Triggertrap releases mobile app for iPhone-controlled cable release

By dpreview staff on Apr 30, 2012 at 17:00 GMT

Triggertrap has announced a mobile app that converts your iPhone into a highly-configurable remote release for your camera. It works in concert with two hardware components, a Mobile Dongle that connects to the phone plus a suitable camera cable, to offer a wide range of methods to release the shutter. These include timelapse, distance lapse (based upon the phone's GPS), face recognition, and sound, motion, and shock detectors. It can also control High Dynamic Range bracketing up to 19 exposures. A free trial version of the app is available for evaluation purposes. The full app and Mobile Dongle each cost $9.99, and are available now from the iTune App Store and Triggertrap web shop respectively.

The Triggertrap Mobile app and dongle allow several sophisticated triggering modes, including a system that shortens the intervals as a time-lapse sequence progresses, or shortens them as it ends. This gives a speeding-up or slowing-down effect when the sequence is replayed. The character of these ramps can be adjusted, too.

A free version of the app, with three of the full app's features, is also available.


Press release:

LONDON, 30 APRIL 2012: With a dozen different ways of triggering your digital SLR camera from your iPhone, the Triggertrap Mobile app takes creative photography to a new level.

By combining the success from their previous two products – the Kickstarter-funded Triggertrap v1 and Triggertrap Shield for Arduino – the Triggertrap team are announcing a brand new product today; Triggertrap Mobile.

The Triggertrap Mobile app can be used on its own, in which case it triggers the iPhone’s internal camera, but its innovation really shines when you use the Triggertrap Mobile Dongle to connect your phone to your SLR or advanced compact camera.

Introduction Video:

Never-Before Seen Ways Of Triggering Your Camera

With the Triggertrap Mobile App, users can use the world around them to trigger their cameras in lots of innovative ways. Most photographers are familiar with Time-lapse photography (which is also built in), but the Triggertrap Mobile App introduces several triggering mechanisms that have never before been seen in a consumer device:

Distance-Lapse enables the user to set up a camera to take a photo at regular distance-intervals (every 100 meters, for example). When they are assembled into a movie, it appears as if the entire journey was conducted at exactly the same pace. When driving on a highway, for example, the app would take photos more quickly as the journey progresses at speed, and more slowly when the driver gets stuck in traffic. If you stop for a break, the Triggertrap Mobile App knows, and simply stops taking photos whilst the car is stopped.

 The app offers several modes
including sound sensitivity
And 'eased' timelapse that
'ramps-up' or down the
beginning or end of a timelapse
sequence.

Eased Timelapse is the other huge innovation in the Triggertrap Mobile app. When doing a traditional time-lapse, a user would choose to take a photo, say, every 10 seconds. In Eased Timelapse, however, the Triggertrap Mobile App uses mathematical formulas to vary the interval between photographs dynamically. The result is that, in the assembled time-lapse video, it appears as if time speeds up at the beginning of the video, and slows back down at the end – perfect for creating beautiful effects! The Triggertrap Mobile App comes with 5 acceleration profiles (ranging from ‘mild’ to ‘brutal’; or known in the animation world as ranging from Quadratic to Quintic acceleration). The user can choose whether they wish to ease in, out, or both.

12 Different Triggering Modes

In addition to the already mentioned Timelapse, Eased Timelapse and Distance-Lapse mode, the Triggertrap Mobile App has a load of other triggering modes built in, including facial recognition, a shock sensor, a motion sensor, a magnetometer, a sound sensor, automatic High Dynamic Range (HDR) bracketing with up to 19 exposures per set and configurable steps between each exposure, a HDR timelapse mode and Star Trail photography mode.

Finally the Triggertrap Mobile App has a Cable Release mode, which enables users to use the app as a traditional wired remote control, complete with Bulb mode (hold the button for long exposures), Timed Bulb mode (press the button to start an exposure, press it again to finish), Long Exposure mode (the user can select any exposure from one second to 60 minutes, and the app will trigger the user’s camera for that duration), and much, much more.

3 Different Shutter Channels

The Triggertrap Mobile Dongle supports two different devices – usually configured as the focus and shutter on a SLR camera.

For advanced users, the channels can be renamed to whatever the user wants, and all channel settings can be configured independently of each other. By using different cables or adapters, it’s possible to use the Triggertrap Mobile App to trigger just a camera, a camera and a flash separately, or even two independent flashes.

The TriggerTrap Mobile Dongle

Each ‘channel’ can be configured with a number of settings, including the delay before triggering, a delay after triggering (to limit the number of photos taken in rapid succession) and a shutter lag compensation. The Triggertrap Mobile App also offers a customisable ‘shutter pulse length’ – or the duration of the signal sent to the channel. For a flash, this can be very short (typically 20 ms), for a camera shutter, this needs to be a little bit longer (typically 150ms), and it can be configured to be much longer, to give the camera connected to the Triggertrap Mobile App enough time to focus.

