Maybe if you are printing roadside billboards.

Ever watch people in gallery? They walk right up to prints. And if your print looks fuzzy
or pixellated at a viewing distance of 2 feet, it won't sell.

Reality check: the competition for fine art photography is reproductions (made by
photo-lithography). An original print must look better than a litho.

And unlike photographers, most lithographers are trained and understand the theory.
They use step wedges and resolution targets and calibrate their equipment.

All true .... but 12MP is more than enuf to deal with those facts.

AGREE ........one of your better comments

Thanks, I appreciate it.

Most large prints used to look much better than a high quality litho.
Now most look the same or worse. Lithos haven't improved.

Compare the level of technical knowledge in this article published
in The Lithography Expert with that on UHH:

The Lithography Expert: The Rayleigh Depth-of-Focus

Consumerism has inflected a massive "dumbing down" on photography.
But lithographers are as knowledgeable as they ever were.

The D700 is an exceptional camera even at 12 mp. It is almost legendary in terms of the superb image quality it produces. I once read a 'scientific' explanation about why this so. Keeping it simple, the surface area of each pixel on its sensor comes it at over 80 square microns, one of the highest individual pixel areas of all 'commonly' used high-end sensors. I think even the D710 dropped to less than half that area per pixel on its newer, higher megapixel sensor. That was the explanation given as to why the images produced by the D700 are considered so stunning, even today.

If it were mine, I would keep it forever.

If I've learned one thing it's this: never part with a camera you like, assuming you'll be able
to buy another one like it or that the new ones will be better.

Come to think of it, that also applies to musical instruments and especially guitar amplifiers.
If anyone knows of a '57 Fender Tweed Deluxe amp that sounds like Neil Young's, please tell Neil.
He's bought dozens of them over the last 40 years trying to get a backup amp, but they don't
sound the same.

The same goes for analog effects pedals, e.g., distortion. Silicon transistors don't sound like
germanium, and germanium have to be hand sorted for gain. It's very difficult to find the
combinations of gains that sounds the best, or to build two pedals that sound exactly the same
(speaking from personal experience building pedals).

Digital pedals are much more manufacturable, but if you use more than one, you get re-sampling.
Two digital pedals: A to D to A to D to A. Three: A to D to A to D to A to D to A.
The sampling rate used in most pedals was designed for CDs: one sampling, not two or more
in succession.

Every technology has its good and bad points. The trick is to use the best one, not necessarily
the latest one.

Is that the same gemanium that I have in my flower bed? 🌺
