PhotosPixel count

Just curious, some of Dana's photos have a pixel count of more than 200 mp! Are these stiched photos?

I cannot imagine why anyone would stitch together a photo that is 95% fingers and background! At least they are clean fingers.

And the fingers are nicely in focus !!

Most possibly they are run through one AI Upscale Software to lift up quality !

Elmar, I think you hit the nail.

What is anyway the meaning of using 200M for this photo? To reduce the space on the Mindat server? 🤔

We as well have 100-MP photos of awful quality from chinese smartphones.
Probably such photos have to be downscaled on upload, I will think about how to implement that and not damage true 100MP+ photo (stitched or from high grade cameras).

There are quite a number of modern phones that have a 200mpx sensor, including the Samsung Galaxy S23 Ultra and S24 Ultra
