OK, new firmware works on A4000 with 101a. Pictures in DGN format  is darker, this is OK. I feel not now pink shade, but perspektive by jpeg and by dng is not equivalent. By DNG has picture more curve/bending. It is viewable by photo taking of edges of table. Maybe this is feature of lens, and Canon has postprocesing for correction by jpegs (but this "fish-eye" effect is natural nice !)

I found that I could use the gimp Filters>Distorts>Lens_Distortions filter to correct the warping just by tweaking the "main" parameter.  I wrote some scripts for doing this via batch processing.  If you're interested, I could probably zip my stuff up and attach it here.

The DNG image is exactly what the sensor captures - no processing of any type applied.

Could someone send me a link to the pre alpha version for 101a?
101a version was tested by atirage21, I submitted patch to add that version to autobuild, it should be available soon..  Please test it and report bugs to this thread.

@rkomar,
latest changes to 101b will be available at autobuild server too.

I attached a zip file containing the scripts I use for batch processing my DNG files.  The shell script for combining all the operations is for Linux systems.  It may work on a Mac if all the necessary packages are there.  The script won't work in Windows, but the ufraw patches and the gimp scripts are probably still useful to some on that platform.

Hi everyone!
I am using the last version of chdk for my A4000 but I am having some problems when making photos with a script that takes one photo every 7 seconds.
Some of them are corrupted (part of the photo is grey)
The bad ones are the ones larger in size (above 6200 Kb aprox)
I save them in jpg, no overrides in chdk, resolution L.
Anyone with this problem or can try the script in his camera? (see attachment)
Thanks

What happens if you increase the time between pictures to 20 seconds ?

Do you accidentally have RAW enabled  (that can happen without you knowing it via CHDK half-shoot shortcuts)?  If so,  it will greatly increase the time to save files.

One things you could try is to replace the shoot() call with this :

Code: [Select]
function manual_shoot()
  press("shoot_half")
  repeat
    sleep(10)
  until get_shooting() == true
  press("shoot_full")
  sleep(100)
  release("shoot_full")
  sleep(100)
  release("shoot_half")
  repeat
    sleep(10)
  until get_shooting() ~= true
end

It happens the same.

No, just jpg.

One things you could try is to replace the shoot() call with this :

I don't know where do I have to insert that code in the script.
Sorry, I have no idea.

Thanks.

Copy waterwingz's code to your script, then replace call to shoot() (line 61) by manual_shoot()

Modified script attached.  I haven't had a chance to test it yet - will try that later if I don't hear back from you.
