Samsung Galaxy S9 Plus Price in Pakistan
On the Galaxy S9 and S9+, the main rear camera has two apertures, f2.4 and f1.5. The camera is designed to use f2.4 in most situations except when the light goes below 100 lux, which is when it switches to the faster f1.5 aperture. Why not have f1.5 all the time? When you are shooting outdoors in bright light, you don't need f1.5. In fact, having such a wide aperture will result in softer images as well as other issues, such as vignetting and chromatic aberration, all of which have a negative impact on the final image. Stopping the camera down to f2.4 solves all of that, letting you have a sharper image and fewer instances of blown highlights due to over exposure.
In low light, however, the main priority is getting more light on to the sensor. You are less concerned by sharpness, vignetting or chromatic aberration in the dark. In such situations, the f1.5 aperture will work out really well, especially since it's the widest we have seen on a smartphone camera yet. The S9 camera also combines 12 shots in the dark, so any noise or sharpness issues should be taken care of by that.
Now to be fair, the S9 is not the first smartphone to have a variable aperture camera. Motorola was one of the first with the Kodak branded ZN5 back in 2008, which had an aperture that would switch between f2.8 and f5.6. Then Nokia followed with the N86 8MP, which had an f3.2 or f4.8 aperture. And before it ended up on the S9, this same camera system was found on the Samsung W2018 flip phone launched in December last year. So no, it's not brand new tech, especially when seen outside of the smartphone world, but it's very clever and effective, and we are glad to see it make a comeback.

Speaking of things that are not new, the S9 also includes a 960fps slow motion mode. You don't have to go too far back to find the inspiration for this feature; last year's Xperia XZs was the first to include this and it has been part of Sony's flagship line since.
The key to this feature is the inclusion of on-sensor DRAM, a feature of the Sony sensor on the S9 (which is why it was unsurprisingly found on a Sony phone first). It's also a feature found on Sony's range of digital cameras and allows them to capture some incredibly slow motion video.
So, how does it work? Unlike standard slow motion video, say, around 240fps, the 960fps mode does not work continuously for an extended period of time. The camera can only record for one second at a time, during which it quickly captures the 960 frames. That is enough number of frames that, if you slow it down to 30fps, you will get 32 seconds of footage. You can choose how much of the clip is slow motion and how much plays in real time, which will affect the overall length of the clip.
