Advanced Intervalometer (adv_int.mo)
This module is for advanced ramping and control of exposure parameters during an intervalometer sequence.With this module you specify the ramping by creating keyframes with the values of various parameters that you want to ramp to. When the intervalometer is running, this module ramps the specified parameter(s) from one keyframe to the next. Update: The Advanced Intervalometer menu now shows up under the Intervalometer submenu.
I think some cool effects can be done by ramping aperture (and let AutoETTR compensate the expo with Tv, ISO) and focus or a combination of the two. You could have a scene where everything is in focus with f/22 and then ramp down to f/2 to blur out everything but your subject. The video below is my first quick and dirty test of this module and does just that:
I ramped the Av from min to max and back to min, and let AutoETTR+Post Deflicker take care of the exposure.
The other potential use for Av ramping is a full day to full night (or vice versa) time-lapse, where you might want a pretty small Av during the day, and then open it all the way wide open and move to focus infinity to get the faint light of stars/milky way when it gets dark. So basically you are making the "artistic" exposure choices, with your knowledge of time of sunset/twilight, while AutoETTR takes care of then optimizing the exposure.
Here's some examples where I used Av ramping with AutoETTR:
Tv ramping could be very useful for doing some varying amounts of motion blur. Think car lights at night: by varying the shutter angle, you vary the length of the streaks of car lights. I've seen this done in timelapses, and the effect is very cool.
Changing the actual intervalometer period allows you to create accelerating or decelerating timelapses with out having to waste shutter actuations (you can easily accelerate or decelerate in post, but you will in essence be throwing out frames). Another thing you could do is to actually slow down your footage in post by the same amount you ramp the intervalometer period. This would give the effect of the time-lapse not actually chaining speed, but it would become more or less "choppy".
To use, download the latest nightly
and add this module to the ML/modules folder:https://bitbucket.org/dmilligan/magic-lantern/downloads/adv_int.mo
See the readme
for instructions on how to use.Current list of settings that can be ramped
- interval time
- bulb duration
- white balance
[2014-2-25] Updated to work with new menu features (mult-level submenus and menu_caret)
[2014-3-8] Updated to work with module version 5, Added ability to adjust Tv, Av, ISO from within adv_int menu, so you don't have to leave the menu and come backDisclaimer:
