Timelapse+ is a small intervolometer timelapseplus.com/ I like use my Canon 5DMkIII. I use Magic Lantern on my T2I but haven't been successful with getting that to Bramp using built in capabilities yet. The developer of the Timelapse + noticed some minute flickr in my first test and suggested a Bulb offset.
Of course I cringed as I'm a relatively newbie to the world of advanced timelapse. However he sent me a link to a forum post at Timelapse + that I have never visited (a wealth of information) and it offered up some straight forward ways to see if you need to do a bulb offset.
I figured why not give it a try. After checking the images I sure enough had my bulb image much brighter so I needed an offset. After a few trys I got what I thought was a perfect DNA histogram match between my test image, and bulb image on my off set image and so it was off to the races.
The run was a full 3 hour 15 sec interval. I started at beginning shutter of about 1/10 as some have reported the 5DMKIII not being able to go much higher say 1/20, but I may give mine a try. Since my first test was at 1/10 I stayed within the parameter. The night was pretty boring so I did add my little slider for some spice.
I processed in LRTtimelapse and After Effects and really liked the outcome with this test set. For such a small package thats easy to carry, set up and thats inexpensive I can get some pretty nice day to night sequences going. Some light shifts you see on the bushes may have been caused by me checking on the system during the run with a small headlamp..we do have scorpions and I didn't want to step on any that were checking out the timelapse.
