Oftentimes, clients request photo resolutions far greater than the iPhone 7 Plus’ 12 megapixels.
My Nokia 950XL has 20 megapixels.
What’s the big deal?
Like most people you mistake megapixels for quality. More megapixels will only allow you to blow up a photo to larger pictures and retain a give quality. . . it does not necessarily make a picture a better photo. For example you cannot pack more detail into a photo of a certain size than the human eye can discern. . . and there is a specific limit for that. Picture quality is measure in arc minutes of acuity and the distance the photo is from the eye, not megapixels. For example a 1080P image is sufficiently good enough for a high-resolution image on a Motion Picture screen that the audience cannot discern a loss of acuity at 60 feet, but the pixels are now ½" in size on a forty-five foot screen! The movie will look the same quality as they see on their HD TV at home at 10 feet.
