Attached below is a 24mp image, see the content? You're as inane and stupid
as your comment.

I presume that it's the same as said in other ways, a fool with a tool
is still a fool. Unnecessary, perhaps a little inane, but still worthy
of repeating.

I've got 6,6 vision without glasses, but at 52 I can't focus at 10
inches. At a quick measure, about 14 inches is my limit. If you peer
at prints at 10" (with reading glasses I assume) then that's overkill.
If you do that in a gallery around here, then you might very well be
asked to leave.

You mean a 6mp crop from a larger image - or one taken with an old 6mp
dslr? With the former, then if the image wasn't absolutely nailed
(focus etc) then I agree. From an old 300d, D70 or whatever, then I
don't agree - they can be stunningly detailed at 8x10. A4 borderless is
quite a bit larger, especially if you crop off the end to get a 3:2
format image to fit.
It just doesn't render detail and textures as well as I like.

The R1800 and 2400 are mechanically the same printer with different
exterior cases, I assume Epson did the same with R1900/2880.
"Print engine" wasn't the correct term. To be picky, the 1800 fires
smaller droplets (1.5 vs 3 picolitre), so might outresolve the 2400, but
either will easily resolve >300dpi.
The R800 is a slightly different beast - despite using the same inkset
as the R1800, gamut and tonality isn't the same.
With the new Epson A3+ range, they reduced cartridge size from about
13ml to about 10ml and increased the price a bit too. That was a very
nice thing for them to do - not.
Considering that the 800/1800/1400 are now 5 year old technology, it's
surprising how very marginal any improvements have been in newer models.

So you feel a 20MP APS sensor will be an improvement? How about a 40MP
full frame one? And you don't think they will continue this trend?

So you believe a 20MP camera with the same size sensor will be even
better? That is where this is headed.. And does a G2 and a G11 have the
same size sensor? Sorry I don't know the answer there.

Given good lens resolution, enlarging was the real kiss of death of
film images.
