Set to manual, change the setting in the camera app, and don't worry about the preserve settings because it doesn't apply to this particular thing.

So this was a bit of a letdown. We had the rumors of Apple's going to go to JPEG XL and they did add support for JPEG XL in iOS 18 on the iPhone 16s pretty much only and only for their pro raw stuff. So it's not like geek where they said, oh, by the way, all our cameras take photos in a new format by default. And it's this great new format. They didn't say that they didn't talk about it. at all.

But nevertheless, on an iOS 18, on iPhone 16s only, I believe, because when I was on iOS 16 on my 14 Pro, it didn't mention JPEG XL anywhere. So I think it's only on the 16s. It's definitely not on the 14 Pro. I can tell you that. If you go to the formats section of the camera preferences, you will see at the top...

uh pro default and you you see heath max pro raw 12 megapixel pro raw max up to 18 megapixel and then the next section is pro raw format and your choices are jpeg lossless which they now list as most compatible and then there are two jpeg xl choices lossless and lossy and again that's only for when you're shooting in raw so you can have a lossless raw with jpeg xl or a lossy compressed raw with jpeg xl here's what petapixel had to say about it

Apple has wrapped JPEG XL photos inside a DNG container, enabling ProRAW files to retain their flexibility while being significantly smaller. What would typically be a 75-ish megabyte ProRAW max file will be a 20 megabyte in lossy ProRAW format using JPEG XL compression, a lossless file still under 50 megabytes. Without compromising quality, these are significant storage savings.

So JPEG XL is on your iPhone. If you have a newish iPhone... And if you're shooting in raw and if you are, you can get files that are up to half the size that they used to be at about the same quality. So good thumbs up, but it is not the JPEG XL revolution that we had been waiting for. So I did change to JPEG XL. I think I went with lossless just because I'm shooting in raw.

I probably just, you know, I do it so rarely on my phone. I'll just pay the full cost of the size and it's still smaller than it used to be. So, you know, partial thumbs up on JPEG XL. Hopefully it will expand over the years.

I recall like way back in the PowerBook days, maybe, or maybe it was the MacBook days, there was similar indicator light and Apple made similar claims about how, well, it's impossible to hack this light because there's a hardware feature in the laptops that basically says when the camera is active, this light comes on.

Like this was an example of it not being software mediated at all, but it was something like, hey, if the camera's on, the light's on, there's no software environment. Software has no visibility into the light whatsoever. Can't turn it on, can't turn it off. It's just like an electrical fact of life about how we've connected the camera.

And even when they did that, I believe someone found a way to get the camera to turn on without the light going on. Like hackers are devious. So this exclave is, you know, in the game of cat and mouse, here's Apple's next move. It's like, oh yeah, let's make it even harder for you to get this light. Even if you have kernel access.

You still can't get at this because this is a different OS running in this secure exclave, which is this other little machine that you can't get to. The secure enclave is obviously where you can put secrets that are hard to get to if you're running on the main CPU SoC. But now we have the secure exclave, which is a whole other chip with a whole other OS. It's even harder to get to.
