My First Time Lapse...kind of?
Hey everyone, so I did my first time lapse kind of went into it with little to no info...everytime I asked someone it seemed to be the worlds 2nd largest secret. lol... Anywho... I set my remote at a 7second delay and shutter was at 30, and f-stop at 2.8 and I used my 24-70mm I used a street corner from a hotel room window... Need corner in Philly...
Anyways, I wanted to know why when I cram the 3hrs worth of pictures it looks jittery I changed them to :01 second time... Any help? Thanks, Ryan McHugh PS Im using CS5 |

did you have your camera set to autofocus?

The camera kept focusing on a new object every time the remote released the shutter. Do a time lapse again with autofocus off and it should be smooth :)

I don't see how that could be the case, but try that too. Don't change both at the same time though because then you wouldn't be able to learn which one was your problem..
Try a time lapse of with the auto focus off, then half way through turn autofocus back on and change your shutter.

With my experience doing time lapse films I have learned a few things. Principally you can't have any automatic settings.
Auto-exposure will show in annoying detail that there are noticeable exposure differences even with 1/3 stop exposure resolution. The time lapse will appear to flicker as the camera switches between adjacent 1/3 exposure stops. You have already seen the effects of auto-focus which will show most lenses tend to slightly zoom as focus is adjusted. This creates a jittery time lapse. Of course a tripod is absolutely necessary as well. My $.02 |

timelapse.org
Hi Ryan
It doesn't have to be a secret. Go to timelapse.org | an open site for sharing all things timelapse - there is a forum there and in it you will find subtopics on all kinds of timelapse challenges from star photography, to slow and fast moving clouds, people, streetscapes, sunsets, etc. Sorry editing here the one I was trying to think of is http://www.timescapes.org/ - the other site looks very new and is just getting started. All the settings are there - from intervals, ISO, Aperture and shutterspeed. Even HDR timelapse. The main tip I have is interval is critical to smooth movelement. You need fast card to shoot smooth fast clouds on RAW. My Kingston Elite card while fast enough for video takes 2 seconds to write a RAW file. So for most things that is ok until I want to get smooth movement in fast moving clouds or people which need a 1 second interval (not the 3 I can shoot with the Kingston Elite card). I am planning to get a fast 'Ultra' type card so that I can smooth out fast moving object with 1 second intervals. The tip you got on shutter speed was perhaps from someone thinking about video and I think they are half correct. To get smooth video from a DSLR you need a shutter speed that is appropriate to your frame rate. However if you think of timelapse the equivalent of shutter speed to video is the interval between your frames. Movement will be jittery if you leave too long between takes (ie: interval). 7 seconds is way long for the people and cars your shooting out of your hotel window. It's even too long for clouds on a windy day. But would be fine for stars or slow clouds. A car will travel accross an intersection in 7 seconds so your missing a lot of the action - you will need a 1 second interval for cars and people in a streetscape (Unless its night and you want to blur the car lights). Hope this helps. Alll the best. Regards Jeff |

I vary the interval vary depending on field of view, the amount of movement within the composition and the amount of screen time I need. On a wide shot one frame every 15-20 seconds is usually enough, even one frame a minute can work perfectly well. |

There are ways to limit flicker when shooting in AV mode and there are ways to get rid of some flicker, but I'd still advise the OP to start off using manual mode for everything. |
