I have a Pluto Trigger, a gift from my son, and slowly I'm learning to use it. My current curiosity is how to capture lightning. The Pluto Trigger has a lightning mode where you set the sensitivity, and it's internal light sensor triggers the camera shutter each time some light event changes. Lots of false positives, but a few quite interesting photos.
Last evening we had an almost storm - i.e. dark clouds, lightning and no rain. Perfect for trying to capture lighting. I managed to capture one event in about 300 - but that event was quite interesting. Two consecutive triggers a second apart displayed the same lighting event - suggesting the duration was > 1 sec. Here are the images and its clear (at least to me) that they represent the same event - a discontinuous upper segment and the lower segment follows the tree limb. I'm shooting at ISO 100, f/8, 1/10 sec exposure.
|First event: 19:11:49 - a discontinuous top (probably hidden behind something) and the lower segment follows the tree limb|
|Second event: 19:11:50 - Same less bright, probably because the duration is less than 1/10 sec (exposure time). However this suggests the total duration of the event was > 1 sec.|
