For me, many things I remember are kind of "photographic". Like if I'm trying to remember something I read, I can often recall where it was on the page, and if a key word was hyphenated (split between two lines).  And I'm pretty good with names, but when I'm wrong it will be because I got it mixed up with another name that is the same number of letters. When I run into someone I haven't seen in a while, in trying to think of the name I might see "(5 letters) (7 letters)" and coming up with the name is like filling in the blank. When trying to spell, I picture the word and just say the letters that are there. The words I spell incorrectly, I can't come up with a clear "picture" for.
Don't know how to explain it, it's just the way my brain works.
