Some of the noise appears to look like widely spaced bands, but in other places 
it looks more like blotching. Again, this was shot at ISO 500 and midrange 
brightness was increased a moderate amount. Somewhat less than a stop I'd say. 
(I just did this last night, so I remember. By tomorrow, I'll forget:-). 
Perhaps it has something to do with light angles. It's a mix of direct flash 
and flash off the ceiling. Don't know. But my client will never notice, and I'm 
not going to point it out:-).

----------------------------

At the risk of sounding crass...

Paul, a fat lady in a bowling alley may never notice. The point is not whether 
a client will notice or not. The point is that were the vertical banding to 
present itself in an image that was a wonderful one, one that took a lot of 
effort, time, or expense to make... or one that was a rare image and could not 
be easily reproduced... or one that was going to be printed at a large size and 
for sale... the VPN will have effectively ruined the image.

"Aren't your pictures worth a Pentax?"

A camera that stands to ruin your images for you effectively undoes anything 
else good, first class glass, antishake... you name it. A ruined or compromised 
image is a ruined or compromised image.
