Just introduced Galaxy The S23 Ultra is supposed to be a photographic pinnacle. After all, it has all the prerequisites, the main one of course being the 200MPx sensor. It is true that in most cases you will rather use its pixel stacking function, but you will certainly find situations where full resolution is useful.
If you want to get as much detail as possible from the scene, then it is convenient to switch to 200 MPx. If you don't know how, here's a simple guide: In the upper menu bar click the format icon. By default, you will probably have a 3:4 label there. Here on the left you will already find the option to turn on 200 MPx, but now there is also the option to take a 50 MPx photo. And that's it, now all you have to do is press the trigger.

If you are from new Galaxy S23 Ultra excited precisely because of its 200MPx camera, with which you will mainly want to take photos at the full resolution of the sensor, you may also be interested in the question of how large the photos it produces are. This may be mainly so that you know what device storage to actually choose (there are 256GB, 512GB and 1TB to choose from). When we had the opportunity to touch the phone, we took a few photos at the maximum resolution. Metadata reveals that of course it depends on the complexity of the scene. The simple one does not need to take much more than 10 MB (in our case 11,49 MB), but with a more demanding scene, the storage requirements increase, so you can easily reach twice as much (19,49 MB).
Then of course there is the question of RAW photography. Apple The iPhone 14 Pro has been criticized a lot for the fact that in order to take pictures with its 48MPx camera, you have to do so exclusively in RAW. But such a picture will easily take up to 100 MB. When Galaxy The S23 Ultra can therefore take photos both in .jpg format, when you move in the lower tens of MB, and in RAW, saving the .dng format. In that case, however, count on the fact that you will easily get over 150 MB.
Why such a distinction? Is anyone going to take pictures on billboards with it?
Primarily no, very few people will actually take pictures at 200 MPx. Usually, there will be pixel merging, so the resulting photo will be significantly smaller, something like 12,5 MPx.
Depending on how many pixels will be merged, the size of the resulting photo will be.
Why are there so many MPx?? No use for you. But a normal user will be glad for that option (better than not having it), and if you don't know what it can be used for, just ask google
with such a high resolution, the details can be seen much better with a large zoom...
(if it was useless, critics would immediately write it off and manufacturers wouldn't put such resolutions in mobile phones...)
