--Current_tv gets throught the smoothing mechanism--feed_smoother(current_tv)--smoothed_tv=smoothed_value()smoothed_tv=current_tv
The problem is that when it's getting dark or bright, exposure does awkward jumps. I plotted some curves and it looks like the script doesn't ramp up ISO smoothly when Tv is already cranked up to max,
possibly because of noise in bv measurement (I think I'm hitting the noise floor of the CCD before the script is running at max ISO + max tv and that my camera is noisier than yours).
And how does exposure stay smooth when Sv is the only thing that can be altered (when Tv is at maximum)?
when you see jumps in ISO, do you also see the same jumps in current_tv?
Unless you have drastically changed the dusk start and dusk duration parameters.....What does dusk_factor say when you have those jumps?
You could post the PR_SCREEN.TXT file, so I could give a look
? I don't understand ...shoot_tv is smooth (or should be) but if the shutter time correspinding to this tv is too lng then we shorten shutter time and compensate with a higher ISO.
current exposure is 50:loopcamera shoots at 50camera examines frame, says "it's too dark!" and decides to expose morecurrent_exposure is increased by 100 and goes to 150camera shoots at 150camera examines frame, says "it's too bright!" and decides to expose lesscurrent_exposure is decreased by 100 and goes to 50goto loop
