Similar idea to the discontinued Light L16 camera https://petapixel.com/2017/12/08/review-light-l16-brilliant-...

That looks insane, definitely a trypophobia trigger!

This appears to use a naïve masking approach (using ML to find the edges of the mask) which seems to suffer from slight uncorrected differences in lens distortion. There's a fairly obvious feathering around the edges of the detailed area, objects shift quite dramatically, and overall I feel like I'd do a better job of this manually. It is a cool idea, but flawed execution. I would prefer something like using ML to generate a displacement map between the wide angle and the narrow angle parts. That way you can map the higher details down faithfully without having to feather the edges nearly as much or compute any mask. That would also solve parallax which I see also looks unaccounted for.

Weird issue: The iPhone dropdown doesn't include the iPhone XR. It's not like I expect it to work, I'm just curious what the app does.

This whole thing feels wrong. OP should be working for a phone manufacturer, not trying to sell this as a subscription. How much is it worth to be able to squeeze a little more visual clarity out of my phone? Maybe $20 maximum? And I feel like I’m on the generous side of the population here. Most people will say $0. But if you’re inside of Apple and you can tell them you can add an average of $1 of perceived value to each of their millions of phones sold each year they’ll be over the moon and you can get a fat salary.

As an Android guy and not an iPhone, or phone pic guy...

What do the multiple lenses do then, if not this? Like,I presumed that was the point.

Are they LITERALLY just decoration for me to make fun of?

Some older android phones like the Huawei P20 Pro had a combination of 40 MP main sensor and 8 MP monochrome sensor and combined them to produce a better image. But modern phones tend to have zoom, normal and wide-angle lenses which don't overlap in any meaningful sense.

Your idea about combining two lenses to make a better quality image could also be done with a single lens, just taking more photos in a row. Almost all phones (iOS/Android) do this for you already.

Different optical zoom levels.

Many phones already use information from both cameras, too.

Android phones have multiple cameras too.

Normal, wide, and zoomed

This has to be bait right? They’re different lenses with different focal lengths. Same as on Android phones with more than one lens.

Is it just me or do the original photos look better overall?

That's super handy, thanks! I've been using one of those selfie monitoring screens and opening the camera to record video + turning on the flash, this app seems like a better way of accomplishing this

What API are you using if you don’t mind me asking?

That seems super cool! You could almost strap an iPhone to the back of your phone and see yourself for recordings.

Apple’s MultipeerConnectivity framework -- phones discover and talk over local wifi / bluetooth via MCSession, MCNearbyServiceAdvertiser, and MCNearbyServiceBrowser in PeerSessionManager.

Apple has deprecated all of that now

You're right - I have to move them to Network Framework when I have time :)

When you get around to doing that, you might find the Github repo and its accompanying medium article useful.

Nice! I was really missing working examples when I replaced an MPC by the lower-level Network, not an easy task, but it provides huge improvements

Please post your own Show HN, or comment in “what are you working on” threads, or pick some other approach.

I also have an app that uses device camera and I don’t write about it in mostly unrelated submissions.

Not just the app idea … but the WEBSITE — is VERY WELL DONE.

I immediately signed up. (And offered to help bring users to this thing.)

Thank you very much, that's really appreciated! Just added all the new sign-ups to the TestFlight, looking forward to hearing what you all think.
