So now I also have an S110 1.03 (!) to compare.
for underexposure and overexposure control
We'd like to have the sensitivity and exposure to go up as soon as possible when it gets dark....
I can only playing a little bit with the weight. But without the meter window, the exposure will probably not increase...
rawopint needs tweaking I guess?
What would be the reasonable settings for underexposure and overexposure control if we would do a timelapse run from dusk until dawn?Priority would be the stars, milkyway andsuch, so a whiteout of the moon is not a big issue.
For the sx260 underexposure control is turned off, is that OK for such a dusk -> dawn run?
Get your field of view. You can use this Angular Field of View Calculator with focal length in 35mm equivalent, multiplier 1 (or use actual FL and multiplier for your cam), 4:3 aspectMoon is about 1/2 degree, so Moon width in pixels = 0.5*(sensor width in pixels)/(horizontal fov).Moon pixel area roughly = width squared (yeah, I know it's round )Moon pixel area in parts per 100k = (moon area)*100,000/(sensor area)
If you want to ignore the moon, and have underexposure protection disabled, then your Overexp thresh should be larger than the moon.
From this site I get a multiplier of 4.62; combining that with a 24 mm equivalent focal length it gives me:
24 is the 35mm equivalent focal length, so if you use that the multiplier should be 1.If you use the real focal length (5.2) then the multiplier should be 4.62 ( = 24/5.2 for this camera), and you get the correct result.
Thanks, so the real and correct values for the S110 are:...

Note that overexposure protection has some effect before the threshhold.
