The tulip in the photo must be reflecting mainly red spectrum light to cause this problem which I think is not totally CA. I think it may be that at the transition from red to background the green and blue pixels have no info so register black hence the fringe.
Is this correct and is it the only real problem that digital has over film?
Can it be rectified with RAW processor other than DPP?
The worst effect is when the tulip/red is out of focus(depth of field)
But it still is a problem even when in focus.
Do I just have to be aware of this limitation or is there an easy workaround.
