title: How to give an image an old, dusty appearance with faded colours?
body: <p>I have images of old paintings. The paintings are old and dusty with faded colours as shown <a href="https://i.stack.imgur.com/xuoEF.jpg" rel="nofollow noreferrer">here</a>.</p>
  
  <p>How do I give any image this type of an 'old' appearance? I couldn't find any filters or openCV functions to achieve this type of look?</p>
  
  <p><strong>EDIT</strong>: My question is different as the other one solves the problem using  the sepia filter and using the grain effect. I'm not looking for that sort of an appearance. I want my image to look like an old damaged painting. This means that the colours should be faded and it should have an overall dusty appearance.</p>
