Klaus,

Are these images superimposable? I'd wonder if one could get some new interesting patterns by mathematical tricks with the layers?

getting those matching at pixel level is very tricky and due to small position changes due to filter change I'd say it will not be doable exactly. Further, the flower also moves towards the light.
