EWAVR,
Can you please find a way to keep the iso fixed in video mode?

We can change everything (ISO, exposure time, aperture) in video mode, but only if exposure is locked.

Hi all

I discovered CHDK time ago and bought a Powershot A640 knowing about its RAW capabilities, thinking of it as a pocket advanced camera (in fact not so pocket).

I was expecting CHDK for the SX10 because I like it a lot, and I'm happy to see that it exists now. But given that it's only available for ver. 1.01a at the moment, I would like to know if there is some reason to think that it won't be available for 1.00c and 1.01b.

Don't have any problem in buying one and, if one of those two versions, helping (testing more than assembling... :( ) in the developement of CHDK. Otherwise I'd look for a 1.01a version, shop by shop.

Thanks in advance, and thanks for all this work!

I have a couple of pretty basic questions, after playing CHDK on the sx10 for a couple of days.  First off, thank you to the developers/porters!!!

1) When shooting in RAW mode, files are about 15mb.  I can still set my jpeg to whatever size I choose.  Question: if I set my jpegs to ~2mb (M3), will I get a RAW file with less detail than if I set my jpegs to 10mb (L)?  Previously, I was shooting jpegs in 10mb and then cropping.  So, if I could just shoot at 2mb and deal with the full detail and cropping in RAW for those photos I want to hang on to, I'd be one happy sx10 owner.


2) Anyone know of a shortcut to toggle RAW on/off?  Alt+Func or Alt+ +/- doesn't seem to be working for me.

3) Is motion detection on this version?

4) Anyone know where I can buy a USB cable remote or USB wireless remote to work with the sx10?

5) Has anyone been able to get the RAW Develop option working?  I wanted to see if I could convert the RAW in-camera, as I heard that can reduce noise more effectively than how Canon treats noise at high ISO when automatically creating a jpg.

Only significant difference between sx10 and sx1 is, perhaps, speed in shooting raw and video 1080p.  The RAW and remote were my big needs.  Also love having a battery meter.

Wishlist: I have an eye-fi wife card.  I'd love a jpeg wrapper for RAW so it automatically off-loads those shots from my SD card. 

Again, thanks.

@Rory
Hello & welcome...

1) CHDK RAW is always a full sensor data dump, the JPEG size/settings doesn't matter
2) DELETE key in <Alt> mode
3) http://chdk.setepontos.com/index.php/topic,471.msg21328.html#msg21328
4) try searching the forum...
5)
SX10 1.01A updated: added wheel support, multipartition support, RAW sum/average for 12-bit RAW (to do: curves and RAW subtract  for 12-bit RAW)

...all these informations are already here in the forum, most in this thread ;) - give the search function a try...
BTW - this is the SX10 porting thread...

fe50.  Thank you kindly for the answers.  Didn't mean to hijack the thread.  I'm just learning my way around CHDK and this forum.  Thanks.

Alright, sdminste.exe is doing fine. But the only "problem" is that every time I wan't access to the RAW photos, I have to swap the partitions. The other work-around is probably installing that custom driver, but I think I"ll make do with this swapping method for now. Thanks, fe50! :)

EWAVR,

We can change everything (ISO, exposure time, aperture) in video mode, but only if exposure is locked.

Hi! Thanks for the heads-up. But I wan't to manually change the ISO which normally is AUTO. Measuring the exposure and locking it in a suitable position does reduce the iso, but it's all up to the camera to decide what iso to use. The only setting available is the exposure bias. I wan't to manually specify the ISO before starting recording (to 80 or below), and the apperture too, if possible. I'm new to the chdk, so I don't know exactly how to get the things done, if already possible.

One last question:
Is it possible to increase the continuous shooting speed of the JPEGs (only jpg, no RAW), at least with lower resolutions? TIA :)

Unfortunately, I don't know how to limit ISO and leave autoexposure working in video.

Rewind this thread, fe50 wrote about ISO3200 mode and 4 fps @ 2MP. IMO, minimum ISO in this mode is approximately 300; -2/3 Ev correction is also useful.

Hi all.  I've been waiting since I got my SX10 around Nov/Dec '08 for CHDK to be ported... and I'm happy to see that much progress has been made.  Now the time has come to ask what I need to do to start using it.  I'm using Firmware 1.01A, and I see that firmware has been ported.
When I've looked a little at CHDK build descriptions in the fairly recent past, I've seen multiple builds that specialize in different things, but no build (unless I'm looking in the wrong places) that does everything CHDK is capable of.  I would like to put one such build on my camera.
Also, somewhere I read that you had to use a 4GB or less capacity card.  Is that for the firmware dump, or for actually running CHDK?  I routinely use 8 and 16 GB cards due to the amount of video and photos I take, and would like to use it with those.  Also do I have to put CHDK on each card I use?  I currently swap between 3 8GB cards and 1 16GB card.

Or should I make a new thread to ask this, or is posting at 2:55am PDT not the time when ppl are on here reading the board?
