The excuse the paper industry is not geared to produce 8 x 12 Photo Paper
because it is too expensive to switch over to that size what excuse can

Almost none of the digital images I have printed have been uncropped,
which blows the argument straight out of the water. Here in the UK we
get metric paper - A4 & A3 - but it wouldn't matter what paper size I
printed on, I still both (usually) crop the digital original and trim
the print. I want the most pleasing end result, and am not going to
cry over unprinted pixels. Additionally, I personally regard the 3:2
proportion as usually not as pleasing as the metric paper ratio - it's
too long & narrow.

I agree with you wholeheartedly, but as a fully paid up pedant I must correct you on one point: there is nothing metric about A4. It is an ISO size, but does not divide neatly by 10. You can, if you wish measure it in metric units, but that is up to you.

I'll go away now. ;-)

Richard,
You're saying it's not metric?
Why then?

http://en.wikipedia.org/wiki/Paper_size Main article: ISO 216
The international paper size standard, ISO 216, is based on the German DIN 476 standard for paper sizes. Using the metric system, the base format is a *** of paper measuring 1 m² in area (A0 paper size). Successive paper sizes in the series A1, A2, A3, etc., are defined by halving the preceding paper size parallel to its shorter side. The most frequently used paper size is A4 (210 × 297 mm).

This standard has been adopted by all countries in the world except the United States and Canada. In Mexico, Colombia and the Philippines, despite the ISO standard having been officially adopted, the U.S. "letter" format is still in common use.

ISO paper sizes are all based on a single aspect ratio of the square root of two, or approximately 1:1.4142. The advantages of basing a paper size upon this ratio were already noted in 1768 by the German scientist Georg Lichtenberg (in a letter to Johann Beckmann). In the beginning of the twentieth century, Dr Walter Porstmann turned Lichtenberg's idea into a proper system of different paper sizes. Porstmann's system was introduced as a DIN standard (DIN 476) in Germany in 1922, replacing a vast variety of other paper formats. Even today the paper sizes are called "DIN A4" in everyday use in Germany.


Noted.

I retract my comment.

Let no man say I'm unreasonable. Accurately, at least.
