time lapse..
not time laps.
(will make research a lot easier!
I have tried some..plants growing over several days/weeks, that kind of thing.
any regular camera will do, (unless you need the camera to take its own pictures by itself.)
lets say you want to make a time lapse movie of your VFT growing over a 2 week span.
the main concern will be keeping the camera and the pot REALLY rooted in place..you dont want them to move, in relation to each other, at all.
the only thing that should move is the plant, as it grows.
I would nail the pot to a board, then put a tripod screw into the *same* board, so that the camera and the pot are physically connected by the plank of wood..glue some other boards around the camera, sealing it into a little wooden shell for the duration...make that camera and pot as immobile as humanly possible
.
indoors, controlled lighting, would be best, (and you wouldnt have to worry about your camera getting rained on.)
take one frame a day, or two a day, or three..whatever works for you.
if its indoors, your lighting angles wont change during the day like it would outdoors...after a week or three or 20, take all your frames and put them together into a movie! (there are programs to do that..)
thats the basic concept..biggest issues are SUPER steady camera, you dont want it to move at all, and consistant light is good too.
