title: RGB image captured by Intel realsense camera is dark (using python code)
body: <p>I am using the python code below to take RGB image using Intel realsense (D 435i) camera. The image captured by the python code is dark. However, the image is not dark when I use the camera's SDK. How can I take image with the same quality as the image captured by the camera's SDK?</p>
  <p>Thank you for your help in advance.</p>
