Full size images. One 20 mp and one 50 mp. Large files!

9. Yes, there is definitely more detail in the 50mp image.

Still, even with your enlargement it doesn't come across all that well on a website. It's pretty obvious on a monitor in PS.

That said I took some measurements off my screen comparing the size of the enlargements vs original image. Extrapolating from that the enlargement would be about 50 inches on the long side. So unless the two images were printed to 50x40 the increase in definition wouldn't be visible unless we apply the 'sniff test' (when a photographer gets so close he smell the ink). Normal viewing distance for a picture that large is about 8-10 feet.

Because of the limitations of the human eye 10mp is ample unless severe cropping is necessary. Apple did a promotion for their camera phones by "printing" pictures on buildings. From a block away they looked great.
