Hi, just upgraded to Canon 1.1.6 with magiclantern-Nightly.2016Oct09.6D116.zip and went for timelapse shooting using Silent Images. I have the following notes gathered together as requests for future development.
1) Full Sized DNGs have no EXIF data, specifically No date-time, aperture, ISO, WB value, Shutter Speed, wrong Dimensions, Date Taken (I believe all of these can be gathered from the current camera state settings in LiveView). Without White Balance and ISO data I cannot apply correct Sharpening.
2) When a DUALISO picture is taken with Silent Picture Full Sized in DNG there are 5 lines at the bottom of the frame that are not blended correctly when I convert the (renamed Dual ISO CR2 to half resolution DNG). I can provide the converter I use or please suggest another one if you feel it's a converter issue. Other Dual ISO images shot with normal procedure and converted in the same way have no issues.
3) I could not use Av or Tv for Timelapse nor Auto ISO with Silent Pictures causing the Light and AutoWB to be inconsistent as the time goes by and I am shooting Blue Hour. A workaround on-the-spot is to set the WB manually and note down on a piece of paper all settings so I know which settings were used (not practical).
4) When using Silent images the LV pre-shooting picture is about 3 stops darker than the exposure shot in Silent Pictures causing the image to be brighter. Shot time is between 15 seconds and 1 second and the LV image is always different in exposure than the image shot. You need trial and error to estimate correctly the exposure.
5) Colors are faded out (can be corrected in Post Processing) and shots are not shown correctly in camera.
6) When using Silent images there's no way to start the exposure without creating camera shake. If a programmable delay was implemented (e.g. 3 seconds) problem would be solved.
7) Silent Images faster that 1 second (I know it had been discussed before, just mentioning it)
8) (Not timelapse related) When a long exposure is taken in Bulb mode in the dark there's not way to see time passing on top LCD or in camera display.
