Re: gPhoto2 - Regarding Capture-Tethered

Hi Marcus.

One more ques please:

In my Canon 6D, I wanted to detect if any specific Camera Settings
changed by On-Camera by Button-LCD. I am checking  "--wait-event" Log's PTP
property which should have a unique value for each Camera Settings?

*Changed Shutter Speed:*
UNKNOWN PTP Property d1c3 changed
UNKNOWN Button 32789
UNKNOWN OLCInfo event mask=1
UNKNOWN OLCInfo event 0x1000 content 00
UNKNOWN OLCInfo event mask=1000
UNKNOWN OLCInfo event 0x1000 content 01
UNKNOWN OLCInfo event mask=1000
UNKNOWN PTP Property d1d9 changed
UNKNOWN PTP Property d1d5 changed

*Changed F-Stop:*
UNKNOWN PTP Property d1c3 changed
UNKNOWN Button 32789
UNKNOWN OLCInfo event mask=1
UNKNOWN PTP Property d1d9 changed
UNKNOWN PTP Property d1d5 changed

*Changed ISO:*
UNKNOWN OLCInfo event 0x1000 content 00
UNKNOWN OLCInfo event mask=1000
UNKNOWN OLCInfo event 0x1000 content 03
UNKNOWN OLCInfo event mask=1000
UNKNOWN PTP Property d1d9 changed
UNKNOWN PTP Property d1d5 changed

From the above data I don't see any specific unique value which I can
consider against a specific Settings i.e. Shutter, F-Stop or ISO.

But in Nikon D5100, I can easily detect it by:

*Shutter:* PTP Property 500d changed
*F-Sop:* PTP Property 5007 changed
*ISO:* PTP Property 500f changed

Can you advise how to get the unique PTP  Property of Canon Camera Settings?

Thanks in advance.

Reagrds.
