Tony Northrup - The TRUTH: Hi Megapixels + BIG Prints are a WASTE?

Tony Northrup just posted a video titled: The TRUTH: High Megapixels + BIG Prints are a WASTE? iPhone vs Sony a7R IV vs Sony a7 III

Interesting comparison.  And he did come to the conclusion that to make big prints, that the number of pixels did matter.

I would like to see another twist to this test.  And that would be to use a similar panel of judges to look at images the same way, but to add another category.  I have been playing around with resizing SW and have compared ON1 Resize, Photoshop Precision Details 2 and Topaz's Gigapixel.  So far, I am liking ON1 Resize the best.

Anyway, he started with 8 x 10's and had the same image taken with an iPhone, A7iii, A7Riv and A7Riv in 240 Mpixel mode, and to then have his panel try to decided which ones look the best to worst.

The then simulated a 16 x 20 by cropping the originals and printing more 8 x 10's, and again had his panel judge them.

And he did the same with 32 x 40 and 64 by 60, always just printing 8 x 10's of smaller and smaller crops.

The results sorted themselves out as expected.

Now what would be interesting to add to this would be to resize images and put them in the mix for the panel.  For example, if the A7iii is resized 200% and the A7Riv is not resized, the 240 Mpixel version is not resized also, how would the panel sort the resultant 8 x 10's not knowing what produced the image?

I suspect that the resizing would bump up the standing of the A7iii as long as pixel peeping is not possible.  But the panel was only holding 8x10 prints, so they are limited in how close they could inspect the picture.
