LRTimelapse Forum

Hello,

I just shot a timelapse of Grace Cathedral in S.F and it worked really well. I had it set to f/8 (to make sure I had deep focus), ISO 800 and 1/100 shutter speed. Everything worked until it got dark; I was able to crank it up in post production but I think it might be easier to change the exposure as it becomes darker.

My question is, is it wise to attempt to change the exposure and ISO while the camera is still shooting the time-lapse? I am scared that while I am changing the settings the tripod may move a few millimeters and change the position of the shot. I wanted to see if anyone has any recommendations for changing settings while the time-lapse is in process.

Thanks!

Hi Walter

I shoot multiple exposure for 95% of my commercial photography, and that means that having a steady tripod is vital.
I used to use a Canon 5DII, and I'd have to adjust the shutter speed by turning the dial, I'd just be very gentle - it works fine provided you have a good sturdy tripod.

I also do that in my time lapse sequences, and again, I've had no issues, just be gentle and you should be fine.

Good luck

Hamish

Thanks Hamish. I am going to shoot another one tonight and see how it works out.

hi walter
I found the same problem, how to change the exposure or ISO values without moving the camera

I am looking for a remote control that permits bramping or exposure ramping

for canon looks pretty easy but for nikon semms very compicated
i found these options, but i didnt try any

If any of you have tried one of this or knows a better system, please let me know

i do this on my setup as well, holding the pause on my emotimo while it's shooting, adjusting the exposure quickly and gently then releasing the pause as soon as the camera is settled.

It takes a bit of practice but you can manage this easily in 2 seconds or less if you can pause with a single button.

It didn't show on the footage that you miss a second or may be you have to know it's missing and watch closely.

Have you checked out the Promote Control?

It's Canon and Nikon friendly. I haven't used mine enough to give it a rating but I think it's a pretty good solution.

My cameras are set at A (aperture) priority f11.
I give it +1/3 stop exposure on the camera.
Set the focus to manual and tape the lens up.
Plug it in to the mains electrics.
Put a plastic bag over it tape it up and set the intervalometer to fire every 2 minutes then I walk away from it for 30 days.
The cameras are on Manfrotto 3D heads on Manfrotto Super Clamps and I clamp it as tight as possible.
As the camera is set on aperture priority the camera sorts out the exposure itself.

I don't touch the camera as I really don't like shaky time laps and I try to eliminate any potential sources of movement if possible.
I use Nikon D200 bodies all the time. I tried a Canon 5D mkII but I couldn't get it to behave.

I'm halfway through a 3 year time lapse in London and this is what works for me.

I might be missing something, but why do you want to start messing with the controls half way through a great sequence?
