I mean, that's part of these people giving their experiences and sort of feeling down on this is that, yes, of course, all storage media has some failure rate, but the combination of what these things were used for And how prone they might be to failure resulted in people losing data and remembering it and telling stories about it.

Oh, it isn't just an academic concern or something like, yeah, all storage media fails, but it's not a big deal because by then I had moved on. These people lost data to it. And that's why they remember. Kind of like when we talked about floppy disks, losing data on floppy disks, right? People remember it. It's not like floppy disks were just incredibly unreliable.

They were the main storage media on the computer for ages. But when you lose something, it sticks with you. And that happened with this storage media. to enough people that they remember it. And so, yeah, it gets the terrible grade, the terrible unfair grade that it got.

But you were close. You were close. It was just some of the particulars were slightly off. That's why we'll put a link in the show notes to two things. One, the Wikipedia page on it. And two, a DP review video if you want to see in detail what he was talking about.

I think you did the exact same slightly wrong description as you did in the last episode. I think that's what you just did.

Not quite. But yeah. So we should read this feedback from Sam Doran, who I think summed it up pretty well.

Pause for a second and say what the histogram is. Most fancy cameras have a thing where they'll show you a histogram. Histogram is just a graph that shows, like, how many values at level one, how many values at level two, how many values at level three. And it makes, like, a little mountainous little graph. That's your histogram, right? And what they're showing in this histogram on cameras is...

different brightness levels, with the left side of the histogram being black and the right side being white, and all the values that are in between in terms of brightness, if you're looking at like a luminance histogram, right?

And when I say moving the histogram to the right, it's saying the shape of the little mountain range made by the histogram, you're trying to make the big peak, the big lumpy mountain, be more to the right of the image. The right is bright, the left is dark, right? So it's always going to be some kind of like lumpy type of thing or whatever, but...

If there's one big lump or mound of where most of the luminance data is in the image, exposed to the right is saying, move that lump to the right. Don't leave a bunch of space to the right on the histogram of, like, level 10, 11, 12. These are made-up values. 13, 14, like, oh, those just have very low values on them. The hump is in the middle. You don't want the hump in the middle.
