Ah, this itouches on one of my ongoing issues, fitting a 3:2 ratio image into an industry standard 4:5 mat/frame world.
So, first of all, the survey is fine but A3 paper
isn't 12x16", it's 11.7x16.5" (see
Paper size - Wikipedia, the free encyclopedia ) so if you do borderless printing it will clip. If you leave a margin/border/self-mat around the image you'll have to print
smaller than the paper size.
A full 3:2 Pentax image from a 6mp sensor has to be scaled up to fit and the closest full 3:2 image size with the smallest margin on A3 paper will be 130% for a 10.x16.3"... for a 10mp or 14mp image it will have to be scaled down to fit.
But... since most frames/mats commonly available are in the 4:5 ratio, to fit "standard" frame/mat combinations you will need to either output the image on the paper for the best size possible as a bordered (self-matted image), or, crop to a standard frame/mat combination (an 11 x 14 mat = an 8 x10" image opening) and that means cropping out about 25% of the image .
Unless I''m doing something wrong,
