There are sometimes discussions whether smaller or larger images are more useful. In short, this depends on the application. This page is dedicated to the arguments for larger images.
Info When talking about large images or high resolution here, high detail is also assumed with the related pixel count.
1. Details of artwork or architecture are better visible
Especially with buildings or art, high resolution can be important, for example to get the smallest details sharp and study them. For buildings on facades, older buildings usually have details such as anthropomorphic faces that can be important for studying that style of architecture.
2. "Where was this again?" Or: Evidence that this photo was taken there
During a hectic photo tour of some communities, it is possible to forget or not have written down the exact location of the photo site. At a high resolution, smaller or more distant signs can be read that give clues to the location. This can be important if one needs the location, such as taking photos of the same location over years to illustrate change. It is also helpful to confirm a given location.
The picture example illustrates it: On the sign 310 (place name sign) on the right in photo, one recognizes just so that it concerns the village Trogen. The sign 310 is in the German traffic sign catalog; so the Swiss Trogen can be excluded. Via satellite images, the exact location can be searched with the picture; the road is a clear feature.
3. Maybe it doesn't need the high resolution, or does it? - The aspect of postprocessing
Works with (free) CC licenses allow editing. It is usually almost impossible to predict what subsequent users will need the works for. However, a work of higher quality and resolution allows greater scope for post-processing of any kind. If high resolution is not needed, the image can be downscaled in post-processing if necessary; the other way around, this is difficult or hardly possible (at most via AI upscaling).
4. A small portion is enough: cutting to size
There are application areas in which details of an overall photo are in focus. This is illustrated by the example of the pocket calculator. Let's say someone wants to create a tutorial with the image of the calculator. For the function of the individual keys, he could crop the image to the individual keys. The higher resolution allows it. Technically, it also becomes clear: Suppose there is a relevant detail in a photo (such as a stray cat) that covers about 1% of the image area. In a photo with 9000x6000 pixels, this would be a crop of 900x600 pixels. If the photo was taken with a good camera system, even this relatively tiny crop can be useful. For a total photo with 1920x1080 pixels (Full-HD), this would be 192x108 pixels - this is usually too little.
5. A work by AI or real?
By using ChatGPT as a language model or Dall-E or Craiyon as an image generators, you can have AI create new creative works. However, this can also be used to create situations that appear real but are faked. Well-known examples from 2023 are Trump allegedly being carried away by law enforcement officers or the Pope in a down jacket. If a true image is available in high resolution, this can be rated more real because AI cannot simulate this true-to-life level of detail (multiple real photos of a view are better).
