Did a time lapse of the sunset over the mountains in Colorado last night.  Chose to do 15 sec between photos (didn't think there would be enough change otherwise).  When I finished up, I ended up with a 4 second time lapse over 20 minutes of the sun setting.  Cool look, but way too short.  Is a frame a second good?  Will it have enough change?

Thanks for your input.

If you do it a frame a second you can always speed it up in post.

Thank you, I’ll do that for the next one!
