    Re: TriggerTrap

    It's great that there is one shot close to the start and the one at the end are virtually the same. Typical cat behavior...

      Re: TriggerTrap

      Unfortunately the Android version of Triggertrap can't use sensors or the camera to trigger the shutter - at least not yet. There is a technical limitation of Android that messes with the audio communication used between device and Triggertrap dongle. The company us working on fixing this problem and they say they are confident it will eventually be sorted.

        [ame="http://www.youtube.com/watch?v=PaeDBsGD_Lc"]Sunrise Triggertrap time-lapse clip - YouTube[/ame]

        Here is my latest Triggertrap time-lapse clip taken this morning at sunrise (actual sunrise here in Hemel Hempstead this morning was officially 7:16). The first frame was shot at 6:49 and the final one at 7:35. A total of 549 frames were shot, at one frame every 5 seconds, amounting to roughly 22 seconds at 30 frames per second.

        The camera used was an Olympus OM-D E-M5 - and the Triggertrap was controlled using a Samsung Galaxy Note. The camera was set on Aperture Priority auto exposure mode, which explains why the brightness at the beginning (when it was visibly almost night-dark) is similar to the brightness at the end of the clip (cloudy day brightness). The moral of the story - use manual exposure set to the correct exposure either for the highlight time segment of the clip or the end of the clip. Incidentally, the 500-odd frames that constituted this clip were all adjusted in Lightroom 4 and then exported at 1920x1080 resolution and imported into Adobe Premiere Pro CS6 for assimilation into a 1080HD 30p clip in MP4 format encoded using H.264.

        Next - a sunset clip using manual exposure.

          While technically interesting, I preferred the cat...

          I believe you are right in that using manual will be the right thing to do. Setting the exposure correctly will take some considerable skill or exceptional luck.

          Out of interest, how long did all the post-processing take to get to the final output

            Re: TriggerTrap

            By far the longest part was Lightroom processing the stills - that took around half an hour. Bear in mind that every frame had tone and sharpening adjustments and a slight straightening, plus cropping to 16:9 widescreen (I forgot to set the camera to 16:9!), plus resizing. The 22 second video rendering in Premiere Pro CS6 took less than a minute - thanks to Mercury Engine Playback hardware acceleration.

              That is impressive. I take it there was batch processing / actions involved.

              I can see some good tips emerging from your experiments with this thing.

              Thank you

                Yes; basically I adjusted the most dramatic frame during the sunrise and applied the changes to all the frames in the sequence, which of course is extremely easy using the Lightroom Develop synchronisation feature. I adjusted black and white levels, lifted shadows, reduced brightness, changed clarity and saturation, contrast and sharpness, added a vignette and cropped to 16:9.

                I then exported the stills at native Full HD resolution (1920x1080) JPEGs and imported them as a video sequence into Adobe Premiere Pro CS6. I didn't even edit the clip at all in Premiere, just exported it as a 1080 30p H.264 compressed MP4 video file and uploaded to YouTube.

                  Re: TriggerTrap

                  Here is another Triggertrap time-lapse clip, this time using the time warp option to decelerate time as the video plays. In fact I added the same clip reversed to the second half of this video

                  [ame="http://www.youtube.com/watch?v=S8ekvQCOw24"]Triggertrap time warp time-lapse clip - YouTube[/ame]

                  This was shot yesterday evening in a back room in the house illuminated by just one fluorescent energy-saver lamp and I used the Olympus OM-D E-M5 with the ZD 14-35 (28-70) almost wide open at f/2.2. The shutter speed was 1/10th and ISO set to 800.

                    Re: TriggerTrap

                    Very good use of limited DoF, it gives the clip a more professional look. Easy to see why the the high spec 14-35 and other such lenses are used for this type of work and on videos.

                    I really wanted the alarm to go off and rattle it way out of frame in "real time"

                      Re: TriggerTrap

                      Triggertrap yesterday announced updates to its Mobile apps for iOS and Android. You can now use WiFi to trigger a camera - it's a bit complicated as you need a master and slave device and there are restrictions for Android devices. I am looking to install Triggertrap on an iPhone 4s to complement my Android Samsung Galaxy note.

                        On the iPhone, you will then have access to all the sensor triggers. Can't wait to see what you get up to with that...

                          Finally got Triggertrap installed on the iPhone. Will be playing with it over the weekend

                            Re: TriggerTrap

                            I have managed to trigger a camera wirelessly using the iPhone master to my Samsung Galaxy Note slave. This was using a LAN infrastructure - am investigating using a point/point hotspot arrangement.

                            More good news - the app for Triggertrap Mobile is now free. I certainly found it odd that you had to purchase an app separately from the hardware when it would only work with the proprietary hardware, so the move to make the app free is an good one in my book.

                              Now that you have it on the iPhone, all the sensor features of the iPhone should be able to trigger the camera.

                              So can you simply trigger the camera by making a call to the phone with either the triggertrap mode being sound or vibration. Surprised that Triggertrap have not incorporated "Incoming Call/Text" (or have they )

                              Can't wait to see if you can capture a "Startled Cat" expression with this thing. Nothing cruel of course, but a cats curiosity is just begging to be exploited...

                                Here is the setup - OM-D E-M5 on a tripod in front of the bird feeder. The Triggertrap dongle connects the audio port on the smartphone (my Samsung Galaxy Note in its protective case taped to the tripod) to the USB port on the camera. The Galaxy Note acts as a slave to an iPhone 4s which is the Triggertrap master used to trigger the camera via the Galaxy Note. The wireless connection was over a point/point connection with the iPhone set as a mobile hotspot and the remote distance in this example was about 20 feet.

                                And here is a resulting image:



                                Of course for most of the time this is all we got to see:
