AB  - Extreme ultra-violet images of the corona contain information over a wide range 
      of spatial scales, and different structures such as active regions, quiet Sun, 
      and filament channels contain information at very different brightness regimes. 
      Processing of these images is important to reveal information, often hidden 
      within the data, without introducing artefacts or bias. It is also important that 
      any process be computationally efficient, particularly given the fine spatial and 
      temporal resolution of Atmospheric Imaging Assembly on the Solar Dynamics 
      Observatory (AIA/SDO), and consideration of future higher resolution 
      observations. A very efficient process is described here, which is based on 
      localised normalising of the data at many different spatial scales. The method 
      reveals information at the finest scales whilst maintaining enough of the 
      larger-scale information to provide context. It also intrinsically flattens noisy 
      regions and can reveal structure in off-limb regions out to the edge of the field 
      of view. We also applied the method successfully to a white-light coronagraph 
      observation. ELECTRONIC SUPPLEMENTARY MATERIAL: The online version of this
