Timelapse+ is a new intervalometer development project on Kickstarter. Elijah Parker in Minneapolis, MN is working on producing a pretty powerful all-in-one intervalometer for DSLR cameras that's completely open source.
So you've just scoured your camera's manual and sifted through the extensive menu system and alas, no built in intervalometer. That's ok, an external timer remote for your camera is lot less expensive than you think. Well, some of them are. That's the purpose of this post is to layout some of the options that exist when looking for an external intervalometer for DSLR time-lapse photography.
