Scripting Q&A / Re: Extra delay script for intervalometer

One thought, that I haven’t tested, and @a1ex may say won’t work is that you dynamically change the intervalometer settings via the event functional call, ie use a menu.set call to change the take a picture every value to whatever number you want, ie as your TL progresses.

Just tested this:

Code: [Select]

event.intervalometer = function(count) menu.set("Intervalometer","Take a pic every",count.."s") return end
It works, ie as a ramping function, but it seems to restart the intervalometers start delay but respects the count, ie the event doesn’t appear to reset count. So, if you put the start delay to zero, you can certainly 'play around' with dynamically tweaking the TL times using the event call, ie achieve 'variable' TLs, even if you are not a Lua scripter.

Might be worth experimenting with, ie as a crude user controlled ramping approach.

I don't know what kind of signal you get through the hotshoe port, though - is it a logic signal active during the entire exposure, or something else?

The center contact is closed as long as the exposure is on. You can even measure the exposure time with it, but not very precisely. I control my dolly with the hotshoe

For this task you actually need a script with interval ramping. The lrtimelapse pro timer can do that too.

The problem is the different interval times. If the interval is more than 8s, the sunset becomes too fast. The starry sky takes about 30s. It is important for interval ramping that the transition is as smooth as possible. You should therefore not necessarily let the interval run over the exposure time. If, for example, a cloud comes in front of the sun before sunset, then the interval speed should not always change.

I wanted to do that with a CHDK lua script last year.
My idea was:

The interval starts with a fixed interval. If the exposure time comes in an order of magnitude (interval - exposure time <2s) then I would start the ramping. Perhaps I would adjust the ramping speed slightly, depending on the difference. But I would only ever increase the interval. Only when the maximum interval has been reached for a certain time could ramping be allowed to run in the other direction (For the night-day transition).

Well, it is getting some sort of complicated by the fact this implementation has its origin in KR.

By the way, ML on the EOS-M, the 100D, the 5D3 and other models too has this function already in the video mode.

Yes I know, that’s why I posted the link, as I thought some may be interested in the claim of a ‘new’ idea ;-)

@a1ex: Have you checked if KR zoom implemented by ML violates any patent granted to KR?

Thanks Walter. So what is *.DNG then? I read articles where people mentioned shooting using ML and then importing the *.Dng video clips in editing softwares.

Garry,

Please read the comments in that link. I mostly agree with them. It may help with a little bit better composition in the long end but not much more.

By the way, ML on the EOS-M, the 100D, the 5D3 and other models too has this function already in the video mode. You just press the SET button (Zoom button on the 5D3) and your camera enters 3x crop mode immediately. I find it much more convenient than using the zoom ring on a zoom lens. This works quite well with prime lenses for event videography. If I use my favorite EF 35/F2 IS lens in the 3x3 or 1x3 full sensor readout mode, it turns it into a stabilized 105 mm lens in the 1x1 mode on a push of a button and without loss of image quality.
