Was the video/photos taken during the earth-rise on the Apollo 8 flight the first "blue marble"-esque photo? I've heard the image equated to the "earth's first selfie" and question the technical accuracy of that premise.
*Note to pedants:
Seeing other similar type questions on the site, please understand the concept of what I'm asking, if not the accuracy. Yes, you can only take, at best, a photo of only half the earth at a given time, and yes, during Apollo 8 the Earth was partially in shadow....
