So it looks like the platform_camera.h file for the S100 needs both :
Code: [Select]
#define CAM_HAS_ND_FILTER 1
#define  CAM_HAS_NATIVE_ND_FILTER 1
Tested successfully and patch for 1.3.0 and 1.4.0 has been submitted for inclusion in the autobuild.

Just a reminder, "firm update" booting FI2 support is broken on this cam http://chdk.setepontos.com/index.php?topic=12153.msg119427#msg119427
I just built a ps.fi2 file the normal way for the 1.02a firmware version of this camera.  Works fine - firmware update method loads correctly.

So is this something specific to only a few firmware versions (possible but unlikely)?  Or maybe an issue in the original porting process that nobody ever went back and looked at?


Edit :  Patch file for 1.4.0 attached.  Should we add to autobuild and look for testers?

Can you see if this patch fixes the DNG files when set to 'Full' for the crop size.
Patched and tested all three "sizes".  They all look good now - thanks!
Hi
I tried shooting DNG with my S100 using the HDR option from the top select wheel. This usually seems to shoot three exposures and then combine them, as a JPEG. I tried it with CHDK DNG set to on and it does produce a DNG file- but the results have a purple cast. Shooting single DNG files gives correct looking DNG. I looked at the DNG exceptions list and everything is set to off

It seems very unlikely that this will work, assuming that you were hoping to get an HDR image in DNG format.  And trying to hook into the process such that CHDK can capture a buffer full of Raw image data that has been combined into an HDR image prior to conversion to JPG format would be a lot of work, assuming such a buffer even exists.

Intriguing tho. I also tested hi speed capture with DNG set to on. My S100 struggled to save more than one DNG, but on my Ixus 300 HS it runs like a train, with 8 DNG images saved. Does that seem like a difference in the way buffers are working?

Looking at this,  it seems we might be close to being able to play with "in camera"  HDR algorithms now.  (scripting or embedded C)
As a CHDK user, not a coder, this kind of thing is useful coded not scripted.
Do you think the recent changes made to DNG saving code for the Ixus 300 HS are relevant to the S100 inability to save DNG during Hi Speed capture?

I doubt it. But it's easy enough to run the file counter test script and ensure that the S100 is setup correctly. I'll take a look tonight on mine.
