the images i have at hand don't have resolutions set in the image explicitly (would they be evaluated at all?), but give these results: $ exiftool infile.jpg [...] X Resolution : 1 Y Resolution : 1 Resolution Unit : None Software : Hugin 2013.0.0.4692917e7a55 [...] Image Size : 12032x3013 $ convert infile.jpg outfile.pdf $ pdfinfo outfile.pdf [...] Producer: ImageMagick 6.7.7-10 2013-12-22 Q16 http://www.imagemagick.org [...] Page size: 866304 x 216936 pts i don't know if a jpg's resolution can be any more unspecified than by unsetting the unit. ([1] suggests there isn't; if there is, let me know and i'll try to get hugin to export a properly undefined resolution). the math of this implies 72pts per pixel (1 pixel per inch if i'm not mistaken), which makes the critical size achievable with common cameras and 360° panoramas.
