iPhone Long Exposure Photography Trick

Long-exposure photos can transform static scenes into dramatic, light-trailed images. This kind of photography is often seen as a specialty of professional cameras, but a clever trick makes it surprisingly accessible using an iPhone.

Unlocking long exposure with an iPhone

Long exposure photography on an iPhone is often overshadowed by the perceived limitations of mobile cameras. However, the trick in this short clip shows how easy it can be to capture professional-grade effects. The technique involves manually setting a slow shutter speed using the dedicated camera app and applying a few clever settings. While the iPhone camera interface is designed for snapshots, it can handle long exposures with a bit of cleverness. The trick presented on screen uses the Camera app’s ProRAW feature, which allows for extended shutter speeds. ProRAW captures more data, enabling detailed manipulation in editing apps like Adobe Lightroom Mobile. To activate this mode, you have to set “FORMAT” to RAW and tap on “Shutter Speed.” Then you can access shutter speeds as high as 6:08. However, visualizing the results with the phone's native capabilities is difficult. The live preview found in DSLRs or mirrorless cameras allows photographers to gauge their shot before taking pictures. Using ProRAW in the Camera app requires a quick OS switch, making it inherently less intuitive. But complex features don’t always mean best results.

What makes this digital aged classic still iconic

Long exposure images of lights reflecting off traffic lines are iconic. They have become the symbol of urban nightscapes in modern times. Yet, the introduction of smartphones to this field has had a profound impact. Technology, however, has changed the face of photography as we know it. The convenience and accessibility of long exposure photo tricks open up new dimensions to mobile photography. While smartphones have not always been the gear of choice for long exposures, the availability of more lightweight, potent software options has changed the game. Apps like Camera + and ProCam allow you to access the camera modes that weren’t always easily available. Moreover, the iPhone—with its 64 MP camera capabilities—provides insane amounts of raw data for manipulation. In-camera artificial intelligence and image stabilization functions help capture smooth, stable exposures.

Discovering photography magic

A step by step analysis

What makes this trick more interesting is the sheer simplicity of the process. The step-by-step is straightforward. The first step is to switch the Camera app to ProRAW mode. The second step is to go into the ProRAW settings and optimize your settings. The third step is to adjust the shutter speed to the desired setting. You can then aim the camera at your desired scene and click the shutter button once.

Exposure settings

For long exposure photography, shutter speed is the most important setting. It determines how long the sensor will be exposed to light. Shutter speeds are given in increments like 1/100, 1/250, 1 second, 6 seconds, and so on. The slower the shutter speed, the more light and motion will be captured. And the iPhone’s ProRAW mode allows you to control this with ease.

The focal choice

The f-number or aperture controls the amount of light entering the lens. A smaller f-number means a wider opening, allowing more light to pass through the lens. When doing a long exposure, it’s important to choose an appropriate aperture based on the available light and the effect you want to achieve.

Risks in long exposure photography

The iPhone’s capabilities in this regard are still limited. A risk in using this feature is that it will drain your battery. Therefore, unless you plan to use your phone as a tripod, it is advisable to have a portable charger. Moreover, there is the risk of the phone overheating. Long exposure photography can be resource-intensive, and doing it for too long can cause the phone to overheat. Hence, you should be cautious when you are using your phone for this purpose. Finally, one major risk is that the iPhone’s shutter speeds are not as slow as those of a dedicated DSLR or mirrorless camera. Thus, while the visuals might look similar, there will always be a difference in quality. A professional camera will always win over an iPhone.

Practical guide to iPhone long exposure photography in iPhone

Your iPhone's built-in Camera app does not natively support long-exposure photography but tweaking it just a little bit can help you get the desired effect. A simple method is to use third-party apps like AnimaCam or SlowShutter. The apps can help reduce noise and enhance the effect. Also, you can use a tripod to keep the camera steady and get a cleaner shot.

• Use ProRAW mode properly: Make sure you have set your camera to the correct mode to get clear results. ProRAW captures more data, giving you a higher quality and more detail.
• Use a tripod: A tripod will keep your camera steady and help achieve smoother, clearer long exposures.
• Adjust settings: Tweak your camera settings to ensure the desired output. For instance, adjusting the ISO and aperture.
• Be patient: Long exposure photography takes more time to capture a scene in comparison to normal photography. Hence, be patient and handle your phone with care while capturing. This kind of photography is a game of patience. You will learn with more practice. But when mastered, the results of long exposure photography will speak louder than words.
