From: HeroOfSpielburg on
Hello,

This is a subjective question, mostly. I have an art show next week
and wanted to blow up a negative to a pretty large size, long print
about 20x40, for the fascade of my booth. The staff at the print shop
said beyond 14x17, it doesn't look very nice.

I imagine that the grain gets really large, and the color dots start
separating? I dunno, maybe it looks kind of cool, and the fact that
it's over three feet long overpowers any negative reaction from
graininess?

I'd just try it for the hell of it but a print that large costs me
over 120 dollars, so I'd like some feedback first. :)

Any and all opinions, thanks!

Depends on how far away the viewer is:

Mark 40 inches on the wall, stand at the viewing distance, and hold a
print up so it just covers the 40" marks. If the print is far
enough away - say a 4x6" print at 12" - it may look ok. If a 4x6"
print is 3" from the tip of the nose then your 40 incher is going to look
pretty awful.

With Tech Pan and the old Ektar 25 it was possible to get 16x24's
that looked acceptable at a 2 foot viewing distance.

35mm enlarged to ~40" wide produces a ~40 x 24" print.

That's a sure sign it looks really crappy to anyone else.

It depends:
- on the viewing distance
- on the film used
- on the subject

I have a lot of prints at 16x24" and that works quite well. I have fewer
prints on 20x30" and those are no problem either (except that they are too
big to handle easily).

Of course, 40" is quite a bit bigger.

For me, a digital 20x30" print costs less than 10 euros, so it is easy to
experiment.

Note that at those sizes, sharpness is quite a bit different from what you
can get away with at smaller sizes.

There are big differences in grain. Some consumer color negative films have
ugly grain, whereas the now discontinued Kodak Supra 100 had really nice
grain.

Typically, grain will be visible in sky. But with films that have nice grain
that should not be a problem. Sometimes, dark areas (that cannot be rendered
as black) also create problems.

by. It was allowed to keep its horse, since horses were so cheap to make.

It depends on the shot. Exposure must be right on, focus must be right on,
and there can be no camera shake.
That said, I've got a shot of sunset on the Gulf of Mexico, taken on board a
ship, handheld, and about a stop underexposed. The 20"x30" print (printed
optically on standard RA-4 color paper) looks great. When you get close to
the print, you will see the grain.
I routinely print 16x20 prints from 35mm. If the neg is good, the print can
be good.

I'd be willing to bet that the local print shop can't make a print over
14x17.

1) Their equipment is only big enough for 14" paper

2) They can, they just think it looks bad to their eyes, and they
assume the customer has the same quality standards.
