No, these cannot be controlled via WIA.

Is there a way to change the Picture Control Using the Script?
I would like to change Vivid to Black and White
I have one Nikon D80
Thanks

Toby, I’m sure glad you worked that out because I had NO idea myself!

Okay, figured it out – the camera has to be set to an exposure that will take a decent picture. If the “?” is flashing on the info display, the camera will block the shutter (just like it does . Make sure the camera is set to a valid exposure and the script works fine. Cool.

Raymond, no go, having an image on the card didn’t change anything.

Thanks – yes there was a formatted card in the camera, however there were no images on it. Being a linux user also, I got camera control working using gphoto2 (www.gphoto.org) so I know the camera is okay. I’ll try the script again with images present on the card.

Toby, is there a card in the camera at this point? If so take a shot manually (disconnected from the PC) then run the test script again — it should show that existing image as an “Item”.

If the camera goes “clunk” then you are 99% of the way there, unless the card is missing or not usable (not formatted?) I can’t see what can be wrong.

Update – on Vista, I get a dialog box that says “device may not support shutter release from the computer, use camera shutter button…” when I open up DIYcamera control 4.0. Any ideas?
Thanks.

Raymond, being somewhat of a geek also, I downloaded your script to try with my D40. But I must one of those with a broken setup on my PC (XP SP3). When I click Shutter release, the camera goes clunk and no shot is taken.
If I change the dial between M,S,A,P and refresh the page, it detects the change in the Controls options.
If I do Start Tether and then click Shutter Release, I get script error, line 157, char 2, index out of range.
[I upgraded to firmware 1.11 but no change]
I ran the WIA test script and the results are pasted below. When it runs I get OLE error 80042002 when it tries to take the test picture.

I’ll try on a different PC in the mean time.

Thanks – this will be great when I get it working.

Hey,

Tried it and let me tell you its nowhere close to an embarrasment. Evrythings working good. Played with shutter seppd. Will try ISO and in sometime. I have a D40 so I guess exposure comp wont work.

Controlling shutter/aperture from computer is really helpful

Thanks a ton,
Jinesh Mehta
