If you've been paying attention, you would have noticed that the newest update of the Triggertrap Mobile App has finally been accepted by Apple, and is now available on your iPhone, iPad and iPod Touch through an App Store app update. Version 1.1.0 fixes some small bugs and has some behind the scenes code tweaking. Most importantly, however, it introduces a brand new feature which makes the app a lot easier to use, especially if you're not particularly interested in playing with the channel output settings, and just want it to work perfectly straight out of the box.
Now, if you go into the settings (by clicking the icon of the three sliders in the top right hand corner of the main page), you are presented with a choice of presets, depending on the camera you are using with the app and the dongle.
These presets automatically set the values for the two output channel properties: Delay before trigger, Trigger pulse length, Shutter lag and Delay after trigger. We've tested tonnes of different cameras and determined the settings that work best with each, so that you don't have to.
Of course, if you want to change the settings for some more experimental uses of the app, you can still customise as much as you want or need - and if you can't remember what works, you've got your presets to fall back on to get things to work again quickly!
Automatic vs Manual Focus settings
If you take a closer look, you'll note that we have settings for both automatic and manual focus settings. We strongly recommend you shoot in manual focus.
There are a two main reasons for this:
- In automatic focus mode, you are introducing a 0.85 second delay in your photos, because we need to give the camera time to focus properly. In manual focus, your camera triggers right away.
- In automatic focus mode, you are trusting the camera's ability to focus 100%. If it turns out it doesn't focus exactly as you planned, you may come back to hundreds of out-of-focus photos. In manual focus, you can check your focus before you start the triggering programme, which means that you know in advance how the focus is set, avoiding nasty surprises.
