Hi, I was having a hard time to take good pictures using Virtual Camera and I guess I've discovered some undocumented stuff:

1- my pictures were coming dark and after inserting a "Wait" command they improved a lot

Code: Select all

  cameraControlDo "myFirstCamera", "takePicture"
   wait for 1 seconds

2- my pictures were coming out of focus, so I tried

Code: Select all

cameraControlSet "myFirstCamera", "autofocus",true

and it seems to be working, at least the IDE doesn't throw any error.

Is it possible or am I hallucinating?

Any other hidden controls?

: Real Camera: iPhone Camera

: Virtual Camera: no Wait & no Autofocus

Thanks to Panus from LC Support mystery was solved / fixed. In his own words

1. You create a camera control and take a picture instantly, without allowing the preview to appear
2. This results in very little light (from the objects you are targeting) coming through the camera (the camera’s sensor is photosensitive, see http://www.whatdigitalcamera.com/techno ... work-60565)
3. So the pic is dark.

So, by adding a "wait" command, you allow the necessary light to be collected in the photosites, so the resulting picture looks not dark anymore.

I guess something similar happens when you do:

cameraControlSet "myFirstCamera", "autofocus",true

There is no such camera property, so this causes an internal error and a small delay which gives the camera the time needed to collect the necessary light.

Best regards,
Panos

I still think the IDE should give an error about the no supported "autofocus" camera property....
