    You mean by Constant Exposure Mode, the Long Shutter Mode?


    No, the option in Bracketing\Overrides menu.

    Okay, it helped a little. Really wish there was a way to set the aperture though

    Do you mean you wish there was a way to set the aperture in the sense as in make open it to the full, or to reduce it?

    Its impossible for any aperture, or anything for that matter, to open up more than it physically can. By default it is open to max no matter what you do on IXUS 105.

    So I'm guessing you want to reduce the aperture. You can simulate the effect with ND filter.

    Do a little experiment. Set your camera Tv (shutter speed) to 1/6, and then, if you have a ceiling fan (kind of like what I posted a photo of a few posts back), turn the fan on full, and take a photo. It will have motion blur right?

    Now, turn the flash on, let the Tv remain at 1/6, set the ISO to lowest i.e 80 which is bound to create even more motion blur, and take a photo. You would be surprised that the photo will be crisp.

    In above example, without a flash you would need a real big aperture to be able to crank Tv upto 1/1000 in low light conditions to be able to freeze a fan, however if you dont have a big aperture, you can get relatively good results with a flash.

    The point I was trying to make was, not having an aperture is not really a disadvantage, it can be fairly controlled using other methods. Even DOF, which is mostly thought to be an issue with this camera can be simulated using focus stacking (http://en.wikipedia.org/wiki/Focus_stacking)

    Hi everyone!

    I'm an absolute beginner with CHDK. I've bought my Sd1300 for about a year and has always wanted to increase its flexibilities. Can anyone tell me what has been working and what has not? How do I install it and if there's any risk of doing so? Thank you!

    (You can find some test versions on the porting thread below)

    Where can I find and download a test version of CHDK for Canon IXUS 105 (Firmware Ver GM1.00D (1.0.0.0))?

    Only SDM as a variant (i.e. is not present simply CHDK without SDM)?

    P.S. The SDM contains not all functions which I know in CHDK. Though probably the IXUS 105 have a little functionality.

    I have read through quite a bit of this thread, but I'm scratching my head a little..
    I just got a SC1300 IS for Christmas and I am wanting the ability to shoot in RAW since I will be using this camera primarily for underwater photography. I don't want to fork up 6k for a 5dmkII and an ikelike case at the moment and I don't want to invest in a case for my 40d. This will have to hold me over..

    I have already loaded the camera with SDM 1.85 and it seems to work fine in shooting in RAW, but I am having some difficulty opening the CRW file. I have the latest camera RAW installed for Photoshop CS4. I am able to open CR2 files from my 40d just fine. Is there a trick to this?
    Thanks,
    Jake

    Doesn't these builds use SDM RAW routines? In that case, it would look more like this: http://stereo.jpn.org/eng/sdm/dng.htm
    Or at least, I could not figure out any of the solutions listed on the CHDK wiki, so my raw files workflow involves swap_bytes, header concatenation, and importing the EXIF data from the corresponding JPG using exiftool.

    Thanks for your reply. I will have to do some more research on this topic it looks like. Has anyone been able to open a RAW image from this camera?

    SDM was forked from CHDK many years ago.  I am not familiar with the workflows in SDM but would not be surprised to find they are similiar but different.  Perhaps microfunguy (the SDM maintainer) can comment ?

    As this camera was never really ported to CHDK (although I seem to recall working with microfunguy to get basic CHDK functionality working so that he could do the SDM port about a year ago),  you might be better off asking that question in the < SDM forum on Yahoo Groups >.
