Beautiful app, jpap. Well-done! I can't wait to do some side-by-side comparisons between this and video stills, and see what kind of image quality differences there are. My overall impression of the app itself is that it's incredibly solid. Keep building apps!

Thanks!! :D

Would love to see some real world comparison examples. Drop me a line when you've got something, would love to check it out. :)

Bug report -

On the first launch, if I quickly press the Setting button (bottom-right) it starts the flip animation and still shows the handwritten overlay explaining where to tap for manual focus and all whatnot. After the animation is complete, the overlay is still shown, so it looks like a mess. And it's also not obvious how to get the overlay back, because I haven't seen what it actually said.

Congrats on the TC cover and a very nice app. Get rich! :)

(edit) A nitpick - "Warm-up", not "Warmup"

(edit) Report Usage = On. Seriously? Who on Earth in their sane mind would actually want this, except for you? Next thing you tell me is that you have some "app analytics" library linked in and it's always on. Please don't be evil.

(edit) The same goes for "Send Crash Reports = Always". It should be "Ask". Respect your users and they will help.

That's a really interesting machine vision problem and a lot more complex than a JPEG codec. :-) I wonder how long before we start to see Kinect-like infrared cameras mounted on phones to make the depth problem easier to solve. That would be cool!

I want to see if you could use all the rapid frames, plus a variant of that cool Adobe image de-blurring tech [1] that was shown a while ago to produce a clearer, sharper image during motion? [1]: http://prodesigntools.com/photoshop-cs7-image-deblurring.htm...

There's still much innovation left in image signal processing... and fortunately much interest in taking good photos!

This reminds me of research into superresolution, an area that's "super interesting" :-) as well.

The guys who started Occipital (360 Panorama), I believe, tried to dabble in that with ClearCam many years ago... but I honestly don't know much about it. Anyone from Occipital here on HN?

What's the breakthrough? My GoPro can take 120 photos per second.

Futhermore, what happens if you point this at a device that can affect each pixel on the phone's image sensor 20 times a second? Is all the information preserved? If so, this is an interesting hardware hack. If not, this is an interesting shell game. But I don't see how it's a scientific breakthrough.

(It sure is good for sales when TechCrunch prints your press release verbatim, though!)

Amazing work, and the living photo thing could be a hit.

Out of curiosity and a bit unrelated, I've been craving for real raw capture on the iPhone (before bayer interpolation, white balance, noise removal). Is it possible?

Thanks for the suggestions:

1. Looks like a race condition for the settings button tap. Does it happen if you wait a second before pressing the settings button?

2. You can re-enable the tutorial (overlay) screens from the bottom of the settings menu.

3. On the usage/reports, I hear you. I won't give you bullshit on "standard industry practices" here, but I will say that I had to hack a well-known closed-source library to give you that opt-out from usage reporting. I really do value your privacy. (I've already requested the library developer fix it, and will try and write a blog post on how other developers can provide a kill switch, too.)

4. The default is there because many people don't like to configure apps, they just use them as-is. In that light, the default configuration is the one I felt was best for general use.

This is neat tech and works pretty much as advertised, but man, this UI is pretty rough. The blue background and curvy borders are strangely superfluous; tapping the left-bottom corner controls pops up an intermediate selector but the right-bottom controls work in-place; taking a shot produces a big "infinity" symbol that fades in and out of view -- I don't know what it means. Good work on tech, please hire a UX spec…

Fair comments, and much appreciated. I did all of the graphics design myself, in the app and on the web. :-) The infinite sign you see does require an explanation. I'll take your advice and think about how it can be done more simply. It's basically telling you, the user, that the capture buffer has filled, and you're now dropping (some) shots.

Man, I hope I'll know as much as you do one day... Congrats on the app! I just bought it and I'm really liking it! One suggestion; would outputting to a gif file be too difficult? I could really see people using this to create gifs of their lives that they could share to Tumblr or Facebook.

Thanks! :-) To be honest, none of my formal training prepared me for what went into SnappyCam---only the "how" to go about learning to do so. I'm sure you could pick up a few tricks in the same way by working on a cool pet project or two. With so many recent requests for AGIF, I'm absolutely going to add it to the app. (It's been on my list for a while, but lower priority than getting up a solid core product and the…

Out of curiosity, what kind of educational background do you have if you don't mind the question? As a highschool dropout it interests me. :)

"Ask" should be the default, I have to insist.

Just tried the actual functionality and it gives the machine gun sound effect, showing a counter going up to 50-60, then I release the button, the blue stripe around the button shrinks back, it adds a photo to the bottom-left area, but when I tap it, there are just 3 frames. What am I missing? Is it adaptively trimming bad frames (I am shooting in a low light conditions)?

(edit) Just tried again and this time after I release the shot button, it showed a big circle overlay with the "JPEG" in the middle that counted up to 100% and the resulting photo had the right amount frames. It didn't do that on the first try. It's either a bug ... or you are missing a helpful hint that explains what's going on :)

It may not be possible, even for Apple.

If you have a look at the data sheets, for example [1], you'll see YCbCr or RGB output formats being listed.

I guess it would make sense for as much signal processing to be done as early in the chain in the interests of lowering power consumption. (Less data to transfer over a serial bus into more circuitry, at the very least.)

(Sony also make the sensors for Apple, apparently.)
