Is there anyone who has not yet seen an Apple iPhone billboard?

It answers the question “How large can you blow up an iPhone image!
It all depends on viewing distance!

Google: “Apple iPhone billboards”

I’ve seen some of those. Pretty amazing. From a distance, though. There is also supposed to be some movie shot entirely with an iPhone. I can’t remember what it is, but there were some clips in an article I read, and it was pretty high quality video. The new iPhone 12 Pro Max is supposed to be a real game changer when it comes to video.

Yes in-deedy, WingPilot!
The point is that the concept of “Normal Viewing Distance - NVD - (one and 1/2 times the diagonal dimension of the image - regardless of the size of the image and what sort of camera it was made with) WORKS!

IT JUST WORKS!!

If a 6”x8” image looks excellent viewed at a distance of 15” (but if looked at really closely with an ocular loupe would be all pixelated), that same image file enlarged to 36” x 48” will look just as good viewed from a 7’ or 8’ distance (but if viewed from 15” would be all pixelated!)

Y’don’t believe it?
Next time you see a nice sharp image on a billboard along the Interstate, just pull over. Get out, climb the fence, trudge up to it and view that billboard from 10 feet away.
I can guaran-damn-tee three things:

1. The image will look terrible,

2. You will understand why the best photography judges view every image from NVD! and

3. You’ll get a ticket for illegal parking!
