Kathryn wrote about photography, which sent me to find something at Pioneer Woman, and while there I saw something about macro photography which I'd never heard of, but learned basically means "those pictures taken of things really up close."
In googling for that technical definition, one of the search results was for macro images. Wow. This is my favorite so far.
Flikr had some great examples too.
Isn't it neat that we learn something new every day? I feel especially neat that I learned about macro photography.
