Most SDM code is common to all cameras.
Some is common to all 470's and some is particular to 101b.
Comparing the A470 code with the CHDK version then everything looks fine, taking into account the changes for SDM.

So  ....

Format your card, make it bootable, download SDM A470 101b again.

If That does not work, replace DISKBOOT.BIN with the CHDK version .
(unfortunately, you have to enable Javascript to download this) :-

Let me know what happens.

Thanks for all the help, David.

First step, I downloaded the common files, and the A1.01A/1.01B software from Masuji's site again. Tried once again to install, but the cam came up with the same message, 'memory card error!'.

Second step, I downloaded the CHDK software from the site you provided, replaced the SDM version of the .bin file with the CHDK version. I downloaded the files to the SD card, locked it, and booted the camera with it. It seemed to work, but showed, very briefly, a red rectangular message about CHDK, but it was gone before I could read it. This time, though, there were new icons, with a % battery guage for example, at the top of the screen. This, I assume, indicated that the CHDK software was now running.

Can I assume that any functions of SPM now work, accordng to instructions? The camera I set up with CHDK was the right-image one, so would the expected flash ratio of right-camera-normal, left-camera--4stops work now?

It looks good, but I still have to make my cable. I have a 3 - triple-A battery pack I could use, but I'm thinking the amperage might be too high, and I should use 3 button cells instead. I'll be hitting the dollar stores after lunch :-)  I'm in Montreal, so it's only 10:50 a.m. here.

Thanks again. I'll give you an update after I have everything set up.

BTW, I just joined the Yahoo SDM group. I'm 'centennial3d' over there, also in stereo3dXchange and photo3D groups.

Hi Brian.

The file may be corrupted.

Try this version http://www.zshare.net/download/6775893116f4b00b/

You cannot do what you want with CHDK.

Anyway, if there is a problem with the SDM A470 101b build then it neds to be fixed.

Hello, David

Thanks for all the time you're spending on this. I've downloaded the new file that you had linked to, and SDM seems to be working now on the 'problem' camera. A blue banner comes up, Stereo Data Maker ver 1.82, and a menu bar at the top with a battery meter at 100%, zoom:30, and synch 0.0000. I can access the SDM menu from Print/Menu.

Now to build the cables - you had said that 3 AAA cells are O.K? I have the battery pack from a 9LED flashlight, and a momentary NO pushbutton switch, with the 2 USB cables that came with the cameras (I have 2 others when I need them for 'normal' use. I have put together a bracket to hold the 2 cameras in 'portrait' mode, with a lens-to-lens separation of 2.75 inches. Almost ready to go!

Many thanks, again.

Brian

Hi Brian.

Must have been a corrupted file.

SDM 1.82 is in development and has not been released yet.

Any questions or problems, do not hesitate to ask on the Yahoo SDM group.

In ALT mode, pressing left/right buttons displays various shooting aids .. but that is another story.

For now, just press your switch.

Most useful mode is a quick on-off to autofocus and then an on/off to shoot.

From the Stereo menu you can choose an alternative mode where second on-off cancels autofocus.

4.5V is fine, even 6V will not damage the camera.

Hello again,

Now that I powered up both cameras at the same time, I noticed that my other camera, build 1.02c, has a red menu bar at the top, whilst the 1.01b had blue. In addition, the red bar reads "Synch:", with no number after it. I assume that this is not normal. Running through the menus to STEREO -> synchronisation, all settings on both cameras appeared to be the same.

The left camera, that will dim its flash by four stops.

the 1.01b had blue
The right camera that will dim its flash and will fire after a delay that depends on shutter speed.

the red bar reads "Synch:", with no number after it.
The left camera dimmmed flash is immediate, there is no delay.

I assume that this is not normal.

According to the documentation and website it is completely normal.

Thanks for putting my mind at ease. I hadn't noticed the details you described.

Next time you hear from me, I'll have pictures to post on Yahoo :-)

Cheers,

Brian

I should have said that the right camera does NOT dim its flash !
