I have a project where i need to work with a USB camera to process images aquired at a very close range (under 5mm). Because the space available is very short, I can't use auxiliary lens.

I know I can do some post processing at bitmap level, but I would like to gain access to properties like auto-focus or white balancing at camera level.

I'm developing in C# with AForge for image aquisition and post processing, but I can't seem to find a way to control the camera before the image aquisition takes place.

Can you help me?

After some more thorough research I've found the answer by myself.

If anyone else is searching for this you can try the following;

VideoCaptureDevice Cam1;
FilterInfoCollection VideoCaptureDevices;

VideoCaptureDevices = new FilterInfoCollection(FilterCategory.VideoInputDevice);
Cam1 = new VideoCaptureDevice(VideoCaptureDevices[0].MonikerString);
Cam1.DisplayPropertyPage(IntPtr.Zero); //This will display a form with camera controls

It also seems possible to control these items without the form by using IAMVideoProcAmp
