    You asked for it, so: you're ...

    The first scanners were in use much earlier (about half a century) than that.

    You're thinking digital scanners, perhaps?

    That's how the SAMOS spy satellite systems worked back in the 60s. Also look up the Corona satellites, lots of very impressive pre-digital technology there. I don't remember which systems were actually flown, but there was at least one that did film developing, scanning and transmission onboard. The ultimate scanner... the drum scanner... was initially developed for transmission by radio even before the 1920s.... this wikipedia article can tell you more. The first analog scanners go way back to 1907:

    has anyone got the link to the photog on flickr that the OP was referring to? it'd be helpful (at least for me) to see what they're talking about.

    please

    Let us not forget colour motion pictures. Still photography 'inherited' positive film, then had to figure out how to deal with it (print it).
    Considerably AWOL at the present time...

    The title of original drum scanner probably goes to the first fax machines. Although they were probably not much different to the radio version.

    Yup. I don't know for sure when the modern term 'drum scanner' appeared, but the basic idea almost certainly dates all the way back to cylinder phonographs c. 1880.... Edison and others must have thought of recording images as well as sounds. They may not have thought of transmitting them until a bit later.

    Wouldn't it be cool to locate one of the belinographs and see what kinds of images they produce?! 100% analogue BTW no ADC.... so if I rigged one of those up to my printer, maybe it'd be kosher material for APUG

    In the UK about 15 years ago, there was a TV series called The Secret Life Of Machines. Each episode was devoted to a piece of domestic equipment and the functionality was explained in layman's terms.

    In one episode they discussed the fax machine and the two presenters converted their lathes into a drum reader and drum thermal printer. They were connected via a telephone line and once they had got their speeds the same, they were able to transmit an image from one workshop to another.

    Tim Hunkin (one of the presenters) also makes cameras, some of which record an image straight to Ilfochrome paper: http://www.timhunkin.com/61_cameras.htm

    P.S. Here is an interesting article in the NY Times... from 1921.
