I am a bit confused about the meaning of MP for cameras in smartphones.
I have a reflex digital camera with a 24 MP sensor, which gives me photos of 6000*4000 pixels, up to 12 MB of file size (jpg), and this is exactly what I would expect from a sensor like that.
All the smartphones I had so far would say they have 40 MP, or 80 MP, even 108 MP, like the one I currently have. As for this last one, it was advertised as a very good camera phone, with so many pixels to give back wonderful photos. Nonetheless, the photos I take with those smartphones are small sized, both in file size and in MP. For instance, one of the last photos I took with my phone is 4000*1800 pixels (equals to 7.2 MP), file size 1.9 MB. And the quality, well, quite disappointing, very little details and if I zoom in on the display, the photo gets blurred.
Where have the other 101 MP gone? Can you help me understand?
I also thought the very high number of MP in my phone was for the digital zoom, so that the camera could zoom in 6x and still have a good resolution photo. The reality is that if I take a photo with the zoom at 1x, the photo is rather good, but gets blurred if I zoom in on the display. If I take a photo with the zoom at 2x, the photo is still the same file size, but the details are gone. So, it doesn't seem that those MP are being really used.
I'm attaching the last photo I took this morning, one of my feral cats while she was waiting for her morning meal. One is the original file, the other one is a cropped photo. You can see how bad they are. Those photos are actual size, not resized, to let you appreciate them fully.
