ReeXpose is the best app for long exposure photography on the App Store. Designed by professionals for professionals, ReeXpose closes the gap between your iPhone and a DSLR camera, allowing you to shoot long exposure photos in RAW. All without the need for additional ND filters!

Select your capture mode, adjust your exposure, chose your capture duration and ReeXpose will do the rest. The result will be a single, 12-bit DNG file editable in your favorite editing software.

Use the “motion blur” mode to make people disappear, smooth the movement of clouds, or give running water a characteristic silky appearance. Use the “light trails mode” for stunning star trails or to transform moving cars into gorgeous rivers of light. Enjoy the flexibility of full manual controls and the extended dynamic range given by RAW files.

ReeXpose is brought to you by REEFLEX, the small studio behind the development of Reeflex Pro Camera and ReeHeld.

• Note #1: *The RAW format is not supported for the ultra-wide camera on devices older than the iPhone 12 series (this is a limitation given by the manufacturer - Apple)
• Note #2: **As usual for long exposure, you must use a tripod and keep the phone as steady as possible. The app does NOT stabilize the images automatically. If this is what you're looking for, then please have a look at our other app (ReeHeld)
• Note #3: ***Bayer RAW images, which are the standard in professional photography, necessarily require editing in post-production in order for you to obtain a properly elaborated photo. The RAW image captured differs from what you see in the live-preview when shooting, as the live preview is based on the elaborated live output which is in JPG. Hence you might notice differences in what you see on the screen when shooting vs the final DNG image (Bayer RAW). We, therefore, suggest fine-tuning your exposure by manually adjusting SS and ISO, and taking several shots in order to find the best settings for your desired shot.

Great App - Needs 1 Update

I really like this app. I got it to use with my telescope to do a little bit of astrophotography. The only thing I feel that it needs is the ability to trigger the shutter using my Bluetooth remote shutter release. I realize I can use the shutter release timer but I would prefer to just be able to press the button on my shutter release to take each exposure. Other than that it’s a great long exposure photo app that I am glad I got.

Hi Thom,

Thanks for taking the time and sharing your experience with us - it’s highly appreciated!

The Bluetooth remote shutter is present already but not working perfectly yet , as it is still under development. This is the reason why we don’t mention it as one of the app’s features. You can find the details on how to use the Bluetooth remote shutter in here:

For any question or feedback, feel free for reach out to us directly at:

Enjoy shooting! 💚

Great Start - take further!

I really like this app especially that it creates a RAW file. I think it’s a great start. There are a couple of features that need to be added or improved. In a similar fashion as Slow Shutter App, I would love to see a feature where I can save a capture, but keep it active so I can continue to add to the exposure. This is needed for light painting where exposures can be 30 minutes or longer and you want to keep adding light but at some point you over cook it. That’s where a previous save comes in. Your interim Results feature is good for relatively short exposures, but not workable for very long exposures where the user is using the screen to judge exposure. Also the screen representation of the exposure is not keeping up with the progress fast enough to judge exposure.

Also a setting where the phone volume control can trigger the shutter is needed. This is the means by which a Bluetooth shutter remote triggers the shutter. Again most of the other camera apps have this.

Thank you for your consideration of these improvements.

Developer Response ,

Dear Bob,

Thank you for taking the time to review ReeXpose. We appreciate your feedback and are glad to hear that you like the app, especially its RAW capabilities - something quite unique on the App Store at the moment (FYI Slow Shutter Cam app does not offer Bayer RAW format but only shoots in JPG).

Regarding your comments on features that need to be added or improved, we would like to clarify that ReeXpose already offers an Interims Results feature that allows taking intermediate photos during a long capture. This feature is designed to address the specific need you mentioned for light painting/Light Trails (but also Motion Blur), and we believe it does work well even for longer exposures, so above 30 min.

As for your suggestion for a feature that allows saving a capture and keeping it active to add to the exposure, we’ll into this as this could be something we’d be interested to implement. The current Interims Results feature provides a similar functionality to that. However, we understand that there may be different workflows and needs for different users, and we appreciate your input.

Regarding your observation on "the screen representation of the exposure not keeping up with the progress fast enough to judge exposure", that's intrinsic part of the capture workflow when shooting in Bayer RAW format - meaning: what you see on screen is not what you get as an output, since the live-preview representation of the long exposure is based on the elaborated output (JPG) as the Bayer RAW is not currently representable on screen.

We are however working on an innovative solution to represent the actual Bayer RAW image instead of the elaborated JPG, with the live-preview. We want to however highlight that this is actually not present on any other app in the App Store and will take us some time to implement.

Finally, we would like to mention that ReeXpose already offers volume toggle and bluetooth shutter controls, and moreover the app provides Apple Watch integration for remote shutter, as well as the Lock Screen Widget for quick access.

You can find more info on how to use such features in our FAQ:

Thank you again for your feedback, and please do not hesitate to contact us if you have any further questions or suggestions.

Super easy to create long exposure

ReeHeld app is a photography app that has made my long exposure photos easier and more enjoyable. Usually a complex process for people that are not familiar with long exposure photography.

Well worth paying for, one of the standout features of the ReeHeld app is its s simplicity. It is easy to use and has a straightforward interface, making it accessible to users of all skill levels.

The app offers a variety of exposure times, ranging from 5 second to 30 seconds, allowing users to capture stunning long exposure shots of a range of subjects. Another great feature of the this app is its ability to save the shot straight into the photos app after taking it.

Overall, the Long Exposure app is a great tool for anyone interested in long exposure photography. Its simplicity, ease of use, and range of features make it a great choice for both beginners and more experienced photographers alike.
