title: Accessing USB camera controls with AForge
body: <p>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.</p>
  
  <p>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.</p>
  
  <p>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.</p>
  
  <p>Can you help me?</p>
