Hi Curt,

I am guessing the photo is simply out of focus. I suspect you had the 
camera pretty darn close to the chip when you took the picture.  Many 
basic cameras don't have a macro mode for taking super close-ups.

Generally, if you set your camera to it's highest resolution, then 
take the photo as close as you can and yet still focus, you should get 
a pretty good image.  If the resolution is high, then we can zoom in 
on the image using a viewing program or paint program.  As you 
suspect, the amount of zoom we can do is pretty limitted, but high 
resolution helps a lot.
