5DMKII Bulb Ramping large exposure jumps
« on: August 18, 2014, 05:04:34 AM »
Hey all,

let me first start this by saying i'm a noob.  Apologies up front, but i'm seeing something odd so I figured i'd ask.  I tried using bulb ramping today

Here's the setup:

Camera is a 5DMKII
I started f/11 1/80 ISO 100. 

I was shooting on M with no ND filter.  ML was set to intervalometer and BRamping (set to sunet).

the first 78 exposures seemed to work just fine. Exposure 78 was at 1.60.  Exposure 79 jumped to 1/20.  The next big jump happened at exposure 125.  The exposure at 124 was 1/20.  The exposure time at 125 was 1/5.  I'm not quite sure what I'm doing wrong here.  I know i must have done something wrong, but it's not jumping out at me.  Would appreciate a pointer in the right direction.

bulb ramping was removed from ML in favor of a better method:

If you want to use what dmilligan posted a link to than yes, you need a Nightly Build and to download the Module in the link then add to the module folder of newly downloaded files after extraction...
