What is Reeheld?
ReeHeld is a revolutionary iOS camera app designed for capturing stunning long exposure photos on iPhone without the need for a tripod. It is a point-and-shoot camera app that lets you shoot long exposure photos handheld, producing high-quality images in JPG format that are extremely well-balanced thanks to Apple's Smart HDR and can be easily shared right out of the app without necessarily requiring editing.
The app utilizes cutting-edge artificial intelligence and the Neural Engine of your iPhone to stabilize images, resulting in sharp, clear, and stunning long exposure photos. ReeHeld uses computational photography and a smart Frame Averaging algorithm to take a series of photos over a time period between 1 and 30 seconds, then averages them together to create the long exposure capture. The AI smartly recognizes the sequence of images captured and aligns them to produce a final image that is sharper, clearer, and has less noise than individual photos.
ReeHeld features key capabilities including no-tripod shooting for motion blur shots, AI-powered stabilization for best image quality, 1-30 second capture duration, and metal graphics that boost iPhone's GPU to run millions of calculations per second. The app has a simple and intuitive interface that allows quick adjustment of capture time and focus.
This tool is perfect for both professional photographers and amateur enthusiasts who want to take stunning long exposure shots on the go. It is particularly well-suited for amateur photographers looking to experiment with long exposure photography, or for those who want to capture breathtaking images of landscapes, cityscapes, waterfalls when not carrying a tripod.
ReeHeld differs from other Reeflex apps: unlike ReeXpose which focuses on Bayer RAW long exposure requiring post-processing, or Reeflex Pro Camera which offers full manual controls for both still and slow shutter photography, ReeHeld is designed specifically for handheld long exposure with automatic balancing and no editing required.

Frequently asked questions about Reeheld
How does ReeHeld allow you to take long exposure photos without a tripod?
ReeHeld utilizes computational photography and a smart Frame Averaging algorithm to take a series of photos over a time period between 1 and 30 seconds, then averages them together to create the long exposure capture. The app uses the Neural Engine (AI) of the iPhone to smartly recognize the sequence of images captured and align them together, averaging out differences between each photo to produce a final image that is sharper, clearer, and has less noise.
What do I need to have in the scene for ReeHeld to work properly?
You must include a fixed object in the scene as a reference point, like a tree, rock, building, or shore. This is essential for the AI algorithm to have a reference point to work as designed and process smart image alignment. The AI recognizes it and grips on it to align images and neutralize camera shakes. Without a fixed reference (like pointing at only horizon with sea/sky or only clouds with no fixed object), the app will not produce the desired long exposure effect.
Do I still need to hold my iPhone steady when using ReeHeld?
Yes, while ReeHeld's cutting-edge AI technology does an amazing job stabilizing long exposure shots, it's still necessary to hold your iPhone as steady as possible. The 6-Axis Stability Indicator will guide you in keeping your hand stable to mitigate unwanted movement. Keep steady and your photos will be sharp and memorable.
What capture duration can I use with ReeHeld?
ReeHeld allows you to shoot long exposure photos with a capture duration ranging from 1 second to 30 seconds. You can select the desired capture duration (frame averaging exposure time) based on your subject and desired effect. Experiment with different exposure times starting with shorter duration and gradually increasing until you achieve the desired effect.
What image format does ReeHeld produce?
ReeHeld produces photos in JPG format. Thanks to Apple's Smart HDR, the photos captured are extremely well-balanced and can be easily shared with fellow photographers right out of the app, not necessarily requiring editing. This differs from ReeXpose which produces Bayer RAW DNG files requiring post-processing.
How do I use ReeHeld to take a long exposure photo?
Follow these steps: 1) Select the desired lens and field of view for composition, 2) Select the capture duration (frame averaging exposure time), 3) Set focus by tapping the screen, 4) Make sure to include a fixed object in the scene as a reference point, 5) Tap the shutter button and keep steady, 6) Watch the magic unfold in real time.
What subjects work best for long exposure with ReeHeld?
Long exposure photography is particularly effective when there's movement in the frame. Look for interesting subjects like waterfalls, waves, traffic, or people walking to create dynamic and engaging photos. Lateral movement across the scene will be more prominent than movement directly toward or away from the camera. Fast moving clouds are also a fantastic addition to long exposure captures.
Why does my ReeHeld photo show blurred diagonal black shadows on the edges?
This is a sign that the AI cannot understand what to align because it cannot find a fixed reference point. If you're pointing ReeHeld at the horizon with only sea and sky, or at the sky with only moving clouds and no fixed reference, the app will not produce the desired long exposure effect. You need something fixed in the image (a rock, far-away object, building) for the AI to latch onto.
Can I zoom when using ReeHeld?
Zoom by pinching is disabled in ReeHeld to avoid the AI not latching onto stationary objects and to mitigate any possibility of error. The Neural Network requires a certain level of stability to recognize images captured and produce desired frames alignment/averaging. However, you can use the different iPhone cameras available (Wide, Ultrawide, Telephoto) for different levels of magnification.
What iPhone models and iOS version does ReeHeld require?
ReeHeld requires iOS 17.3 or later and works on iPhone. It is also compatible with Apple Vision requiring visionOS 1.1 or later. The app is 22.3 MB in size and is categorized as Photo & Video. It supports multiple languages including English, French, German, Italian, Japanese, Korean, Portuguese, Simplified Chinese, and Spanish.
