LESSON #9 -
The OFF CENTER
This seller tried very hard to keep his dirty fingers out of the image as evidenced by the correction he made in his technique when imaging the back.
LESSON #10 -
The PHANTOM SLAB
Probably not worthy of inclusion in this course, but it almost looks like the seller is holding a raw card behind an empty slab to make it more desirable. If that were the case, his choice of GMA misses the mark.
I'll keep this lesson short as it may be a snow day for some of you.
