For interest. Many nineteenth century photos, are very detailed and pin sharp, because they used huge lenses, and big plates. It meant they had very poor depth of focus and the cameras were nearly immovable, but one thing they could do was pin sharp.
How'd they get the cat to remain still that long???
@LucyLoohoo They had to use a really big lens that grabbed a lot of light to get the expossure time down, take ten photos to get one good one, and use a saucer of very expensive fish paste. Sometimes they cheated and killed the cat first.
