title: Default CSS filter values for brightness and contrast
body: <p>Recently I've updated Chrome to v.26 and pictures which were displayed using HTML5 canvas were not visible anymore. As I found I had to change to brightness and contrast.</p>
  
  <p>How are the values for BC for CSS filters different depending on the browser engine?</p>
  
  <p>Default:</p>
  
  <pre><code>Brightness:  0; contrast 100: Firefox ? 
  Brightness:100; contrast:100: Chrome ?
  </code></pre>
  
  <p>As I found out it is actually a bug fix for Chrome:  <a href="https://code.google.com/p/chromium/issues/detail?id=168004" rel="nofollow">https://code.google.com/p/chromium/issues/detail?id=168004</a></p>
