Am I missing it or is there no Aperture override in the ported version as of yet?
All Ixus models & some cams of the A-series do not have a real aperture (iris), they have a ND filter instead...

What is the ND filter? How does it wors? I look in the Allbest manual and in the forum but I cannot find anny information. Could someone post a link to unterstand how its working?

Thanks

this one says version 1.0.1.0 will it work?

Er, are you sure you don't mean 1.01a? chr's current port supports both 1.00c as well as 1.01a. Just install the relevant version.

Do a forum search, there's a few posts around about it. Basically what the ND filter is supposed to do on the IXUSes is emulate f/8.

Basically, many small form factor cameras such as the IXUS 80IS/SD1100 only have one real aperture setting, and that is f/2.8 when not zoomed in.

When your camera detects a really bright scene, it'll swing the ND filter in. This in effect makes the scene look darker and will effect the exposure (but not depth of field like a real aperture would).

With the ND filter in, the camera can select a slower shutter speed without over-exposing the entire scene.

With CHDK, you can keep the ND filter out, and just select a faster shutter speed to compensate.
In CHDK, you can perform this operation by going to:

Extra Photo Operations -> ND filter state

Just select one of the options from there:
Off/In/Out

- 'Off' means the camera is in control of the ND filter state.
- 'In' means the ND filter is swung in.
- 'Out' means the ND filter is not in.

For photos of an ND filter working in a disassembled IXUS, have a look here: IXUS800(SD700) inside the lens images. There is a ND filter!

i've been playing around with the RAW and HDR with this--it doesn't look like dng4ps2 doesn't support our camera yet (and also doesn't have a color profile either). i've tried out picassa and xnview (both can accept .crw) but can't find a RAW+HDR solution yet..Qtpfsgui doesn't like the .crw's created.

CHDK raw's are not in canons CRW format. Try dcraw.. (or ufraw, is a frontend for dcraw)

qtpfsgui uses dcraw's sourcecode internally to import RAW files.. Maybe you need a newer version of Qtpfsgui.

Then you're doing it wrong. You need to create a file called vers.req on the SD card to get the information needed.

Well guess what, I finally was able to take my first HDR images!  I think the write up for a PC instructions may need a little revamping (or I just read too quickly).  Anyway, CHDK is working for my camera now.

Thanks!

things i found out over the day re: raw and hdrs..

it looks like while Qtpfsgui can import .crw's directly (and dng4ps2 support sd1100 too, complete w/ the right colors), but u can't use hugin's align image stack function (and neither with .dng's made by dng4ps2) with the stable ver of Qtpfsgui. the beta ver accepts it, but keeps crashing on my windows when i try to apply the align image function. i think it's something on Qtp's side to fixup.

Hi..

Just a simple question(s) about installation..
- when you say 'Lock the card and power on', won't card locking cause the camera to refuse saving any pics to the card?
- do i have to do the installation once? or will this happen every time i power on the camera?

thanks alot for the great work.
