DSLR picture resolution and wallpapers

-

hello everyone,

might have simple question you.

using d3200 raw+jpeg (i don't know if ever use raw, find image same jpeg, edit jpeg) anyway... wondering, take shot, modify , set wallpaper on imac 27in doesn't fill screen. picture resolution 6016 × 4000 (24,1 mp). suppose reason , not 16:9. there make fit on imac 27?

thank
 

as raw editing, when @ image in editor aperture or lightroom, see on screen jpeg preview looks same without regards whether have selected raw or jpeg image source. raw equivalent digital negative , can "developed" in software degree jpeg file can't. see on screen still jpeg, though.

image won't fit because of aspect ratio, not resolution. resolution number representing linear number of pixels per inch while aspect ratio length width measurement of image. fit screen image has have same relative length , width viewable area of screen. have crop or resize image match screen. have photoshop type of stuff aperture too. don't know lightroom or preview. in ps open image , select crop, enter dimensions of screen in length , width fields @ top , hit enter crop it. of image lost can move crop preview window around liking.

hope helps.

dale
