Problem with Xperia Z1 Camera

andrei_ghi — Sat, 10 Oct 2015 05:04:01 GMT

Hello,

I recently bought a Sony Xperia Z1 and I have a thing I wanted to know, not sure if it's a problem.

When I try to take shots at night, before I press the shutter button the whole image looks very grainy. When I actually take the shot it comes out ok.

What it bothers me is that it's a big difference in quality between what appears on the screen before I take the shot and the actual picture which is ok. Is that normal?

Thank you very munch in advance. Hope I made myself clear.

That's normal, are you using manual mode or superior auto?

Uliwooly posted about that, it's called pixel binning

Importantly, the Z1 shares a key technology with the Lumia 1020 in the form of downsampling. Whereas the Lumia creates downsampled 5-megapixel still images from its 41MP sensor, the Z1 uses similar mathematical techniques to produce 8MP stills from a 20MP image. And although the sampling ratio is smaller, the impact of Sony's "pixel-binning" is immediately visible and beneficial. You lose resolution on your final image, of course, but you also lose lots of nasty image noise.
