It looks like the distance between the A and M look the same as between the M and E, better photos would be needed.
picture actually hurts my eyes go to a better lite area the camera is slowing down the shutter speed which then your hand movement is making things blurry. To counter that, go to a brighter lit area. The brighter the area for the camera sensor (and not your eyes which adjust) then the faster the shutter speed and the sharper the image.
Also, don't put the camera too close. making sure there is ample distance so that it can focus properly. Then crop the image. if you have a camera phone there normally is software to crop the image included. Otherwise basic builtin software will crop if for you on a computer.
No. It's a WAM. Besides just the A and M, look at the designers initials at the bottom right of the memorial. Also, the A in states is centered. In the CAM it will be closer to the second T. http://www.lincolncentresource.com/wideams.html
WAM. You need to study on the differences. Take a good 1991 and a 1993 and study the two. IT will become obvious with what you see different between them.
