Trick to low light photography

I tried this technique you posted by holding the button down, not successful yet.
I took this shot using average camera pro. I used the low setting, (took 8 photos) for this shot. It completely eliminates noise. But like I mentioned, the camera has to be still, you can't hand hold it. Here is the full Rez photo:

That is a tip that I never would have thought of.
I always hold the button and release when ready but this is a tip to a lot of people who just tap the button instead of holding and releasing when ready to take the shot.
Helps with blur too.

There is still no difference.
By the way, this scene is what passes for low light? Maybe for a phone camera, but its not sufficiently low enough light to challenge a point and shoot or DSLR.
That does help with stabilizing the camera, but I am talking about the fact that the picture will improve after a few seconds of it analyzing the scene. However, there is no indication that it is doing that so many people will not realize that they need to wait before they take a picture. I tried this dozens of times tonight and you need to sometimes wait about 2-3 seconds after the phone focuses before you see this low light processing happen.
Yes, there is a difference and you're not looking carefully enough. There is definitely more noise particularly on the wall in background.
I found out how it works
Focus on something in low light by pressing focus once, it takes a noisy low light photo.
Now triple press the focus button quickly on the same spot and you notice noise reduction right on the screen.
The moment your phone moves it removes the noise reduction so shoot when the noise reduction is applied
Confirm please

It is good! Make sure you go to settings, scroll down to the app, expand it, and make sure the resolution is set to full. Here is a shot with 32 exposures:

Correct. Just keep the phone still for a few seconds and it will apply the noise reduction. You don't have to hold the shutter button down.
Great find!
I will try this out but for me the phone will apply the noise correction after a few seconds of holding the phone still. No need to hit anything you just wait for it. However, this is obviously confusing since most people won't randomly wait to take a picture when the phone seems ready. The only reason I found this out was because I waited for my friend to stop moving before taking her picture and I noticed that the picture all of a sudden changed in real time. It become less noisy, but it also became less sharp and more stylistic like a comic book.
Also, I cannot make this happen when taking a picture in good light. It only happens during low light conditions where the iphone increases the ISO.
I can confirm Camera+ does this as well, but also only in ISO 3200 mode. It seems this was baked into the API

Holding your finger on the screen just sets the AE/AF mode. I don't think any NR is applied. If you want low light photos, spend .99 and get the app called NightCap. It allows a full 1 second exposure for low light.
I have nightcap, and am eagerly awaiting their 3200ISO update
That being said, I can 100% confirm that both Camera+ and the default camera app will apply noise reduction when held still at ISO3200.
Yes, now imagine that same photo, but at 4x the shutter speed with 3200ISO
That would be cool. However I prefer less noise in my images. But we will have to see how we'll it does. I know there will be noise and these phone cameras will most likely reach their limit. Maybe one day, the images will look as good as some DSLR's. for the best photos, I'll continue to use my Nikon D800/e cameras.
Agreed, which is why this thread is so exciting! It shows us how to best take advantage of the iPhone 5's noise reduction in 3200 ISO mode
To get the effective ISO of 3200 (it's not a true ISO 3200) the camera applies pixel binning. I believe it's a 4:1 ratio, so you're effectively losing 4x resolution, though I'm sure they play some tricks like linear grading over those pixels so it doesn't just look like one big pixel.
