Subject: [Leica] marching ants on the move

Tina...

 

I would wonder if it is something in or on your monitor that you are
seeing.... Since it is impossible for the marching ants to move out of
the circle...

 

I don't see anything.....but we are looking at a sized down and jpeg
version.... You can make just about anything look good in a 800x533
version... they can be way out of focus and they still look good with
slight unsharp mask  

 

Also it looks like a lot more than a 500% crop to me

 

In relative terms....  the crop is 31 x 22 pixels of the original is
800 x 533... 

 

So that's like magnifying it over 25 X  (800/31=25.8)

 

It also appears that the crop was slightly rotated... and that would
mask some of the artifacts as well since you lose some sharpness in that
process...

 

My two cents.
