Even though I maintain to this day (2025) that photo resolutions of over 12MP are 'over the top' for 99% of people's needs, I have to concede that Apple's implementation in 2024 of 24MP 'Fusion' images is impressive and does work well. If the extra file size doesn't bother you, then it does give enough resolution margin of error to downscale or crop or process later, as needed. (Note that this is all aside from my favoured technique for important shots on the iPhone 'Pro' models, which is to use ProRAW, giving all the HDR and texture intelligence but without sharpening and edge enhancement, at the expense of huge file sizes, over 20MB per image.) Apple's idea stemmed from looking at the two alternatives from its 48MP camera sensors: a pixel-binned 12MP shot, with lower digital noise and greater 'purity'. a full resolution 48MP shot, with higher native resolution but more noise and more uncertainty at the pixel level. So I guess someone at...

It remains a mystery to me to this day. Why don't other phone manufacturers and their cameras use the tricks that Google pulls off? An issue of patents perhaps? Or just lack of software expertise? Regardless, the two 'tricks' demonstrated here are Sensor Fusion and Super Res Zoom. You'll find them on any Pixel in various combinations. On the Pixel 7 and 8 Pro and on the Pixel Fold (below) you'll find both techniques employed. And yes, I already said that most people don't need to zoom more than 3x in normal life , but hey - this is for when zoom is needed. Perhaps at a sporting event or trying to spot rare wildlife. To demonstrate both tricks, let's take a standard landscape shot - with an interesting central subject: So far so good, and any camera phone could take this shot. Here scaled for the web, but don't worry, I'll show off some crops below too. Now we try zooming at 2x: In the case of my Pixel Fold, the main sensor is 48MP, so a 2x zoom smart...
