Agreed. One of only two circumstances where a filter is really necessary for
digital.
The other is high altitude. As the blue sensors (or blue film layer), can't
distinguish between visible blue and
ultraviolet, there is no way to properly correct in post. Pulling down the blue
channel can help, but there are often
parts of the image that then look off in the other direction. For a really
important image, lots of masking/painting
will likely work pretty well. but it's MUCH more work and less likely to be
right than a simple filter to start with.
BTW, over filtering is better than under. Raising a low blue channel is better
than lowering a UV contaminated one.
