title: How to read .tif image in OpenCV
body: <p>I want to load and display a .tif image in OpenCV Python. I load the image using cv2.imread('1_00001.tif') and then I display it using plt.imshow(img), but the image displayed is all black instead of what it was originally.</p>
  
  <p>I can load and display the image correctly using PIL's Image.open() and matplotlib's mpimg.imread() so I think it is a cv2 specific problem. However, I have also successfully displayed .jpg and .tiff images using the same cv2.imread() function so it may also be a problem with specifically that .tif image.</p>
  
  <pre><code>import cv2
  import matplotlib.pyplot as plt
  
  img = cv2.imread('1_00001.tif')
  plt.imshow(img)
  </code></pre>
  
  <p>I expect an image of a circle with a few blurry lines inside, but the actual output is just a black image.</p>
