okay, will try to follow this for s3is and a620.

So, in both cameras required stuff is absent  :(.

damn. on the other hand, i really never ever used usb to transfer files, so we should also add dng extension for cameras that dont support moving dngs via usb. and for those people who need the function that the associated files are deleted when you delete a jpg - well, we have to take a look at the raw purge feature again.

The setting is a bit out of place in MISC menu, though, I would've expected to find it in RAW menu along with the other DNG options.
We already have a million useful and useless options in RAW menu. Maybe we need DNG submenu in RAW menu.
yes, this is true. i'm sure we will find  a solution :)

Where can be changed the Copyright Exif Tag?
Any photo I take came with a unknow "n" char in this tag.

I look for this tag in the source code but I didn't find it.

Any help will be appreciated. Thanks

I think the version number is wrong. 8.10 is the same as 8.1, so after 8.9 should be 9.0.

No, not really. I'm currently running linux 2.6.26.4 - notice the 26?

(Although i must admit, those chdk version numbers are kinda bogus imho. Everyone is referring to the revision number anyway in case of a bug report or a question .. )

That's understandable if we were going from 8.9 to 8.91, it still works mathematically. But, 8.10 is no different, mathematically, than 8.1. So, I believe we should be at 8.9.

This is the case if we were using fractional numbers for version. But in most software projects the decimal point is not used as mathematical symbol, but to distinguish between major and minor version and in some cases - build number. So we have in fact notation in this form:

m.n

where m is decimal number for major version number and n is decimal number representing minor version number.

If you are using Windows, type ver  in a command prompt and you can see how Microsoft uses three numbers to represent the version - <major>.<minor>.<build>:

Microsoft Windows XP [Version 5.1.2600]

I hope this explains well version notations  :)

a570 100e:

All code very similar to a710. Extension support is the same as for a710:
scan: jpg, crw, avi, wav, mrk, dps, fir
transferable: fir, mrk, jpg, crw, avi, thm, wav

stubs:
DEF(some_f_for_dng, 0x674C)
DEF(second_ext_for_dng, 0x6770)


for ixus70 every version
DEF(some_f_for_dng, 0x7104)
DEF(second_ext_for_dng, 0x7128)

for ixus850
DEF(some_f_for_dng, 0x9A68)
DEF(second_ext_for_dng, 0x9A8C)

edit: test with ixus70 ok

attached diff for ixus70 and ixus850 against r638

Added to trunk in #639 (also a650, a720: 'dng' instead of 'cr2').
Also changed length of empty string in 'imagedescription' and 'copyright' tags to 1.

(for developers: tiff engine now can handle strings with odd length automatically).
