Here's the test ND test script I wrote, along with some results.
On both elph130 and d10, I noticed that the zoom level seems to change very slightly with/without ND.
I made dumps for SX50 and SX230 with your method:SX230Prop 18 could be filters stateProp 103 could be filter value (325)SX50Prop 297 could be filters state
Really the zoom? May be Canon made just a different crop to reduce vignettation in the corner with ND filter…
It really looks like the ND information isn't in a propcase for these cameras
Another test with SX50. Dump until 1000. No differences over prop 273. Prop 297 didn’t change again. Test was made in TV mode. I can really here the noise, when ND goes in and out…
I can probably provide a script to do this later if it's not clear.
You can also use the chdkptp devutil dlog* commands.
I have chdkptp installed and I can connect the SX50. The only think what I made in chdkptp before was ‘shoot’ in ‘Live’ .‘devutil dlog*’ didn’t say me anything…
recdlstart... press shoot half in a scene that doesn't trigger the ND in canon firmware, release ...dlgetcam no-nd.log... press shoot half in a scene that does trigger the ND in canon firmware, release ...dlgetcam nd.log
To get camera log, try the following
> recERROR: already in rec> dlstartlog started: A/dbg.log> dlgetcam no-nd.logA/dbg.log->no-nd.log> dlgetcam nd.logA/dbg.log->nd.log
To be sure, if the noise which I hear comes from ND, can I set the cam to MF?
Another try wit SX50TV Mode. TV=1/15s. ISO100. MFIn the shadow => Aperture goes to f3.5 (red) the might be darkIn the sun => Aperture goes to f8.0 (red) overexposed and I heard switching of ND
I’m wondering why the size of no-nd2.log is less than half size of no-nd.log…
