What will you achieve by using the default option of a very high resolution? As it seems, there are some minor issues. The highest resolution image does not show necessarily more detail, on close inspection, and may exhibit whitish fringes near the edges of objects. This is due to heavy contrast enhancing processing that leaves such artifacts, reaching an image that is not better from a lower resolution one while it occupies more storage space and makes editing slower. | What will you achieve by using the default option of a very high resolution?

The best approach is to evaluate, separately, each resolution and format, on the same scene and subject, to determine which one works best. A common approach is to notice the format and maximum resolution, let's say 3 | The best approach is to evaluate, separately, each resolution and format, on the same scene and subject, to determine which one works best. A common approach is to notice the format and maximum resolution, let's say 4:3 aspect ratio and 64MP and 9268x6936 resolution, and go for the one immediately below, 3:4 aspect ratio and 16MP, 4624x3468 resolution. The so-called full resolution, has a 4:2 format and is 4624x2084 and the 16:9 one is 4624x2604. In this vast array of possibilities I would suggest the 4:2 or 4:3 format, since it has the lowest resolution while it is still higher than a 16:9 1920x1080. The reason is that with slightly lower resolutions the camera has a reduced risk of post-processing, and more useful information is received by adjacent parts of the sensor, reducing artifacts. | ||
Although it is counterintuitive, I generally suggest not pursuing wide image formats such as 16:9 unless you really want to showcase landscapes. In most cases you need useful pixels on a slightly narrower framing, particularly with persons, so the best choice would be a 4:2 or a 3 | Although it is counterintuitive, I generally suggest not pursuing wide image formats such as 16:9 unless you really want to showcase landscapes. In most cases you need all the useful pixels on a slightly narrower framing, particularly with persons, so the best choice would be a 4:2 or a 4:3, with the 4:3 having the best prospects. Always keep in mind where the wider part of the picture is, when framing, although all camera applications will easily hint that this occurs in the horizontal orientation of your phone. This gives you the best chance at taking the best shot with your camera. | ||
<code>''Understand what formats and resolution capability your smartphone camera exposes. In most pictures you benefit having more useful pixels in a slightly narrow picture frame, so a 4:3 aspect ratio works well. Always avoid the super-sampled or maximum resolution of the camera in your app as it is severely processed.''</code> | <code>''Understand what formats and resolution capability your smartphone camera exposes.
