Here's how to lock exposure:

I take a lot of 3d photos and videos. The difference between them, and 2d photos and videos is profound.

On viewing, with a suitable tablet, tv or yes, lenticular print, you are immediately transported back to that moment when you captured it.

Surprised you've never covered the topic here.

I'm crap at a lot of things. But I'd rate myself in the top ten globally for expertise in all things 3d. Hard won experience all gained to bring joy to my wife. She adores 3d. So that's why I perfected the tech for us.

"Grandpa! Don't make my photos all gray!" Sorry, Alice, Grandpa can't help himself. She's only 6 years old. She'll come around.

There is an excellent iPhone app called Halide that opens up all the available photographic controls of the camera as well as the ability record RAW files.

In case this is another helpful hint, you can actually trigger the shutter using the volume buttons instead of the on screen ‘dot’. Helpful to maintain that good grip!

I have found a middle-ground with my phone that I am much happier with. It won’t be for everyone, as I am firmly in the “good enough” camp, not seeking high-megapixel technical perfection. Other indicators that you may not be interested are that I typically carry Micro Four-Thirds instead of my full-frame DSLR for intentional photography.

Since my iPhone 7 Plus and now on my iPhone XS Max (both acquired used many years after introduction), I use ProCamera to capture DNG raw images. This offers me more manual controls, jpeg files for immediate sharing, and the ability to use DXO PhotoLab later on. The manual controls do honor my intent pretty well.

In PhotoLab, I can run the same workflows as I do with my dedicated cameras, including exposure, tone mapping, white balance, etc. with the AI noise reduction (Deep Prime), I get quality somewhere between where the Nikon D90 and D70 were back in the day. There is still some exposure latitude in those raw files.

Note that PhotoLab does not support my iPhone XS Max directly, or indeed any modern iPhone. I need to use exiftool to change the DNG to say it is an older phone. Overall, it is automation-friendly and worth the hassle. I am aware that newer iPhones emphasize ProRaw, which will not work with this approach.

I don't use camera phones much, but in low light isn't it difficult to not cause shake when tapping the shutter "button"? That could be a good use fo voice command. You could whisper "shoot" to the thing. Can they be trained in that way?

I found out an hour ago that there are apps to control video on smart phones that are pretty comprehensive.

Using the volume keys to shoot the camera is standard on Android phones, and is vastly better than trying to get a finger to the screen.

My dogs never told me about the potty privacy rule. I have a few shots of them doing their business just for the comedy of how they balance with #2. My wife is not a fan of those photos for some reason. I should make a calendar.

The volume buttons will both trigger the shutter so you can squeeze the phone much like a proper camera's shutter button.

My problem with controlling highlights is that if the Sun is already too bright, I can't really see the screen well enough to find the little Sun image when the AF/AE lock is on. Fortunately, it is not necessary as once locked, any adjacent spot on the display acts as the slider. Because of reflected brightness, I still wind up with a "best guess", but sometimes that is all you get.

one reason to think about buying a sony phone of recent vintage is they all come with a dedicated shutter button at the right hand side. sony Alpha camera users have some cool integrations with that ecosystem. a bonus feature is if you're doing anything else that shutter button immediately launches the camera app too.
