Post Looking for some advice with day to night timelapse
Hi all,

I picked up a little bramper a couple of years ago and it sat in the box untouched. Recently I've been getting out and experimenting with it playing with bulb ramping with sunset to night shoots and using LRTimelapse to compile. Lots of fun but I'm struggling a little in terms of getting the exposure and transition right. Generally what is your work flow when shooting a sunrise to night timelapse? Is bramping the best way to do it or do others use AV and deflicker in post?

One thing I'm yet to try with the littlebramper is its ability to ramp the ISO. Will changing the ISO on camera create unintentional shake on the camera? What are the pro's and con's in using this method?

I've only been out twice and these were the results using the little bramper. Towards the end of the timelapse the traffic just becomes a light trail mess as the exposure ramps up to around 15-20 seconds per shot which isn't ideal. Preferably I'd like to keep the exposure down at this point which I'm assuming is where ISO ramping becomes helpful?

Appreciate any feedback or tips.

What camera are you using?

If you have Canon DSLR you might consider Magic Lantern and it's automatic ETTR, you can limit the maximum shutter length and it will use ISO to compensate. It's settings are not that easy to understand at first, but there are couple good manuals out there. I wrote a short article explaining what it is - http://ansius.lv/ettr/, and there are some good links to read http://wiki.magiclantern.fm/ettr and http://www.magiclantern.fm/forum/index.php?topic=5693.0

Tough you will need to deflicker the images: in ML case there is so called deflicker module, that generates xmp files with compensation and you can deflicker also with a script in adobe bridge / camera raw http://davidmilligan.github.io/BridgeRamp/
