New build (15)

Hi, my friends! :)
I published new build: http://malbe.nm.ru/chdk/
Review of new functionality and fixes:
NEW EWAVR feauteres :
+ raw files merging
+ raw files development (averaging of several raw files via file system)
+ Added free/total space message in file browser
+ Added bad pixels patch (experimental) (via file- pattern)
EWAVR Clarification:
This feature is turns on if text file with name "badpixel"  exists in the CHDK directory
Line structure of trhis file:
x1,y1
x2,y2
and so on
Here {xn,yn} are the coordinates of bad pixels in RAW file format
To recieve this coordinates you should to capture shoot with a cap on the objective. After that you can use this program:
http://ewavr.nm.ru/chdk/show_bad.zip
and from myself:
+ Added new menu key for EWAVR option "Show OSD in review mode"
+ Barney Fife English grammar corrections in menu items names
+ Fixed: errors in basic commands "Set_av96_direct" and "get_far_limit"
+ Fixed: false visualisation of overridden shutter speed values that greater than 0.32767 or Subject distance values that greater than 32.767
+ Fixed: Now Tv-bracketing should properly work on ixus800-sd700
+ The Algorithm of Subject Distance Override was changed. Now every shift of subject distance override value changes its quantity by adding or subtracting of factor value. For example if value factor of 100 is set and subject distance override value is equal to 89 than pressing of key "KEY_RIGHT" results in changing of subject distance override value to 189. It can be expressed via next equation: NewSD=OldSD+(-)factor. Besides in alt mode with manual focus mode extra visualization was added. Now value factor is showed on the display. Additionally when subject distance is changed via alt mode feature focus is set in real time
+ Now real apertures values is showed in the menu "Override Aperture Value"
Thanks

it's great. at the long end of the zoom the 14.25 aperture override actually works... OMG
I just took a set of pictures of a 100 W lightbulb's filament and it is a long way from being overexposed... you can actually see the differences in brightness in various areas of it. this is awesome.

Hi AllBest,

Again, congrats on a great build! Tv Bracketing indeed works on my SD700!

I also tried the other features, you & EWAVR sure push this forward!

My solution to the Tv bracketing issue was different, you might consider it:

It turns out the M-Mode in the SD700 is just marketing-speak for a P-Mode, so I went to:

platform/ixus800_sd700/main.c

And modified: "    { MODE_M,                  32772 },"
To become: "    { MODE_P,                  32772 },"

It solved the the Tv bracketing issue, but removed Av setting (?). Actually, for SD cameras, it seems an ND-Filter setting is more appropriate, since the Av is tied to the zoom. See http://chdk.wikia.com/wiki/SD700_CHDK_Porting for a small discussion.

Thanks,
mkmenuts

This item was removed only for SD and a560 cameras. Did you test aperture override on sd700? Successfully?

Yes, playing around with the Av setting turned the ND-filter into a manual setting, very convenient in bracketing as well.
Since this is not really Av manual mode, but merely going between the two sets of Av values possible, I think it needs a special menu setting. You were right to remove the Manual Av from SD cameras.

BTW: How did you find my code suggestion, does it make sense?

in Allbest version v15 if I join or average 2 RAW photos -camera make file result with last name RAW and extension *.WAV
example:
img_5039.raw and img_5040.raw make img_5040.wav

why not img_5041.crw or similar with extension *.crw?

maybe you are right
but why *.wav?
not *.crw1 or *.raw

if I upload files to my PC photo with extension *.wav my pc been try open with Winamp ;) and I must rename extensions manually

if output files been have another (not *.wav) extension be OK
don`t you think?

I engaged this on an S3, but it makes no difference. Except for that battery icon that remains no matter what, I have to turn off OSD manually to make it disappear in Review mode. (It's always been this way ever since the beginning of CHDK.)
Barn, I think that you are not quite right. It's new feature. Here we talk about review mode immediately after the shoot. Please see you menu http://www.steves-digicams.com/2006_reviews/s3is_pg4.html (Review - Post-capture review time, Off, Hold or settable for 2 - 10 seconds )

I like the way this is *supposed* to work, but there's still some bugs in it on the S3. When changing the "Factor" value to 1000, then it prints more than one line of "Factor" on the screen. And the SD Override doesn't actually work now. It changes the numbers but the selected focus distance isn't applied to the lens.
Barn, are you shure? It works fine on my a620. Now camera sets focus twice - at time of changing of  focus distance in alt mode (you can observe subject distance and others quantities in misc. values. Here you can see the process in dynamics)  and at the time of the shoot. New feature is only first of them. Second one works as early....
