Well, for drizzling (or better, other super-resolution techniques) one really just needs a series of slightly-shifted shots -- the shift could be as little as a single pixel, and it doesn't always have to be pixel-perfect. So an ideal setup for that kind of work would be to shoot a central shot, and then shift the sensor some small amount up/down/left/right and take a shot at each subsequent location. There are apps out there that could take the resulting output RAW files and align and process them. I would guess it would be near-impossible to do in-camera.

I'll have to sell some stuff and get an  A720 ;). Thanks. Again, really excited about getting some control over the sensor position...

it is very likely that the genius of Mr. Dataghost will lead to finding the IS control mechanisms on the other IS cams as well. i for one will be patiently waiting :)

What about the orientation sensor on the TX1?


Camera powers-off immediately.

My friend said that he has found a menu item for the A570 for creating two partitions and swapping them.

Does this allow him to use cards bigger than 4GB  ?

Yes, CHDK for A570 supports two partitions boot.
Of course, card can be partitioned by several ways. One of them - http://chdk.setepontos.com/index.php/topic,551.msg4438.html#msg4438.

Thanks.

What prevents this method being used with other 'A' series cameras and the TX1  ?

Nothing prevents, any VxWorks camera can be added (now supported A550, A560, A570, A630, A640, A710, G7, S3IS and even IXUS700). But writing mount.c in assembly for each firmware is exhausting work  ;)
For old cameras without SDHC support multipartition boot is not too useful feature (any SD card can be formatted as FAT16). For IXUS700 this is made due to very low FAT16 performance on this camera at reading directory content (list of 200 files CHDK can read during 1-2 minutes!), FAT32 on this camera is pretty fast.

@DataGhost
Maybe flash-disco can be also included in your branch?  :haha
http://ewavr.nm.ru/chdk/for_test/1.avi - approximately 2 tiny flashes per second (sorry for strobe light effect).
EF.StartInternalPreFlash function used.

Heh, nice. I'll look into it. I'll be away for the weekend, though (boat), so I might not be able to commit it into svn.

does this eventually mean you can disable preflash (in non manual mode)? anyhow, using it for "minidisco" and things like #54 in the "todo list thread" seems to be perfectly possible now. great find. keep up the good work guys.
