I think the preview is calculated on the base of a reduced photo (the 
preview), but in the end of course it's applied to the original image.

The smaller preview has different information (many smaller parts 
falling out...) and so the effect on the high res can differ very much, 
especially with effects that depend on "pixel neighbors"...

To my opinion this cannot be avoided unless the app would calculate 
already the previews on the high res file, what would consume too much 
time.

So the preview in these cases can only give you some idea of the "kind 
of effect" the filter produces in general and in what kind the settings 
will affect, but in the end you simply have to try: say ok, discard the 
result, try with different settings... etc.

If my explanation is not correct, please rectify. dear digikamers :-)