The Triggertrap Mobile App comes with a Lag-o-meter built in, which is designed to measure the shutter lag on your camera. This is important, for example, if the user wants to utilise the built-in bulb or HDR modes. Shutter lag could cause discrepancies in the exposures in these situation; the Lag-o-meter and the built-in shutter lag compensation settings solve the problem.

The final ‘channel’ is the camera built into iOS devices, which can be used with many of the Triggertrap Mobile App triggers.

Free Trial Version

In addition to the $9.99 (or local equivalent) premium version of the application, Triggertrap is also releasing Triggertrap Free, which is available as a trial version.

The Free app includes three full modes from the Premium version of the app: Cable Release mode, Timelapse, and the Seismic mode, which uses the iPhone’s acceleration sensors to trigger the camera based on vibrations, bumps, or knocks.

Pricing And Availability

The Triggertrap Mobile App is available in the iTunes App Store (http://j.mp/tt-mobile) from 30 April 2012, and will cost $9.99 (or equivalent in local markets).

The Triggertrap Mobile App (FREE) is available in the iTunes App Store (http://j.mp/tt-free) from 30 April 2012.

The Triggertrap Mobile Dongle is available now, costs $9.99 and is available from the Triggertrap web shop on http://triggertrap.com/dongle . Camera connection cables are also available from the same site.

"Never seen before features"? Sorry, but I've had most of those features with the software that came with even my old 400D.

I post comment on iTune with few suggestions.....they where remove fast!

The idea is great, but the user interface is not good in the field.

It's difficult to set exact value with the small slider....Some label are to small for reading....they should review the UI....

Really nice. Now, all our modern camera have the computing power and the devices to do something like that in-camera. I can't understand, really, why firmware in DSLRs are still in the age of DOS. When do someone wake up and add "apps" to their cameras?

Yes, it would require very little firmware to enable a camera to do all this. But would it yield any returns if the manufacturers could charge only an additional $9.99 and consumers ignored the feature, preferring higher megapixel count above all?

I'm positive it will be a strong selling point, if well done. Think for example trigger by movement, or a P-mode biased for the sweet spot of your lenses, or.... whatever. I have a list of several handy features for which I wouldn't mind paying an extra 10 or 20 euros for my A55. Extended bracketing, focus bracketing,...

There many bulb-base triggers for timelapse. They're all okay. However, I will not buy one, until they come up with a version that it triggers the canon camera via the USB where the actually exposure can be set shorter than 1/10 seconds instead of the bulb triggering.

How is the app able to change exposure settings on the camera for exposure bracketing? I'd love to be able to exposure adjust during a timelapse based on a user defined curve.

I'm gonna guess and say by changing the shutter speed, same way as my camera does when I use its exposure bracketing function.

Except the app is promising to do HDR bracketing up to 19 photos. You need access to exposure settings to do that.

Did you take the time to visit their web site? They have videos explaining all the features.
It adjusts exposure time by the length of the trigger impulse. So it is limited to shutter speed only.

By graybalanced (May 1, 2012)

And even if you were using a top-of-the-line SLR, shutter speed is the only variable you'd want to change. You don't want to change aperture, because that'll create inconsistent depth of field. You don't want to change ISO, because that would create inconsistent noise levels. So if the phone app can only control exposure through shutter speed, there's nothing wrong with that at all.

not always,
I don't like camera mess with speed settings,
speed is important, it will make sharp or blurry images,
I can deal with dof easily by selecting point of interest

this apps work in bulb mode, like octane said,
I don't think it is usefull

'Did you take the time to visit their web site? They have videos explaining all the features.'

They should have explained that in the press release. If I have to go to their website to figure out how they are doing one of their main advertised features then they didn't write the press release clearly enough.

found out lack of information on their website,
if they promote only for triggering for iOS,
that would be a waste, I got 10 meters canon trigger cable
and canon IR remote
they should inform more details on other features,
triggering is not an interesting factor

It's confusing, but it sounds like $19.95 includes both camera connector and mobile dongle - the article said $9.95 for only the mobile dongle. Doesn't make a difference if you have only one type of camera, since you need both to have it working. If you have more than one make of camera, though, you should only need additional appropriatel camera connectors.

Hey!

This is correct - it was a $9.99+$9.99 for a dongle / cable combo, but we ran into some problems with our shopping cart, so for now, we're only offering them together.

Once we fix our shopping cart, we'll go back to offering them separately!

For Android you might want to take a look at DSLR Controller for Canon cameras:

https://play.google.com/store/apps/details?id=eu.chainfire.dslrcontroller

Works fine on my Samsung Galaxy S II together with my Canon EOS 50D. Your phone/tablet must have USB Host Kernel + API support (Android 3.1+ comes with the API if the device has the kernel support). You might also need a USB Host cable, but besides that no additional hardware are required. Also see http://dslrcontroller.com/ .

@Stig: I tried the chainfire for the last two days, it has a critical flaw it tethers camera connection including the live view which means its draining the camera battery unnecessarily so I will wait for android version of trigger trap. Thanks for the reply.
