Thanks for the link to an interesting and informative article.

I don't want to get into the weeds and turn a typewriter thread into a photography thread, but there is one small little tiny thing I'd like to add. The technical term is 'depth of field'. Basically, that means getting the front rank of keys in focus as well as the back of the paper bail. The oversimplified explanation is to decrease the aperture size of the camera lens and increase the exposure time of the shutter. Digital cameras do all the heavy work, and in most cases, they automatically focus on the center of the subject and allow the edges of the scene to go out of focus. Not a big deal when taking outdoor vacation photos, and also not a big deal on this Reddit, but sometimes we veer into the technical realm, and sharp closeup photos really help the forensic work.

Like I said, photography stuff. You gotta fiddle with the settings (and possibly add a tripod to your gear), but the way I see it is that this is just another aspect of collector activity. It's all part of the adventure.
