Foto.com (based in Belgium) produce great looking poster prints for me occasionally, up to 70cmx100cm .... Colours that match my images on screen and very sharp looking at normal view distances. Very happy for the reasonable prices too, even with postage to the UK.
I know very little about image sizing, but I understand these sizes are bigger than the K7's full resolution at 14.4mp .... So I presume that to get these big prints looking good there must be some boosting taking place ... That's called interpolation isn't it? Anyway, it must be a good program they're using.
