How do I tell what type photo this is?
I've searched the blogs and wasn't able to find any definitive explanation of how to tell what type a photo is. I'm posting here. The back is blank, the front is glossy, the detail - even enlarged - is sharp. (I've also searched the internet for images and can't find a similar one.) Probably a dumb question, so please excuse me asking, but thanks for any input.
