Warren,
I don't recall seeing the turn off all the small layers first approach in your tutorials.  But my real question is; why do you get different results?

Thanks,

Thank you Alejandro.

ca you explain why  do you avoid rescaling in the sub level recomposition and instead flag rescaling in the last sum, to recover the original image?

Thank you!

Hi Andrea, you can go and back without rescaling (make a simple test subtracting and adding again only once) and you will regenerate the image with the same minimum and maximum values, but when you apply any process to any of the layers you have separated, then you may need to rescale at the end to have your values between 0 and 1.
