Exposure change during Time Lapse shooting

[GoogleCodeExporter]

Hi Zoltan,

this is not an issue, it's a question that I cannot answer myself as I have not 
yet bought a new mobile device to run your dslrdashboard to try it out myself.

While shooting a time lapse from day into night it is necessary to change the 
exposure time without interrupting the current shooting of the time lapse 
sequence. Is that possible with your dslrdashboard?

Here an idea for further development (in case you're interested).
When shooting a time lapse sequence from day into night (or the other way 
around) the available light inevitably changes. Cameras normally reflect this 
fact by showing the amount of under- / over-exposure.
Currently exposure settings must be changed manually (or in my case with my 
Arduino running a USB-Host shield doing just that).
The idea is enable a function that reads the amount of over- / under-exposure 
and then changes for example the exposure setting only if the last 5 shots have 
been under-/over-exposed by say 1 EV.
2 parameters should then be user configurable: a) the number of shots required 
to change the exposure setting b) the amount (in EV) of over-/under-exposure to 
trigger the exposure adjustment change.
This would enable exposure adjustments according to readings of the built in 
light meter in your dslrdashboard.
What do you think?

Greetings, Hans.

Hi

I was thinking to add bulb ramping for the time-lapse for the models that 
support the bulb function in PTP mode. I did some tests but didn't had yet time 
to work on it more.
There is the 'advanced timelapse' 
(https://code.google.com/p/dslrdashboard/wiki/AdvancedTimelapse) and I plan to 
extend it a bit. Your proposal is also interesting and will see if I could 
implement such a feature.
