Maybe this only works on certain fish, but if you stop the first long cut just short of the tail you can flip the fillet over and it stays connected to the body, making it easier to hold while you cut the fillet away from the skin.

The Sony Mavica FD91 was the first digital camera I ever owned! I used it the last couple years of high school and during a short homestay in Japan. You could pick up a giant box of 3.5" floppies for cheap, and as long as you fed it a stead supply of batteries it worked pretty well.

Here are some photos I took that are at, I believe, the highest quality setting (1024 x 768 and about 170kb each). Though I think Lemmy shows them shrunk down in the feed, if you open the image in a new tab you can see the full resolution.

Zoomed in.

And a closeup.

The 14x optical zoom was pretty amazing back then.

A similar machine also plays a role in the 1997 movie Contact.
