite
Includes both apps in a single bundle.
https://apps.apple.com/us/app-bundle/lsc-suite/id1896880751

Features include:
• Light Trails
• Motion Clean
• Moving Object Reduction
• Fully on-device processing
• No subscriptions

The project started as an image-processing experiment and evolved into a complete mobile computational photography toolkit.

I’d genuinely love feedback from photographers, creators, and anyone interested in computational imaging. 📸
