been trying this script on a canon a2400 mounted on my q500 quadcopter. I'm a newbie at chkdsk and I've spent the last week trying to find info on how to make changes in a script. I downloaded a freeware program that allows me to make and save changes to the script but without knowing which lines to changes I guess I'm kinda at a loss. The images I have been getting are at least 2 stops overexposed and from the metadata all the images are shot at 2.8 with shutter speeds generally around 1/1000th with variable iso settings. The images from this camera are terribly grainy so I was hoping to lock the iso at 100 and chance a slower shutter speed. If someone could point me in the right direction I would be most appreciative.

What version of CHDK are you using?  There is a bug in some versions with ISO settings that is unrelated to the script.

The CHDK script parameters for the kap_ uav.lua script let you specify the ISO range that will be used.  No editing of the code is necessary.  It's all right there in the CHDK script menu if you scroll down far enough.

This camera doesn't have CAM_MARKET_ISO_BASE  set, and probably should since it's DryOS R50.

@geebob Please run the isobase.lua script found in CHDK/SCRIPTS/TEST and report what it prints  on the screen.

Don't forget what the H stands for.

The fix for your issue was added to CHDK yesterday.  If you download and reinstall CHDK your issue with 2 stop overexposure will be fixed.   You can keep using the same version of the script.

Waterwingz..just to make sure I'm doing this right. If I go back and run stick utility and tell it to download chkdsk again.. obviously using the chkdsk file it already downloaded would be the same file... the file it downloads tonight would have the fix applied?

Yes.  To be certain, you could manually delete the earlier file first.

Dear waterwingz, where the script write the options of the KAP_UAV? I want to make backup of mine SD cards and I am only copying the kap_uav_3-7a.lua but I would like to backup  the options I select too, do I have to edit the script and set them as Default?

Thank you

p.s. I am waiting you to reveal the fast shutter method, is the pwm one?
