Heres the link for the sx10is 1.03c dump
http://www.zshare.net/download/6285529847919831/
Are you sure about 1.03C as reported fw version ?

Your dump is an 1.03A dump:

  00068830   00068830      0   Apr 16 2009
  0006883C   0006883C      0   09:16:03
  00068848   00068848      0   Firmware Version 1.03
  00068868   00068868      0   Firmware Ver GM1.03A


and is identical with an 1.03A dump (except from the params/user data at the dump's end).

Now vers.req reports 1.03A, but when the camera first came out of the box it reported 1.03C and I triple checked it at the time.

Hi
I find the problem with sx10 and external flash from Nissin.
When external flash is connected then shutter time is always 1/250s or longer, i tried to override shutter time but it doesnt work.
With builtin flash is ok and shorter times works.
Any idea whats im doing wrong?

Great job on the port!  1.03c is working beatifully on my camera.

It took me a while to figure out how to install, here's a quick description.  If you don't care about auto booting, you can skip the AUTOBOOT steps.

1. AUTOBOOT: Format your card to be a maximum of 4G FAT16.  (I used gparted on Linux)
2. Unzip the full download into the root dir of your sd card.  I ended up with 5 files and 1 dir in the root.
3. Unmount the sd card, then eject it.  Always unmount first.
4. Push the play button to turn on the camera in playback mode
5. Hit menu, scroll to the bottom, hit update firmware.
6. Now you're in CHDK!  Go nuts.

7. AUTOBOOT: push on the print button in the upper left until you see <ALT> in the lower right of the display.  It takes a few tries.
8. AUTOBOOT: Hit menu.  Select miscellaneous stuff -> make card bootable.  Nothing appears to happen.
9. AUTOBOOT: Turn off the camera, eject and lock the SD card.
10. AUTOBOOT: now you'll boot into CHDK whenever this SD card is installed.  Too cool!

OK, now to try to figure 1/10th of this new capability out...!

Hello, last night I tried 512 sec shot with help of CHDK. See what I got -




How you see in the left upper corner is something pink, what could it be? When I googled for it, I found this shot - Night Sky 3 also made with SX10IS + CHDK, so it means that it could be a "bug" from factory in all cameras?


And there is one more strange thing - If you look in my pic to the tree, you can see that the stars are visible through it... how that can be possible? :D Maybe these white dots aren't stars, but artifacts from ISO which was set to 80?

Hej,
Those are hot pixels, you get more of them with the sensor heating. Would be great to see the SX1 in this situation, by the way, it should beat CCD sensors big time there.

I understood it is caused by heating of the LCD after long use. Check the thread about long exposures: http://chdk.setepontos.com/index.php/topic,94.0.html

These are indeed artifacts, I don't know what caused them. The real stars are the horizontal strips in your picture. Your exposure time is so long that the stars move a significant distance.

Why? There is no reason a CMOS sensor will be better than a CCD sensor (when they are the same size). In fact, image quality of the SX1 is usually a bit below that of the SX10.

The pink left corner could be due not only to sensor heating, but also to some radiolectronic interferences from some electronic device of the camera. Some DSLRs from Nikon (D70, D80...) were quite prone to this. Nothing to worry about (other than the extra work in pp to hide it...).

Try also to reveal this kind of shots using Adobe Camera Raw and Photoshop. ACR has some special skills to deal with the hot pixels/noise, perhaps some "artificial" reduction, but it works.

BTW, I had same results in long exposures with my SX10, so it doesn't have to do with your cam :)

Saludos!

Hej,
CMOS heats less than CCD.
