I want to take a wide-angle (24 mm or so) timelapse of the Solar Eclipse in August (in the US). Does anybody have experience how to use qDSLRDashboard for that?
A couple of thoughts:
With a (ultra-)wide angle, I won't need a filter
Light difference won't be has high as day/night
Brightness change will be faster (especially at total eclipse) - should I not use average of three images for adjustments, but just one?
Usually I take images every 30 seconds, here I want to use shorter frequency
I won't need exposures as long as for night photography - does anybody know how to measure/simulate brightness during totality
I took a time-lapse of Venus transit past the sun.
you really don't need a qDSLR.
I just go my setting right, and then let a time-lapse start with Apurture for Canon.
However, The same should work for Total Solar Eclipse also,
Because if the exposure keeps opening as sun gets blocked out, the edges will start to get washed out.
So my suggestion, Click the sun till you get a good image, and then just let the time-lapse go through untouched.
I've been experimenting with it and for a totality that lasts around 2 minutes qdslrDashboard doesn't seem to adjust from day to night as quickly as it needs to. I've also set it on the minimum average not 3, and maximized the EV jump to 2 stops.
I suspect it will have to go from something in the area of 1/60, f8, 400ISO to 5 secs, f1.4, 1600 ISO to get the transition.
I was curious about Interval Timer Ramping Modes, since all I was experimenting with was the default Linear setting and not some of the exotic ones listed like quad, cube, sine, etc. Does anyone know if there's an explanation of those somewhere?
As for Ram's suggestions, are you saying that if you open the exposure during totality that the corona will wash out the edges of the sun, or did you mean something else?
