I hope this question makes some sense. My camera takes pictures at a 1.5
ration ( 3504 X 2336 ). However, when printing to a 13 X 19, the software
allows me to go bordered or borderless (full). Doesn't that cause a skew?
I
also see places that will print 36" X 48" for you. Again, a different
aspect
ration. The 4X6 seems to be a true ratio, but I am stumped on the more
popular sizes.

3504/2336 = 1.5
but
19/13 = 1.46

so the results will depend what the software does. Assuming you want the
biggest print possible it can either..

a) stretch the image vertically slightly to make the aspect ratio 1.46
b) maintain the aspect ratio and scale it to the height (you loose a bit off
the sides).
c) maintain the aspect ratio and scale it to the width (you get white
borders top and bottom).

Draw rectangles on paper with the right aspect ratio and you will get the
idea.

Other paper sizes...

6/4 = 1.5 so its a perfect fit. No need for cropping or stretching in one
direction.

48/36 = 1.333 so stretching or cropping is required. Best to crop the image
to a 1.333 aspect ratio before you send it to them.

10/8 = 1.25 so stretching or cropping is required.

By the way ...When you select borderless printing is normal to loose a
little bit of the image around ALL edges. This is to ensure the image goes
right over the edge if the paper isn't exactly aligned or straight in the
printer. This is in addition to any corrections for the aspect ratio,
