focus stacking only working in Movie Mode? 550D

[sawomedia]

I dont know if this is the intended behaviour:

Stack Focus does not work in Picture mode (Manual) on my 550D

It causes the overlay menu to show a checkerboard background and the
functions are all messed up - i have to reboot the camera.

In Movie Mode it is working fine.

Thanks

It only works in LiveView mode. In "normal" mode it only takes one
picture.

Checkerboard? How did you get that?

[sawomedia]

Oh ok, thanks - i somehow didn't think of this.

It somehow works now in Live View Mode - with a slight bug:

I can see the Focus change and stay for the exposure time, but it
doesnt save any images.

Anything i am missing?

With the checkerboard, its strange. I tried to do a screenshot, but it
shows the menu as it should be (solid grey)

I have made two pictures of the menu that happen after using focus
stacking in manual mode without LV on.

In menu:

When closing the menu:

During taking the shots of the display, i recognized that when the
display is shut off (via the display sensor)
and comes back on, the menu is again as it should be.

Thanks :)

I've never get those checkerboards; seems like memory corruption.

Can you do a small video showing what buttons you press?

Also, I didn't have any save problems. On the other hand, when I've
tested this, it was usually the first thing I did right after starting
the camera.

Yes, i recorded a little video here:

http://www.sawomedia.de/share/img/ml/focus_stacking_bug.mp4

the first step is the checkerboard bug and the display-sensor "fix"

then i reboot the camera, go into liveview and take a stack focus.

note the strange behaviour after the stack has run through.

i press the "play" button and the cam seems to hang, then takes a
picture or two
of the last focus state.

when i finally come into playmode, i end up having 4 images of the
same focuc, but no stack.

This build **does not read** config file. I believe there's a memory
corruption there.

Can you test if this fixes focus stack, play issue (221) and clear
view HDMI issue (228)?

Please tell me if you have any stability problems with this build.

I just tested the play issue (221), that I also experienced with the
previous build, and it is now fixed. :-)

The new built seems to be stable so far.

Hi, Alex, I was working on another bracketing task and I had a lot of problems with the filesystem (with the first version of 550D port: since 12 November I don't get time to work on it  :-( )
 
The program uses a logfile and we create the file only if the file doesn't exists. Something similar to that.


logfile = FIO_Open( "logfile", O_RDWR );
   if ( logfile == INVALID_PTR)
      logfile = FIO_CreateFile( "logfile" );

I don't know if this can help you.

The new problem thah arises is that FIO_Open writes from the beginning of the file ...

And also I remember we need delete magic.cfg from the filesystem, because that makes a system prone to instabilities, I mean I think the stability problem related to config file
were here since first versions of ML port.


Thanks:

Fernando
