Open .hdr files with OpenCV
<p>I try to read <code>.hdr</code> files like this:</p>

<pre><code>img = cv2.imread(sys.argv[1])
cv2.imshow('Image', img)
</code></pre>

<p>This gives me a 3-channel 8-bit <code>Mat</code> which is either (nearly) completely white or a very dark picture. So I suppose it only gives me one image of the exposure sequence? How do I get a proper <code>Mat</code> with all the information?</p>
