Unforunatly the e41 error stays as soon as usb remote is not longer enabled and the camera is connect to a pc while running CHDK it I get after a e41 error on my camera. I think it has something to do with ptp. I hope this one also can be solved with a little help, any suggestions?
I don't know anything about CHDK ptp but you maybe could try building without it ?  Insert the following line at the bottom of your platform_camera.h file :

Code: [Select]
#undef CAM_CHDK_PTP   
and see what happens ?

I tried it. It seems not to have any effect, still the same error.

@danistuta

great thing! how do I use them? In Camera Raw, there are no Profiles displayed with those *.DNG Raw Files (4th Tab). Just chromatic aberration etc, nothing else.

Hm, doesn't Photoshop use the badpix info inside the raw files? selected RAWconv

(ISO 3200)

CHDK removes the bad pixels from the raw data in the DNG file (using the badpixel.bin file). It doesn't save the badpixel location info in the DNG file.

On the cameras with BSI-CMOS sensor there are a lot more bad pixels at ISO 3200 than at lower ISO settings.

If you plan to use ISO 3200 a lot then you should re-create the badpixel.bin file with the camera set to ISO 3200.

You have to go in lens correction of camera raw and active "enable lens profile corrections". Then you can choose profiles I've done it in the menu.

hey guys, i can't figure out how to enable that focus lock, i am pressing half shutter until it focuses then Left (the button with the flower on it right?) and nothing happens.. both with ALT mode on and off, am i missing something?

by the way thanks a lot for this CHDK! i'm trying to test everything right now, so far no problems, except that i can't plug in the usb cable and get the photos with CHDK turned on, so i have to first turn it off to work.


EDIT: oh looks like AFL didn't work because i had Servo AF turned On, turned it Off and now i have the focus locked in video mode, so much better!

do you guys think there is any way to make the camera record 60fps at 720p? it can record 120fps at 480p although the quality is really low..

Perhaps this is why?

Using Adobe’s Lens Profile Corrections
You can access Adobe’s Lens Corrections in three locations—Adobe Camera Raw, Lightroom 3 or Photoshop CS5’s Lens Corrections filter. Lens profile corrections were first introduced in Lightroom 3. To get lens profile corrections in Adobe Camera Raw CS5, you need to download a version that has been updated after the release of Lightroom 3. You can download the latest free update at www.adobe.com/products/photoshop/cameraraw.html.

1.01G firmware dump: http://www.box.com/s/cx1bjvtfmzga7ftmygac
and port: https://github.com/stefantalpalaru/CHDK-ixus220_elph300hs-101g
compiled (including PS.FI2 for manual loading): http://www.box.com/s/qh1ots6bxvjogvzyaqal

I don't have access to the hardware, but the camera owner reports running CHDK successfully and the only problem so far is a camera freeze while switching to the "Movie Digest" mode.
