----- Original Message ----- From: "David Dyer-Bennet" : It has the benefit (?) that all the sheets are the same aspect ratio. : That's a benefit for making different size prints of the same image -- : no recropping, and it always fits perfectly. But perhaps a disadvantage : if you like some variety in aspect ratio. : : It has the disadvantage that *all* the sizes are completely weird : numbers (and they only approximate them to the nearest mm, I believe). : How many pairs of figures like "210mm x 297mm" can *you* remember? given photographers are all familiar with the square root of two and knowing we start with one paper size it's not hard to work out ;) k
