if you look at the offerings from Stouffer stouffer.com You may find what you're looking for but, if you want something hat high a resolution to photograph, just photograph something of lower resolution(such as the USAF1951 target) at from farther away!Thanks everyone! @Theo Sulphate
I second your questions Theo! Thats actually something im thinking about too in relation to my original question.
I was originally looking at lithophanes, is that in the same ballpark as your thinking?
Im curious to know if you can etch/emboss in a high dpi/lpmm.
Did you manage this with "compugraphic phototypesetting equipment"? Can you elaborate?
Generally speaking, lens resolving power is limited to the weakest link in the optical system. Putting a Leica lens in front of a simple phone optic, will render only as well as the iPhone lens. Some lenses are compound designs where elements are added - supplementary lenses on the Fuji X100 series for example - which are designed with the base formula in mind.Will a supplemental lens with a "higher resolving power" than my phones lens help to retrieve more data in theory? Or no?
Because you tend to sit at a distance that is better suited to the smaller screen than a larger one.So why do images displayed on a smaller TV look better, sharper and more contrasty than the same image on a larger TV screen or print?
I meant from the same distance. Smaller looks sharper, clearer, with more contrast.Because you tend to sit at a distance that is better suited to the smaller screen than a larger one.

A 4k TV is 8 megapixels (8 million pixels overall). Such TVs are often 55-65" in size. If you enlarged a 15 year digital camera image to make a 6ft print, you wouldn't be surprised if the quality was lacking. That's what your typical large screen television outputs - okay from the back of a bar, not good in a domestic setting..I meant from the same distance. Smaller looks sharper, clearer, with more contrast.
My curiosity about that leads to these questions:
1. Is it possible to etch on glass or imprint on paper 250 line pairs (or more) per millimeter? I think so, because I worked with Compugraphic phototypesetting equipment which claimed 5000 dpi (fonts and symbols were stored electronically on disk and film was scrolled past a light emitting surface).
2. If (1) is true, what optical limitations prevents those 250 line pairs from being faithfully projected from the source to the sensor? That is my real question.
I think it needs to be added to Adrians explanation of electronic sensor contrast, that the 100% contrast is purely hypothetical for straight horizontal or vertical lines of the perfect width, aligned perfectly with the sensor sites.
Which never happens.
