You might not think much time has passed since you last went down tot he photo store to deliver a few rolls of film, but a generation has grown up since without any idea of non-digital photography.

In this video by YouTube channel the Fine Brothers, children are introduced to old technology, and left to their own devices to figure it out.

The oldest seems to have a vague and distant memory of film technology, but the rest can hardly conceive of opening the camera, never mind leaving the house to get the film developed.

One girl is disgusted that she has to wait to have the picture printed before she can view it: "Your're not making me walk to a store now are you?"

If you wanted to feel old today, then this is the video for you.
