This adds ND filter control for cameras that have both and adjustable aperture and ND filter.
If I remember correctly, it wasn’t possible to change the ND Filter while you are in ‘quick’ or ‘continuous’ running mode. Would this work on my G1x now?
I have some presets for rawopint. If I use them on EOS M3, I got sometimes the errorerror("meter step too small")Yes I know, that has to do with the larger senor size.
Just for understand how ND works on my cams with IRIS and ND filter (G1x and S110)1) SunsetIn this case, I want that ND goes in after start - I expect that TV goes to longest exposure time. - Than ND goes out. - Tv goes shorter - Tv goes again to longest exposure time. - Than ISO will increase Script settings:ui_nd_force_e= 1 => ND in
ui_nd_value = 284 => (G1x) because auto detected does not workui_tv_nd_thresh_s10k = ui_tv_max_s1k*10If this is correct?
Why (ui_tv_max_s1k = Sec/1000) and (ui_tv_nd_thresh_s10k= Sec/10000) are different?
You might need to make the ND thesh at least slightly less then the tv max.
First run with ND on G1x. Looks like Tv goes to 2s and then ISO increases to 1000 (at 186). Than ISO goes to 160. Different as I expected but from motion blur it is better to keep the 2s.But why ISO goes from 1000 to 160 and not from 800 to 100? Is this the Hysteresis?

how did your run use the ND at all?
and it looks like it did the right thing, although I didn't really design it for this.
To avoid this, you could make ND thresh 1 second, hysteresis 1 stop, and then the ND should be removed at 2 seconds,
Quotehow did your run use the ND at all?Before I start the script, I set ND in the Canon UI.
Sometimes (when I’m traveling) I’m using the ‘HOSTLUA’ environment. Unfortunately the 'rawoplib' will not be supported. I tried to implement these functions with simply returns but haven’t finished yet.
Would theSimulation mode run in this environment ?(ui_sim=true "Run simulation")
Sorry, that was a poorly worded rhetorical question. What I meant (and explained in the following text) was: Given that the Tv (+ hysteresis value) where the ND was supposed to be put out was longer than the maximum, why did the ND go out at all?
That would be a lot to implement...
