To start, I just want to say that I freaking love LRTimelapse
It's always been very very good to me, and I to it (usually, haha)
Anyway, I've recently been having some issues with the Holy Grail Wizard's compensation levels in the visual workflow for some rather large sequences (2200+ images)--instead of sort of mirroring the preview lum as you might usually expect, there are two areas (transition from day to night and transition from night to day) where the compensation levels go overboard and darken the first sunset frames to almost black and brighten first sunrise frames to almost white

I have not yet pinpointed the issue (which is why I'm coming here, haha)--I used GBTimelapse to bulb ramp my camera (an SL1). What is interesting to note, however, is that I seem to only have these problems when my camera was in bulb mode during shooting; everything worked perfectly in a similar shoot in which I instructed GBTimelapse to just use preset shutter speeds instead of calculating it's own shutter speed (i.e., 20" vs 20.7" and 30" vs 29.8"). I also set GBTimelapse to stop increasing bulb speed at 30".
Also, I'm curious--how are the HG luminance compensation levels calculated?
