;
; script-fu-dynamic-range-extender - A script that will produce an image
; with extended dynamic range. The input is an image with 2 layers, lighter
; (eg. exposed for sky) MUST be the lower layer and darker (eg. exposed for
; shadows) MUST be the upper layer. Please note that the upper layer must
; be anchored, floating selection is not sufficent.

_"_Dynamic Range Extender"
_"Blend two differently exposed images together thus increasing dynamic range. Image must contain 2 layers - lighter (eg. exposed for shadows) MUST be the lower layer and darker (eg. exposed for sky) MUST be the upper layer. Please note that the upper layer must be anchored, floating selection is not sufficent.\n\nBlur strength controls the amount of gaussian blue applied to the mask. Different values are suitable for images with variable amount of details. Opacity is the opacity of the darker layer with the mask, usually 100 is just fine."
