title: How manage camera shutter speed and aperture in Android?
body: <p>I would like to manage camera shutter speed or aperture in Android
  but I have not found nothing about that.</p>
  
  <p>The problem is this one: I have to take a picture in macro mode with
  flash but with newer smartphones the flash light is too strong and
  the pictures are almost over exposed. I have tried exposure
  compensation calls but it is not enough.</p>
  
  <p>By using the Camera software I notice that the app manages the
  camera aperture, and it is able to take good macro pictures even
  though the flash is forced to on, so I think there is a way to do
  that, can you help me?</p>
  
  <p>I'm using both Samsung Nexus S and Samsung Galaxy W. The white
  picture problems does not exist with Samusng Galaxy ACE: in this
  case seems that there is a kind of an hardware light power
  calibration before shooting.</p>
  
  <p>Thank so much!</p>
