ich habe aus zwei verschiedenen Skripten ein Timelapse Skript geschaffen, was sowohl einfache Timelapse Aufnahmen machen kann, als auch HDR Timelapse mit der Serienbildfunktion der Kamera. Das heißt, sofern die Kamera eine schnelle Serienbildfunktion besitzt, sind sehr schnell aufeinander folgende Belichtungsreihen möglich, was ein kleines Intervall der Timelapse ermöglicht. Die folgenden beiden Skripte habe ich kombiniert:
1. http://chdk.wikia.com/wiki/Lua/Scripts: ... _pre-focus
2. viewtopic.php?t=1006
Aufgrund meiner noch sehr geringen Kenntnisse über alle speziellen Funktionen von CHDK und der grundlegenden Funktionsabfolge der Kamera, ist dieses Skript lediglich aus den beiden anderen kombiniert. Einzige Ausnahme ist der Einbau der 10tel Sekunden Abstufung. Der komplette Dank geht an die Entwickler der oben genannten Skripte.
Allerdings ist es nicht für jeden möglich, einfach zwei Skripte zu kombinieren, denn auch dazu gehört ein wenig Erfahrung. Deswegen habe ich mir gedacht, teile ich mein Skript mit euch. Vielleicht kann der ein oder andere etwas damit Anfangen. Besonders Vorteilhaft ist das Skript für alle Kameras, die eine Highspeed Serienbildfunktion besitzen. Dieses bietet große Geschwindigkeitsvorteile gegenüber dem Custom Timer der originalen Firmware.
Um die Funktionen des Skripts komplett zu verstehen, empfehle ich euch den Artikel im Wiki des ersten Skriptes zu lesen (http://chdk.wikia.com/wiki/Lua/Scripts: ... _pre-focus). Folgende Einstellungen bietet mein fertiges Skript:
- Secs/frame: Alle wieviele Sekunden soll ein Bild gemacht werden?
- 10thSecs/frame: Zur Einstellung des Intervalls auf 10tel Sekunden genau. Somit sind Intervalle von z.B. 2,5 Sekunden möglich
- Sequence hours: Wieviele Stunden soll eure Aufnahme gehen
- Sequence minutes: Wieviele Minuten soll eure Aufnahme gehen (Wird zu den Stunden addiert)
- HDR img amout: Ist dieser Wert auf 0, ist der HDR Modus deaktiviert. Ansonsten werden soviele Bilder in Serie geschossen, wie hier eingestellt wurde. Beachte: Hierzu muss der Serienbild-Modus der Kamera aktiv sein, sonst kommt hier eine entsprechende Meldung! Und außerdem muss die Reihe unter Reihe im fortlauf. Modus bei Extra-Foto-Einstellungen aktiviert werden.
- Endless?: Soll die Aufnahme endlos sein? 0 = Nein, 1 = Ja. Beachte: Der Endlosmodus ist mit Vorsicht zu genießen.
- Focus: 0 = Jedes mal, 1 = Am Anfang. Je nach Auswahl wird entweder einmal zu beginn der Belichtungsreihe Fokusiert, oder vor jeder Aufnahme
Display off frame: Nach wievielen Bildern soll das Display ausgeschaltet werden. Ist allerdings nicht bei jeder Kamera komplett möglich. 0 = Nie ausschalten
Ich selbst besitze eine SX220 HS und habe deswegen das Intervall Skript für die SX-Reihe genommen. Wenn bei euch das Ausschalten des Displays bei anderen Modellen nicht funktionieren sollte, muss das andere Skript genommen werden. Wenn ihr mir das mitteilt, kann ich es gerne anpassen.
Da aber auch für den Autofocus eine andere "property number" Verwendet wurde, habe ich hier direkt einmal 2 Versionen des Skripts bereitgestellt, auch wenn die beiden sich nur in der Zahl 18 und 67 unterscheiden. Die mit der Zahl 18 für die SX Reihe, die mit der anderen Zahl für alle anderen Reihen. Ich habe rudis Verbesserungsvorschlag befolgt. Jetzt gibt es nur noch ein Skript, was in allen Kameras funktionieren sollte. Danke rudi!
Ich konnte das Skript bis jetzt nur mit meiner SX220 HS testen, auf der es einwandfrei Funktioniert (nur die Display abschalten Funktion habe ich nicht getestet). Habe das Skript aber bereits einem Kollegen gegeben, der es auf der S3 IS testen wird und mir entsprechend Feedback geben wird.
Hier die Version des Skripts, einfach als hdrtl.lua (hdrtl kann durch einen beliebigen Namen ersetzt werden) speichern und in den CHDK/SCRIPTS Ordner eurer Kamera kopieren:

Added features:
- a 10th seconds parameter for the interval to allow more precise settings
- HDR img amout: This is the amount of image the script should take every intervall. To use this function you have to switch the mode of your camera to the continuous mode.
- Sunset mode: scripts increases the tv slower than it's getting darker. this will make a reel sunset feeling in the timelapse
Important:
For a real HDR Timelapse you have to activate the Bracketing in Continuous Mode in the Extra Photo Operations and set the Bracketing type and value to any of your choice in addition.
This Script is a modifcation of the Accurate Intervalometer with power-saving and pre-focus Script and the Turbo-Intervall Script.

Author: Fraser McCrossan
Modification for SX100 IS: Anar Ibragimoff
An accurate intervalometer script, with pre-focus and screen power off options.
Features:
- input is frame interval plus total desired run-time (or "endless")
- displays frame count, frame total and remaining time after each frame
(in endless mode, displays frame count and elapsed time)
- honours the "Print" button during frame delays (so you can
get it running then turn off the display to save power)
- can turn off the display a given number of frames after starting
(might take a couple of frames longer to cycle to correct mode)
- can pre-focus before starting then go to manual focus mode
- use SET button to exit
Additional notes:
- To use "display off" feature, you need to configure your camera
to turn display off on "Print" button (in standard camera's menu)
- For additional power save I'd recommend to turn off preview after shoots (in standard camera's menu)
