A proposal for a new digital camera format

2004 Ellis Vener.

Here is my optimistic take on the whole Nikon DX lens thing. Nikon
may be developing a two sensor size strategy. The DX lenses are for
the now rather extensive family of cameras that have the smaller
sensor: Nikon D1, D1H, D1x, D2H, D100, D70, Fuji S1,S2, S3, and Kodak
DCS 660 & 760 bodies all use roughly similar size sensors and while
most of those are not current product a lot of these bodies are still
in circulation and Nikon does have a history of looking backward and
forward at the same time. At the same time a new larger sensor camera
may be in development.

By larger sensor I earnestly hope that someone at Nikon is looking at
the way images are actually reproduced by professional and amateur
photographers alike and realize that very few images actually get
printed with the full 2:3 aspect ratio of a 35mm negative or slide.
Most in fact get printed on a piece of paper that is 8.5" x 11", which
is a 1:1.294 aspect ratio. So here is my modest proposal. Nikon should
pioneer a new digital sensor size: 1" x 1.3" in size with a resolution
of 3060 x 3960 pixels - which yields a 12.12Mp file. ( I have rounded
off the numbers slightly and since I am not an engineer, have not
taken into account actual pixel sizes. This would yield a non
interpolated and barely cropped full bleed image on 8.5" x 11" media.

Currently in the DSLR group the only camera that meets or exceeds this
is the Kodak 14n and it's newly (actually today) announced successor,
the KODAK PROFESSIONAL DCS Pro SLR/n Digital Camera (more details at
http://www.kodak.com/global/en/ professional/products/cameras/proSLR/
proSLRIndex.jhtml?id=0.1.18.18.5.14&lc;=en). My proposed new sensor size
format doesn't have to be 1" x 1.3", it could be as large as the image
circle of the lenses allow. However, for a camera manufacturer the
downside of using a sensor that is larger than 1" on the short side of
the format would be having to retool for new prisms, mirrors,
shutters, and chassis. On the other hand this obviously presents no
problem for a digital back for a medium format camera.

But what about the Canon EOS 1Ds? To start with it is an 11.2 Mp
camera in a 1;1.5 aspect ratio. Crop it down to the 1:1.3 aspect ratio
and you lose 1.5Mp of image. In other words, it effectively becomes a
9.7 Mp camera. So to fill an 8.5" x 11" piece of printed media --
whether a desktop ink jet printer or standard magazine page -- either
you or the printer is goingto be doing some interpolation for optimum
resolution.

I am picking 360dpi as an output resolution because that is a standard
resolution for desktop inkjet printers. while a lot people say pick
300ppi as a printing resolution feedthat to an Epson or canon or HP,
etc printer and the printer is either interpollting down to 180ppi or
interpolating up to 360 dpi depending on what it thinks is best. My
theory is that this interpolation is one of the causes of prints from a
digital file to look "digital."

It doesn't have to be Nikon that does this. Frankly I do not care if
Nikon, Canon, Imacon, Leica or Kodak, etc. does this. But it does not
make sense to abandon the sacred cow of the 1:1.5 aspect ratio format
size that digital SLR makers have inherited from film?
