Sicherlich ist die einfachste und schnellste Lösung, eine Belichtungsreihe zu erstellen, schon im CHDK eingebaut. Es gibt aber immer wieder Anwendungen, bei den besondere Einstellungen erwünscht sind. Dieses Skript faßt diese Möglichkeiten zusammen.
Für das Skript ist eine aktuelle CHDK-Version notwendig. Es sollte auf allen Kameras laufen.
Belichtungsreihe als Ev-Reihe oder Tv-Reihe alternierend
Mehrfache Erstellung von Bildern in einer Einstellung - wichtig bei Langzeitbelichtung.
Fixierung Fokus
Log-Datei schreiben
Skript-Parameter
Schrittweite in 1/3 Ev oder 1 Tv: voreingestellt 3
Anzahl verschiedene Werte: voreingestellt 5
Startverzögerung in s: voreingestellt 1s
Anzahl Bilder pro Wert: voreingestellt 1
Fix Fokus 0=aus 1=an: voreingestellt an
Modus 0=Ev 1=Tv: voreingestellt Ev
Log -1=aus ab 0 Dateiname: voreingestellt 0
Die Log-Datei befindet sich im CHDK-Unterverzeichnis LOG und hat den Namen LOG_0100.txt bei Voreinstellung 0. Ändert man den Voreinstellwert 0 auf z.B. 5, heißt die Datei LOG_0105.txt. Sie enthält alle Informationen, die in Skriptkonsole angezeigt wurden. Somit ist eine spätere Zuordnung der Bilder einfacher möglich.
