Post Delay pre and post focus pull

He Chris

I know it is possible to set a delay at the start of a lapse, but is it possible to set a delay at the start of say 60 frames, then run into a 30 second focus pull, and then into another run of say 90 frames with no further focus pull?

It sure is!

A few weeks back i released Chronotimer 1.3.4, which does include this functionality, here is an excerpt....

http://thechronosproject.com/downloads/

====================================================
2) Endless Shooting.

I do a lot of my work in Live Ramping, which will continue to fire indefinitely unless stopped.
SGO will pass the shutter through the controller, so even after the apparatus is done with its routine the camera can still be triggered.

However, if you are using the Chronocontroller as the main timing source, and you setup a 200 shot lead in, with a 60 frame focus or zoom adjustment, when it is done it is done. There were no Lead-Outs that could be done.

Endless shooting fixes that, and allows shooters to use the Controller as the primary timing source and will allow shooting after the routine has finished

A quick revisit to DEL. WHen using DEL you are setting a delay before the system runs its movements.

if you have a SHOT of 500, with a DEL of 300, then for shots 1-300 the system will not move. All movement will happen between shots 301 through 500.

TO access the Endless Shooting you simply move to DEL, and press <- and ->
E ON = Endless shooting ON
E OFF (default) = Endless Shooting OFF.

You may remember, this used to have PASS and BLOC instead, which would allow you to pass an external shutter signal into the controller and out to the camera even if the controller was not running a routine. This PASS/BLOC is also adjustable as a default in the Calibration Menu accessed by going to POS and pressing <- and SET at the same time. It seeed redundant to have it in two locations, and i have never found the need to turn PASS off. So it is now only accessable through the Calibration Menu. The default is always ON.

==================================================
So with this in mind, if you have the 1.3.4 code you would setup as follows.

1) Setup the Keyframes using the normal procedure
2) Set the SHOT count to 90 (60 frame lead in + 30 frame focus ramp)
3) Set DEL to 60
4) While the Mode dial is in DEL, press <- or ->, you want it to display E ON.
5) Start the routine.

You will see it do nothing for the first 60 frames, it will just trigger the camera.
frames 61-90 will adjust the focus
Frames 91+ will just trigger the camera. It will continue this indefinitely.

Hey Chris. So that all worked perfectly, but as soon as the system gets to the point where it goes from 91+ frames (so the end of the programmed sequence) each exposure trigger happens twice? So instead of a single exposure as it has always been doing, it now triggers two exposures directly after one another for the interval.. Any idea whats happening here?

Hi Sorry, im not ignoring, I have been on call this week at work and they have been working me ragged.

What kind of camera?
info on settings... Shutter speed, drive mode (single shot, burst, etc)

Can you give me the basic settings you are using with Chronos?
Bulb exposure?
Interval?
etc

Ill try to recreate this tonight when i get home.

Thank you!

No worries Chris.

Not sure on the settings but from what I can remember they were as follows:

Camera on full manual for lapses.

shutter speed at 0.5 secs
aperture of 4
longer exposure accounted for in bulb mode on the chronocontroller
interval of 5 secs
Then the rest of the settings pretty much as you described in the post above.
Delay for 60 exposures
Focus pull for 30 exposures
And then endless shooting from 91+

The double exposures only happen when the endless shooting starts.

I dont have the system on me at the moment so I cant give you the exact settings but they were as they should be. No extra settings changed anywhere. I followed all your tuts very carefully and your explanation above

Im working on fixing the bug, i got the doubleshot removed, but now i'm running into another issue with a couple extra seconds of lag time between the motion shots and endless shots. Its just that one shot, but it needs to be seamless.

Ill let you know when i have it fixed

FIXED!!!!!!!

WOW that was WAY harder than it needed to be. 1.3.5 is now on the doanload page and it does fix this issue! No more doubleshots, and the transition from the motion shots to the endless shots is 100% seamless!

THANK YOU for letting me know about this bug, if you find any more dont hesitate to tell me. Its funny, i can tell nobody has been using that endless shooting feature as you are the only person to report this to me. I really do appreciate it. I hate buggy code! Sometimes something falls through my testing. I dont know how i missed this, unless my camera was set in a way where it sort of ignored the second shutter release.

Ah awesome! Thanks Chris!!

Ya am I the only one who is actually using this for lapses, it seems as there isnt much content or feedback from other users on the forum at all.

Anyways, thanks for your help, I'll feedback anything I find along the way forsure!
