If you're interested in areas of other than news photos, my book covers other areas like cabinet cards, tintypes and postcards. And it does have a section on news photos, wirephotos, etc.
Judging the Authenticity of Photographs (5th edition)
I also have a free
web version. It's an old version, from several years ago, but has the basic info. I haven't updated in in a long time, but old photos are old.
None of my books has been endorsed by PSA/DNA, so that's good right?
