When you shoot manually, are you waiting for the camera to focus with the shutter at half press, then pressing fully? Or just pressing the button right away? Quick press sometimes has problems, but this port already has the usual workaround.
Quick pressing takes a normal shot ignoring the overrides. Long pressing and letting focus takes the minute exposure. I haven't tried it with other shorter values yet but I can if you want me to.
Lol, I never claimed to be a photographer that knows what they're doing! I use CHDK mostly for astrophotography so I have it in either continuous or with a basic loop script. Thank you for the help!
press "shoot_half"while get_shooting <> 1 sleep 10wendclick "shoot_full"
I've attached a test build with a variation of the quick press workaround. Please let me know if it solves the problem.
FWIW, a script I wrote for astrophotography is available at https://chdk.wikia.com/wiki/Lua/Scripts:_Fixed_Exposure_Intervalometer
Sorry just got around to trying this. Put this in place, changed only the same settings as above, and quick pressed several times and that seemed to do the trick. The TV overrides are working in this build with the quick press.
Also, if you can check whether ISO overrides work, that would be helpful. To test, you can set ISO to 100 in the Canon UI, camera in P mode. Override ISO to 400 in CHDK UI, no other CHDK overrides. The resulting shot should be overexposed.
I couldn't see a difference between 100 vs 400 but setting the canon to 80 and the ISO override to 1600 made it obvious.
