兩部相機都係2576 x 1972

但係如果一機既dpi係72 dpi ,
另一部係 230 dpi

實際上有咩分別?

[man1492]

Resolution has no physical size information, depends on how you present the "dot"; dpi is "Dot per Inch", a 2576 x 1972 photos on 72 dpi gives 36"x27" print; a 2576 x 1972 photos on 230 dpi gives 11" x 9" print

咁我有兩張相

一張係v570影既，睇EXIF話dpi係230dpi
而另一部pentax既相EXIF就72dpi

咁佢呢個EXIF話既dpi意思係指乜野呢?
