How many megapixels are good for a camera?
The general rule for high quality sharp prints is 300 pixels per inch. So an 8x10 inch print needs 8x300x10x300 = 7.2 megapixels. One can still make very nice 8x10 inch prints with less megapixels, but the lower the megapixel count, the softer the image.
While The Verge claims that the S8 uses exactly the same 12-megapixel rear camera as the S7, though with software improvements, a report from PhoneArena claims that the phones carry new, custom camera modules. The front-facing camera was upgraded to an 8-megapixel sensor with autofocus.
- The Samsung Galaxy S8 has a 12-megapixel camera and an 8-megapixel front-facing selfie cam.
- But, really, we're obsessing over your camera, S8. Because it does everything we want it to – and more. The S8 has a dual-pixel 12MP camera with F/1.7 aperture, with an 8MP front-facing camera (which also has F/1.7 aperture).
- Instead, it's the camera lenses and the quality of the sensor that captures light to convert into your photos. An 8 megapixel photo from a high quality lens and sensor combo will look much better than the same photo from a 12 megapixel image shot with mediocre lenses and sensors.
