One more question JTL. Like I mentioned above, while I was playing around with it, I didn't realize I was at iso50. Once I realized, I changed it. How do I go back to iso50? :confused: I can't find the answer in the CHDK FAQ page :mad:O.K...
Follow these script creation instructions from Chem:
This is it:
rem Sets ISO value directly
rem Use at your own risk!
@title Set ISO - DANGEROUS!
@param a ISO value
@default a 100
set_iso_dangerous a
end
Copy this into notepad and save it in the script folder on your SD card as custom iso.bas (or some other name, don't use caps) make sure notepad won't save it as custom iso.bas.txt. Run it as any other script, by clicking the shutter button while in <ALT> mode. This sets the iso, then disable <ALT> mode again and shoot.
The default value is 100 here, but you can put any number you want there. You can change the value in the hack menu but that goes with steps of 1 so I have three custom iso files on my SD card with default values of 25, 600 and 800.
Again, use with caution. I tried iso 10 to 1600 on my S2 and I never had problems with it, but I can imagine that setting it too high could damage the sensor. Very low iso values result in highlight clipping which is unfixable with photo editing software.But, he left one very important little thing out of the instructions. After you've created the script and pressed the Shortcut Key to enter ALT Mode, you must press the SET Button to bring up the Script Menu. Choose the new ISO script, then press the Shutter Button to run the script. When in ALT Mode, just press the SET Button and you can use the arrow keys to change the ISO setting. Once you've run a script, it becomes the default script until you choose and run a different script...so unless you're setting custom ISOs or choosing a new script, you don't have to use the SET Button again....only the Shortcut (ALT) and Shutter Button to run the currently defaulted script.
The script does not run at start up, so you have to remember to enter ALT Mode and press the Shutter Button to run the script each time you start up. It will default to your last ISO choice. Let me know what happens....
Also, when saving the script file in Notepad, choose Save As, type in iso.bas as the name (or any FAT 16 compliant name) and use the dropdown on the Save As Type line and choose All Files. Leave the coding as ANSI. Chem's instructions were not specific enough...a pet peeve of mine!!! :D But, of course, big thanks to Chem for posting the script!!! We owe him our gratitude!!! :):):)
FYI, I tried ISO 25, but got a severe WB shift...let me know if that happens on your camera as well.
