What happens when you load in LRT, a day / night sequence, performed with 1 or more ND filters. The procedure is the same.
Thanks

It's the same, as long as you left the nd filters on all the time. If you removed them while shooting (not recommended) , it's more complicated. Please use the search feature, we already covered this here.

I am interested in the second case, I will try to search in the feature, if I do not understand I will ask for help, if there are discussions about it you can direct me.
thanks

I've explained here why it's a bad idea to change ND filters while shooting: https://forum.lrtimelapse.com/Thread-nd-...8#pid30528

I thank you for the explanation, https://forum.lrtimelapse.com/Thread-nd-...8#pid30528, tried to follow the two ways to evaluate which is the best solution in my case.
Thank you also for the availability
