Some cameras, might use Pixel binning which combines all the information in four adjacent pixels to produce one,  or they can simply drop enough pixels using only the color information to get to 6mp.    Since 16mp doesn't come that close to being 4x 6mp, (I'd have to think about the math and

I remember setting my K7 to 6Mp to compare with my K110D (max 6.1Mp). I could see no difference but the K7 files were considerably larger than the K110D files. I'll repeat the exercise later today with the K110D & the K5 (sold the K7) & post the images & stats. Alan C On 05-Jul-18 11:22 PM,

some 16mp cameras have a 6mp shooting mode, I assume its downsizing. On Fri, 06 Jul 2018 00:39:08 -0400, John Sessoms wrote: I'm not sure I understand what you're asking for. Do you mean 16Mp images downsized to 6Mp? Or do you mean there's a 16Mp camera with a 6Mp crop mode? Or

I'm not sure I understand what you're asking for. Do you mean 16Mp images downsized to 6Mp? Or do you mean there's a 16Mp camera with a 6Mp crop mode? Or something else? Downsized images might appear sharper depending on the algorithm used to downsize them. On 7/5/2018 17:22, J.C.

are the photos from a 16Mp DSLR set to the 6 Mp setting sharper than a 6 Mp DSLR running at full resolution? My hunch is they would be but has anyone ever tried this or a similar comparison? -- J.C. O'Connell hifis...@gate.net - Using Opera's
