Recombining Extracted Wavelets from MLT?

How exactly are you creating the individual layer images?  Are you subtracting the resulting layer from the source/original image before extracting subsequent layers?

No - I just disabled all of the layers but one and then applied that to a copy of the image.   I had assumed (I know this is where most troubles lie!) that the layer  thus extracted would stand alone. 

So I set MLT up to work with the number of layers I wanted.
Then I enabled a single layer while disabling all of the other layers.
I dragged the triangle onto a clone of the full image. 
Then I renamed the resulting image for the Layer extracted. 
I did the same with the residual image.


It seemed like this would decompose the image into its individual wavelet layers - and having done this, these could then be recombined to recreate the starting image.   

I have seen people try to do this with the wavelet layers extracted from the ExtractWaveletLayers script - but I understand that this is purely a visualization tool, and each layer extracted is also stretched for convenient visualization. 

However it is obvious that the extracted layers from MLT have no such stretch, so I was expecting a simple recombination was possible.
