Raw files (the correct files format differs from manufacturer to manufacturer) are simply a ‘digital negative’ of your image (but aren’t negative at all, only referred to that way in reference to the film era). In Practical terms, a raw file is all the bits of information the sensor captures, packed in one file without any compression or loss. But why would anyone need all that info? After all, raw files are 10x larger than jpegs, right? Yes, and it means they contain much more information. If you edit a raw file and need to brighten the shadows and equally tone
Portrait Mode takes images with a shallow depth of field, focusing on the primary subject and blurring out the background for a professional look. It does this by using machine learning to estimate how far away objects are from the camera, so the primary subject can be kept sharp and everything else can be blurred.
In order to estimate depth, the Pixel 4 captures an image using two cameras, the wide and telephoto cameras, which are 13 mm apart. This produces two slightly different views of the same scene, which, like information from human eyes, can be used to estimate depth. In addition, the cameras also use a dual pixel technique in which every pixel is split in half and is captured by a different half of the lens to give even more depth information.
Improvements in imaging, especially the software, just keep coming. Nokia had versions of this capability years ago. Good to see Samsung catching up.
Samsung’s next Galaxy smartphone could be a huge leap forward in terms of its camera capabilities – at least if early spec promises are to be believed. Photo of Galaxy S10 from Samsung. While we’re starting to get clearer pictures on the future of Samsung and Apple’s future models, we’ve also been here before and know that companies tend to promise everything up until the launch of a new product. After all, they don’t call it the hype train for no reason at all. Early renderings of the Galaxy S11 show one of those ugly camera bumps on the back
It is amazing what you can do with a camera in a Smartphone these days. Don’t think of it as a replacement for a DSLR in hardware, think of it as a vehicle for delivering innovative software features to the world of photography. The Pixel 4 and Nokia products are a good example.
With everyone nowadays talking about computational photography and all that it can do, you know that the engineers at Google will put some magic into that […]
