I have a couple of feature reqeusts.... I have asked about this before but something similar to the lens correction that Photoshop has. Although I use a field flattened at the correct spacing on my SCT, the area of flatness does not cover the full frame of my CCD. It seems to me that PI could work out the curvature then apply the inverse to remove it? I know it's not that simple or it would already have been done, but I'm sure a lot of amateurs would use this function, could be pretty much as popular as DBE.
The other one I believe should be simpler, can we have a slider on HDRMultiScaleTransform to vary how much is applied the same as other processes have?
