Yes, I agree. Fantastic. That is how I would prefer it.
Overexposure and Underexposure are defaults?
Ev shift 1/4
Meter low thresh 3
Meter low limit 4
Overexp thresh% 2
Overexp Ev 1/4
Underexp thresh% 10
Underexp -Ev 5
I’m wondering that the aperture (av96) changes.
I thought the script doesn't handle aperture adjustments yet.
This is actually the ND filter, but for exposure calculation it's treated as Av. Note that the script currently supports this only on cameras that don't have an iris. On cameras like the S110 or G1X that have both, ND is currently ignored by the script.
I run the script in Av Mode. Is this OK? I have not seen any restriction.
It shouldn't matter. As far as I know, the canon firmware won't adjust settings while it's shooting. I'd stay away from weird scene modes.
When it is necessary to share more files, I will install a dropbox. Until now, I don’t have something like this.
With most of those services you can also just upload through the web site if you don't want to install the app.
When I talking about pictures against the sun, I mean sunset and sunrise, like in your last video. Of course, I always use the ND filter from the cam to protect the cam a little bit. I also check the sensor temperature in my script and make a shutdown when the temperature exceeds 59 degree. Does this make sense in your script?
That's not a bad idea, I can put in a temperature shutdown option. I've wondered how bad it is to point the sun, but I haven't seen problems yet. The sensor and optical temperature is recorded in the logs, so far I haven't seen any crazy values. FWIW, on some cameras at least the reported "sensor" temperature is somewhere on the sensor PCB, but not part of the actual image sensor chip.
The first shoots with the script have always a lot Overexposure (not seen on my plot, but it’s in the log file). After 5-10 shoots it is Ok. Can this make problems when using the first shot?
Maybe, but I don't think it should be a big problem in most cases. Since it uses absolute brightness, the exact exposure doesn't matter, but the Bv will be underestimated if the pixels in the meter area are saturated.
This is the time laps video from the test with 1% Overexposure where the overexposure increases after around picture 225 (9s on the video). May be its helpful.
It would be helpful to see the debug displays. Is this the same sequence from the log you posted earlier? It looks like quite a large area of sky is overexposed, so a larger "Overexp Ev" might help. If you don't mind having the rest of the scene dark, you could also reduce or disable under exposure protection (larger Underexp thresh% and Underexp -Ev)
I'll have a look at the drtest stuff later.
