Sounds like what I'm after, but the price is a little steep given how often I'm likely to use the package. I'm finding that de-rotating and registering the images requires only about a minute per frame. Iteratively adjusting contrast and color balance to give each image in a series a consistent background take a lot longer. Even though the 15-frame series I'm presently working on covered only about 1-1/2 hours in time, the color and intensity of the scattered light changed considerably. I'll save the 39-frame sequence I shot last week for another day... Thanks for the reference. -- Mike -- -- cal_donley@xxxxxxx -- See message header for info on list archives or unsubscribing, and please send personal replies to the author, not the list.
