This thursday i have been asked to do a all day timelapse of a 2200 people group photo, only problem is, i am in the photo. The timelapse does not strictly need to be at set intervals (IE: I dont NEED 1 photo every 20 secs they can be random) Only problem is it will be 3 hours either side of a 10 min photo taking sesion while everyone gets into formation and out of formation. So my 2 options are as folows:
The camera i will be using is a Canon 1DMkII with a 24-70 f2.8 set at about f11 so focus isnt tooo critical.
1) Using my TC80N3 set the pics to be taken every 15 seconds, great untill it comes to the 5 photos they take in the middle of the group, im worried i might miss the critical centre peice being the formal full photo and get the moments on either end where people are slouched over or talking etc
2) Using my pocket wizards and a PreTrigger cable i can personal take the photos, only problem being they wont be set at exact intervals if that is a problem, one way i can think of around that is if there was a Timer Control for the rebel series which could plug into the miniphone plug on the PWs.
Thanks
