I also use the hähnel Giga T Pro II, you can use it as a timer and intervalometer and wired or wireless.
As intervallometer you can progam a program for lets say 10 shots per minute and then embed this progam in a 2nd progam so it repeats progam 1 every 5 min.
I think this makes it perfect for time lapses.
It is expensive but it can do every thing you would want.
This seems like a huge advantage over regular intervalometers. I struggle to imagine what it would look like though. Can you show me the effect his double loop has in time lapse videos?
I haven't used the double loop it yet.
but it could be very useful if you want to make a time laps video of 1 place of a whole day but lets say you want too get a sequence of x frames during y min shot in the morning, x frames a few hours later and so on.
Then you get a video of x/24 min morning + x/24 min midday + x/24 min afternoon + x/24 min evening.
Or if you want to capture an action time laps, for example of cars driving on a circuit, you know they pass every 5 min and they pass in 5 sec then you can program for example 8 frames per sec during 5 sec and repeat it every 5 min.
Or if you want to have startrails that are like a dotted lines(- - - - -) if you know what I mean.
