I have a feeling that digital projection using consumer projectors will be
replacing 16mm projection more quickly than most of us would like -- there
is very little 16mm release printing going on these days. With the death of
reversal stocks, 16mm release prints are either made off of the original
negative (which is dangerous and more expensive) or off of dupe negs --
which add two generations to the process (IP and dupe neg) and greatly
reduce quality.

DVD and BluRay are not the solution, at least not at the moment, I don't

There are some very good codecs that do not need fast computers or hard
drives to play back high resolution files at 24 fps. I like the Cineform
codecs a lot -- and we use them with the Kinetta Archival scanners. You can
capture at greater-than-HD resolutions (we use 2.4K x 2K for our smaller
scanner, 4K x 3K for the big one) and set playback at whatever speed you'd
like -- so those working at 12-16-18 fps can get real 12-16-18 fps
projection, not always simple with film projectors. You also get the
advantages of 10 bit log rather than 8 bit images.

We use to travel with projectors and speakers and amps and an EQ with room
analyzer -- a pain. I could see easily travelling with a bright digital
projector and a small computer to feed it -- or a dedicated box like WDTV or
similar, even Apple TV is ok but limited right now to 720P.

For those of us wanting to use every pixel for 4:3 film projection, an
expensive option would be to use a 1.33x anamorphic projection lens rotated
90 degrees, and stretch the image electronically so that 1920 x 1080 with
squeeze projects as the equivalent of 1920 x 1440 through the lens. (These
lenses are not yet affordable.)

There will be 4K projectors from EPSON in the next year or so that should be
in the high-end consumer price range -- these might be amazing.

I love film projection. I wish I could foresee a long life for it,
especially in 16mm. But Kodak seems to care only about cheap ink-jet
printer ink these days -- IDIOTS! -- so we will have to improvise and find a
replacement that doesn't lose the qualities that are important to us all.
