Post 12 Hour Timelapse Job SOON ;/
Hey all!

I just joined and this is my first post! ! Great to be here.

pardon my hurried request ~ first, a little about my background. I've done photography casually for about 5 years now. Weddings, portraits, etc. I take on gigs as they come up, not too often but I like it and I learn as I go. I've done several timelapses and someone emailed someone and I got an offer to do one for a construction company so I figured I'd give it a try.

I am familiar with ML and have done some bulb ramping. I have used gbtimelapse and gbdeflicker and my intervalometer for simple daytime timelapse.

My Project: 5am - 5pm. Dark, to light, to dark again. :/ They are moving a bunch of stuff from the top of a building (HVAC company) and I am shooting this from 3 cameras :

1. GoPro Hero 3+ black at image every 5 seconds for 12 hours.
2. Canon t1i with ML - not sure if I should use gbtimelapse or ML but welcome suggestions. Not sure on time interval. Zoomed canon 24-105 f4 lens. could use NDs
3. Canon 6D - no ML - but will probably use gbtimelapse. not sure on time interval. wide angle lens rokinon 10mm f2.8 locked at 2.8. (Not possible to use ND filter on this one)

My problem: I keep doing test shoots during various times (4am - 12pm, etc) and the flicker is bad. The TV stepping is obvious and the AV flicker at .1sec exposure with aperture at 22 gives a lot of AV flicker and it drives me crazy. I feel stuck and worried I wont be able to remove the flicker from the work that I will have to present.

Help: If anyone can offer me some help I'd be more than grateful. I feel like I can fall back to the gopro and deflicker that and I will be ok but really want to get this with the DSLR cameras.

A huge thank you for anyone that can help. Thanks. ~Ben in Portland :? 8-) :D :roll: :shock:

just to clarify ~ I am basically looking for insight if this is the correct method to proceed or if the experts have any guidance.

Today I attempted a 3FPS Video timelapse with ML on my t1i and it seems with a manual lens it messes up the shutter speed settings so it is way to bright.
I still think my best bet is to use the gopro in timelapse mode, and the 6d with gbtimelapse and toss in a ND filter once it gets to tv fluctuation mode to keep it under .1 second shutter speeds.

Thanks all for any input!

You have to use GB timelapse with your equipment.
Otherwise you will need to use something like LR Timelapse in post.

There is going to be a lot of flicker unless you lock your aperture down.
Why are you shooting at F22?

Ok. The only issue I have now is that when I let gb timelapse do any adjustment of aperture it caused bad flicker.

Can these programs (LR timelapse and gbdeflicker) remove all flicker? I just haven't had good results using gbdeflicker to remove flicker, and am ready to switch to ND filters.

I was shooting at f22 because it was so bright out it couldn't stay in bulb mode without going to high f numbers to keep exposure below .1 seconds.

Thanks for helping!

It went well folks. Not perfect, but very well given my short timeline!
