I tried to apply the Lens Profile from http://chdk.setepontos.com/index.php?topic=6241.msg74486#msg74486 in Lightroom, but that gives me real strange results: the whole photo is completely warped. For example, the Scott Monument (Edinburgh) is completely deformed, not even standing upright anymore. How are results with you guys?

Hi, my first post...
Just a question from your experience: I did not managed to have faster shutter
speeds than 1/3200 or slower than 15 secs (the range that the sx220 has already).
I'm I doing something wrong or what I have to pay attention?
PShot SX220HS 101C, running sx220hs-101b-0.9.9-1491-full_BETA.
Thanks for patience.

Hello & welcome !

Just a question from your experience: I did not managed to have faster shutter
speeds than 1/3200 or slower than 15 secs (the range that the sx220 has already).
Set your overrides (e.g. faster/slower Tv) in the CHDK Menu --> Extra_Photo_Operations.
Note: The Canon OSD doesn't show values outside the range the original firmware knows, the same applies to the EXIF meta data...

Many thanks fe50
so I 'm trying to set a value in EV mode and then how can I check the actual shutter speed? Is there any EXIF reader that can read correctly?

Most cameras contain additional meta data including the "real" shutter speed in the EXIF makernotes section.
Phil Harvey's great EXIFTOOL let you view & edit all EXIF data...

Apart from that you may check brightnes etc., for fast shutter speed read also this wikia article...

after 2 hours testing, using CHDK with my SX220HS, I can have the same shutter speeds as the camera operates (the fastest shutter s 1/3228 checked with 3 Exif readers).
Maybe the problem is that I use CHDK for firmware 101B & the camera has 101C? Seems stupid...
In general this version seems to work with this SX220. Thanks.
PS Xmas ...coming!

I can't enter <alt> mode with DISP+Func Set.  I get the splash screeen when powering on. Rinning sx220hs-101b-1.0.0-1571_BETA. Any suggestions?

Press & hold DISP, then press FUNC Set immediately...

Thanks. I was doing exactly that, but for some reason it was not working. Finally after 20+ attempts it worked. I've seen the same happening with my SD4000. Interesting.

On another note, I have a script that works OK with SX200 but not with SX220. It has a section to recognize if the camera is in continuous mode. It calls function get_drive_mode and checks if it returns 1. Was that changed, and what is the code for the 'drive' mode now?

Thanks.

get_drive_mode on this camera returns 3 only if the camera is in custom timer mode.

To detect if the camera is in countinuous drive mode you can manually get the prop value with "get_prop 102". This will return 1 for continuous and 2 for continuous AF.
